Question 13

Nucleus:

Answer 13

Is normally round. It’s acts as the control centre of the cell. It has the DNA

Question 14

Cytoplasm:

Answer 14

The watery liquid found between the nucleus and the cell membrane.

Question 15

Mitochondria:

Answer 15

Supply energy to the cell.

Question 16

Cell wall:

Answer 16

Found outside the cell membrane of a plant cell. Gives strength to the cell.

Question 17

Vacuole:

Answer 17

Space containing water, sugar and wastes - gives strength to the cell.

Question 18

Chloroplasts:

Answer 18
