Term
Name 4 properties of prokaryotes.
Definition
small, unicellular, are almost everywhere, divide by binary fission

cellulose wall
Term
what is the function of a cell wall in animal and plant cells?

plants = supports the cell and prevents excess water entering by osmosis, animals = Solids can only be taken in by vesicle formation, but excess water may enter by osmosis
Term
what is the differences in vacuoles in plant and animal cells.
