INSIDE A CELL!!! by caroline schlobohm

today were watching a video so here are a few notes

Kind of animals/plants that each kind of cells are in

Eukaryotic- plants, animals, fungi, protoctista.

Prokaryotic- monera

cheek cells have only a membrane, obviously not a plant cell.

-membrane is the boundry of the cell, it protects the cell, doesnt let alot of thing into the cell.

often more than 1 membrane

Nucleas

2 membranes, membrane envolope. (inner membrane, outer membrane)

Nucleas creates RNA that ribisomes turn into proteins

cytolsol takes up mmore than half of the cell

-mitochondria the respotory system-

chloroplasts absorbes light energy

cells requiring alot of energy have alot of mitochondria

mitochondria- cellular resperation occures here

Rough Endoplasmic riticulum isolates and transports proteins

smooth endoplasimic riticulum protects cell from harmful compounds

mitochondria has 2 membranes

golgi apparatus consits of flatened vesicles, like a proccesing station in the cell.

in most plant cells, a single large vacuole is present

Garrett Pope December 17,2010

Today we are going over the parts of a cell... here they are!!

Cell Wall- Keeps the cells shape and acts as protective barrier.

Cell Membrane- Lets certain things in and certain things out. It is like a filter. Every cell has a cell membrane.

Mitochondria- provides the energy that the cell needs to move, divide, and contract. Power center of the cell. Dividing means reproducing. Bacteria cells don't have mitochondria.

Ribosomes- Creates proteins for the cell. Does protein synthesis. Has RNA.

Chloroplasts- Are in plant cells and makes it green and has color. Uses energy from the sun to make food for the cell. Converts Carbon Dioxide in water to sugar. This could also be called hydrosynthesis.

The rough endoplasmic reticulum- transports proteins from the cell.

Vacuole- stores nutrients, waste products, and adds water. Also releases all of these things.

Smooth endoplasmic reticulum- breaks down of toxins.

Golgi apparatus- packets macromolecules and transports them into the cell. Tags the macromolecules. (Tells it were to go).

Nucleus- It is the most obvious organelle. Is were the DNA is stored. Supplies the cell with unique charecteristics.

Cytoplasm- Makes up the cell. It keeps the organelles in the same place.

Lysosomes- Contains enzymes for digesttion and kills viruses, bacteria, and breaks stuff down.

Synthesis- Synthesis means to create.

Dehydration Synthesis- to create something by loosing water.

Mr. Finley put blue dye into a cup of water. It is turning the water blue. Going slowly. Spreading. Going were there is less dye. Doesnt want to be so packed together.
This is what happens in a cell membrane.

Paramecium


Today in class, we watched a video on the smartboard. We saw a paramecium cell moving around and spinning. We knew that i he paramecium cell was a bacteria cell because we believe that we saw capsules and cillia( cillia are tiny hair-like structure on the outside of the cell to help it with motion), which are characteristics of bacteria cells. We also knew that it could not be a plant cell because a plant cells don't move. We also thought that it was a prokaryotic cell (unicellular and doesn't have membrane bound organelles). The paramecium in the video was eating a red substance, which enabled us to see it because they are clear (like our cheek cells that we tested in November). The red stuff that it was eating was similar to the methyene blue that we used on our cheek cells because they both helped us to see the cells.

***Also, remember tto print out the study guide for Tuesday's test!!***

From the Structures To the Functions

Today in class we first discussed what we should do if we needed help in science, brought up by one of the students. Some ways to get help would be to

1. Ask Mr. Finley
2. Post questions on discussion board
3. Post a question on the blog
4. Text or email Mr. Finley
5. Text or call your friends with the question
6. LAST OPTION: Ask Mr. Finley for a tutor that could tutor you

Once we discussed the ways to possibly get help, we started to move on. We're moving on to functions of the cell parts. We used the 2 original simulations to get our answers

• www.cellsalive.com/cells/3dcell.htm
  
• www.learn.genetics.utah.edu/content/cells/insideacell/

We were trying to find the functions of the:

• Cell Wall
• Cell Membrane
• Ribosomes
• Rough Endoplasmic Reticulum
• Smooth Endoplasmic Reticulum
• Mitochondria
• Nucleus
• Vacuole
• Cytoplasm
• Chloroplasts
• Lysosomes
• Golgi Apparatus

Mr. Finley made it very clear to PUT THE DEFINITIONS IN OUR OWN WORDS. Soon after we found all the definitions and put them in our own words we had to go. If we didn't find all the definitions we had to do them for homework.

