two types of cells
plant and animal
1 of 71
similarities of plant & animal cells
they both have a nucleus, they both have a cytoplasm, both have a cell membrane, both have a mitochondria and they both have ribosome's.
2 of 71
nucleus
contains DNA
3 of 71
cytoplasm
a gel-like substance where proteins such as enzymes are made
4 of 71
cell membrane
it holds the cell together and controls what come in and what goes out.
5 of 71
ribosomes
this is where proteins are made in the cell
6 of 71
plant cells have but animal cells don't
rigid cell wall, vacuole, chloroplasts
7 of 71
rigid cell wall
it supports the cell and strengthens it
8 of 71
vacuole
it contains cells sap which is a weak solution of sugar and salts
