november 18th 2010


today in class we started off with reviewing our homework with our tables and adding any new info to our lists. both animal and plant cells have a cell membrane, a nucleus, a ribosome, cytoskeleton, endoplasmic reticulum, mitochodria, golgi aparatus, lysosomes, and some animal cells along with plant cells have vacuoles. plant cells only have a cell wall and chloroplasts.

then, we labeled the parts of the grass specimen and the cheek cell specimen. for the animal cells, we saw the nucleus, cell membrane (both animal and plant cells). on both cells, the clear inside is a jelly-like part called the cytoplasm (cytoskeleton).
afterwards, we worked on our onion specimens. we cut off a tiny, tiny, thin piece of onion with a razor blade, cutting off one layer of onion about the size of a crumb. we put it on a slide, and put it under the microscope. it looked like a bunch of overlapped ovals or bricks that were different shades of green and brown. then, we ran out of time, so go to mr. finley for extra help on this lab.

  1. Cytoplasm and the cytoskeleton are two different parts.Cytoplasm is the gell stuff in a cell. The cytoskeleton is near the cell membrane and it is a travel way for things to travel in a cell.