We are also having a test on Tuesday on the cells. The study guide for the test is posted on the Cell Reproduction page. (Link: http://http//www.npsd.k12.nj.us/20222069133223760/blank/browse.asp?A=383&BMDRN=2000&BCOB=0&C=59029) It would be awesome if someone did an eather pad for the test like the one Claudia made last time. Here's a link to the site to make an eather pad: http://www.eatherpad.com/

We also discussed Mr.Finley's birthday, he said it was horrible. His printer wouldn't work. Hopefully it works today. But anyway, HAPPY BELATED BIRTHDAY MR. FINLEY!!! :)

Eukaryotic and Prokaryotic Differences

We started class by finishing the Mythbusters video from yesterday. Then we labeled the parts of a plant, animal( both are eukaryotic cells), and bacterial cells (a prokaryotic cell). We discussed the parts of a bacterial cell. The parts are: cell wall, cell membrane, flagella, DNA, and pili.
Mr. Finley showed us a euglena and asked us if it was a prokaryotic or eukaryotic cell. He also asked us, "what makes a cell prokaryotic? Shape vs. structure." The answer was a lot different from what I expected it to be . You might think it's a prokaryotic cell because it looks like a bacterial cell. Or you might think it's a eukaryotic cell because it has some of the same cell parts as an animal or plant cell. It's an animal cell (eukaryotic cell) because it has a cell membrane, but it also has chloroplasts like a plant cell. Since it has animal and plant cell parts, a euglena is a one-of-a kind organism. It can eat (animal characteristic), but it can also make its own food (plant characteristic). A eukarotic cell can be single celled or multicellular. A euglena is a single celled organism with both plant and animal characteristics, which makes it one-of -a kind. It was interesting because I thought it would be a prokaryotic cell.
By the way.....today is Mr. Finley's birthday!!!

Samantha Caggiano's Blog

Today in class we had a sub. He left use a packet to read and answer questions on the back. So we had to read the article and take notes about it.
Notes-

• Cells are amazing, variable, beauitiful, functionally superd, a consept of genious; they work alone or in groups with equal ease.
• Cells are the basic unit of life, all living things, -------- are made up of one or more cells.
• Organisms that exists as single cells are called multi-cellular.
• All living things are divided into two major groups depending on how their cells are set up, these two groups are Prokaryotes, and the Eukaryotes.
• Eukaryotes have areas inside the cell separated off from the rest of the cell by membranes, like the cell membrane.
• Prokaryotes do not have a nucleus, mitocondria or any other membrane bound organalles.
• All the Prokaryotes (bacteria and Archaea) are unicellular, only Eukaryotes: - the protista, some Fungi and some Plants are multi- cellular.

Small Cells------- Big Organisms

• Most cells are tiny, too small to be seen with the naked eye, yet we can easily see the trees and elephants ect.

What is a cell-

• The simplest answer is that a cell is a container, like a box or a bottle or a jar.
• It has an inside and outside, and something like a wall in between to let us know where the outside begins and the inside ends.

Not finished do not grade still more to write

Comparing Cells

Today in class we went over homework. Our assignment was to compare three cells (bacteria,animal,and plant) and say the differences and similarities.

Observations:

-That the bacteria cell was magnified because it was smaller
-Bacteria cell was thinner
-Bacateria and plant cell have cell walls (animal doesn't)
-The bacteria cell had strings on it which are callled Pili
-The bacteria was the only one without a nuecleus
-The dark area in the bacteria cell is the DNA it is dark because there is more DNA in that area
-Each cell has a cytoplasm or a sytoskelton
-Each cell has a cell membrane
-Each cell also has ribosomes

The prokaryotic cell is the bacteria cell and the plant cell has the eukaryotic cell

Prokaryotic

-Single cellular
-Smaller than eukaryotic cell
-Bacteria
-More organized than the eukaryotic cells

We agreed that the eukaryotic cells are more complex and organized because all the organels are organized and the prokaryotic cells are all messy and not grouped.

Mr.Finley asked us which cell cames first eukaryotic cells or prokaryotic cells. In our groups.
Some groups said that the eukaryotic cells came first because it was more organized and other groups said the prokaryotic cells came first because they weren't as complex. My group said that the eukaryotic cells came first.

