List the three statements that make up the cell
theory.
22
1. All living things are made of cells.2.
Cells are the basic units of structure and
function of all living things.3. All cells are
produced from other cells.

material?
26
vacuole

the endoplasmic reticulum then packages and
redistributes them to other parts of the cell?
30

35
How does the shape of a plant cell differ from
the shape of an animal cell?
36
Plant cells are typically rectangular in shape,
while animal cells are typically rounder in shape.
