2.4 compare the structures of plant and animal cells.

Differences:

-        Plant cells have a vacuole

-        Plant cells have chloroplasts

-        Plant cells have a cell wall

Similarities:

-        They both have a nucleus

-        They both have cytoplasm

-        They both have a cell membrane

In a cell, cytoplasm is surrounded by a cell surface membrane. This is the boundary between the cell contents and its surroundings – it has very little strength but it is important for regulating the materials that pass in and out of the cells
