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.

  2. Eukaryotic cells are more organized than prokaryotic cells and prokaryotic cells came first, you mixed them up.
