Look at the following descriptions. Which cell best describes the type of cell that makes up a bacteria?
Cell A - I am smaller than other types of cells and have no nucleus or organelles. I am also called a prokaryote.
Cell B - I am a eukaryotic cell with a large vacuole, a cell wall made of cellulose and have many chloroplasts.
Cell C - I am a eukaryotic cell with no cell wall. I cannot assemble my own nutrients so I require transport of nutrients and wastes into and out of my cell.
cell A
cell B
cell C
How is cell division different between plant and animal cells?
Plant cells form a cleavage furrow while animal cells form a cell plate.