Is it Alive

First we talked about the homework and what was living or not. With most of the plants, it depends. If the plant is picked or chopped down then it is slowly dying, but if the plant is not alive, then it is living.
Things that are living:
-Tree
-boy
-rabbit
-grass
-egg
-bacteria
-cell
-mushroom
-potato
-leaf
-butterfly
-pupae
Things that are non-living:
-rock
-wind
-cloud
-feather
-sun
-river

-fossil

Things that are dormant:
-seed
-hibernating bear
Things that are dead:


most will thik that a river was living, but it is not. The things that are inside of the river are living, but the river itself is notliving.

things that are inside a cell going smaller and smaller
Cell -> comes from other cells

Organells

molecules -> h20 (water)

types of elements -> categories
(atoms) +Hydrogen
+Oxegen
structures
tiny spheres or particles

-Living things are made up of things that are not living

Q: are other things made up of molocules?
A: yes everthing has molecules even if it is living or non-living

A.M.

from the homework we thought that the cells are alive when you die until there are no more neutrons. then form that we said that if you want to salad for lunch is it alive. we said that it is a live but it is slowly. when you eat it you get the neutrons. some parts are alive but some are not. but some said that if it is die how dose it give you neutrons. that it is not alive when you are eating it because it had died but at one point. some said that it still has neutrons but it stops growing. it will die and it will have neutrons but it can not have more neutrons so it is dormant. the cells are dieing but the are not died. they start to changing color and dieing. when you pick a flower they are not died but they are dieing. they will die some day but not right away. as the plant start dieing the cell wall starts dieing too. then it gets ruder like. the refrigerate slows down the dieing broses. out of all of this i think cells are alive but they are dieing.

Dec. 3rd 2010

• Today in class, what we did is we took out our homework. then, mr finley handed out our quizes from moday. he told us that alot did mad and a few did ok. he said we can correct them but you wont get extra point. this weekend, if you did bad, you have to study them! so in the future, you know what the cells part are. to the right, you see a picture of a picture of an image that was on the test. afterwards, a student in a different class, made a problem about the characterist of live. it was living, nonliving, and brother's dog. the students brother dogs died so he doesnt know what catorgy to put it in. so people were making ideas about where should it go. instead of brother's dog, we put dead. then, we talked about limabeans were would it go. we said the limabean would go into dormont catogory which has an arrow od potential to corve alive/living. an arrow to dead is was once living. so brothers dog goes to the dead catorgy and the limabean goes to the dormint catorgy. then we talk about a substance catorgy. we said dog. then under that we said puggle and beagle. after that we talk about the two terms, biotic and abiotic. biotic goes with the living catorgey and the abiotic goes with the nonliving catorgy. abiotic kills certain things alife. then, we talked about how cant an abiotic cant kill a virus? well a virus is alive and an a abitic is alive. after that little group talk, we talked about the homework. i think that the 1st student was right because an organisms are made up of cekks and so can cells. an other student said the 1st student wasnt wrong but wasnt right because depending on the cell area, it cant be made up of an organism. another student said said they do agree with each other. for example, if you take down a tree branch, you dont know if the cells in the tree are alive. a student said that when mr finley said when you scartch yourself, dead cells are coming off. which was right. then we talked about student two on the homework, we said they were on the right track. after we finish talking about the homework, we talked about a sing-cell. we studied a single-cell before which was bacteria and a parasite. are all cells organims. no there not because the red blood cells are not an organims. can a redblood cell survive by itself? yes it can and so can bacteria. thats what we talked/ did in class today! :)

Thursday December 2nd

Today in class we got right to work with finishing our characteristics of life slide show. My group put in our quiz on our smart notebook presentation, which Mr. Finley kindly gave us a mini lesson on. It was really helpful and adds to the presentation. When all of the groups were finished, we saved our presentations on Mr. Finley's flash drive, so that they can be graded and sent to the third grade class.

Next, We started an activity at the bottom of the cells and structures page of Mr. Finley's web page. Some groups started, but if your group didn't, or did not finish it, it will become homework due on Friday. The assignment was this: Organism versus a Cell - Discuss with a partner your thought on the following argument and pick a side. If you and your partner don't agree, you should both write down your answers.The argument is linked on the assignment page. ( I tried linking it here but i am not sure if it works)
