Explain the difference between unicellular and multicellular organisms
unicellular are made of one cell
multicellular are made of 2 or more cells
Explain the similarities and differences between a cell wall and a cell membrane
cell walls are in plant cells and prokaryotes and provide structure to the cell
cell membranes are found in all cells and allow specific things to pass in and out of the cell
