Question 7

What controls what enters the cells and leaves it?

Answer 7

Cell surface membrane or cell membrane.

Question 8

What is the vacuole and what does it do?

Answer 8

It is found in the cytoplasm. It is filled with sap which important for keeping the cell/s rigid to support the plant. It contains a weak solution of sugars and salts.
