Hola everyone. Today, Mr. Finley, was out but thats ok because we still were able to get a lot done. We got a heads start on out next unit cellular reproduction. Mr. Finley provided us with an online lab and our instructions were to take notes on it. It talked about the fact that growth in an organism is carefully controlled by regulating the cell cycle. Also it said that in plants the roots continue to grow as they search for water and nutrients.

Cellular reproduction has 5 phases.

Interphase is when the cell is engaged in metabolic activity and performing its duty as part of a tissue.

Prophase is when chromatin in the nucleus begins to condense and become visible in the light microscope as chromosomes.

Metaphase is when spindle fibers align to chromosomes along the middle of the cell nucleus.

Anaphase is when the paired chromosomes separate at the connectors and move to the opposite side of the cell.

Telophase is when the new membranes form around the daughter nuclei while the chromosomes disperse and are no longer visible under the light microscope.

So, After that we copied a table that I unfortunately cant place on this blog. :( But still, we got a good understanding of what is ahead in class.

  1. Hello Everyone!
    I read your blog and i thought it was very good!! I just have a couple questions-
    1.What is that a picture of above?
    2.Im so confused on interphase?!?!?! You said Interphase was when the cell in engaged in metabolic activity and performs its duty as a tissue. What does that mean? Does it replace old tissue? Does it make new tissue during interpahse!! And metabolic acticity?! Whattt?!?! It all seems like a foriegn language!!
    HELP!

  2. I'm not completely sure, but I think that it is a picture of a cell dividing.

  3. the picture is a cell that is in telophase. it is almost at cytokinesis and is getting close to splitting and becoming two completly seperate cells.
    Interphase is the beginning of mitosis. Not much has begun to happen yet, the next step, Prophase is when the chromosomes begin to become visible. THats a good question but a little confusing. What does happen during telophase.
