Question 1

Role of the NUCLEUS?

Answer 1

Contains DNA in animal, plant and fungal cells to control cell activities

Question 2

Role of the PLASMID?

Answer 2

Small ring of genetic material found in bacterial cells.

Question 3

Role of the CELL MEMBRANE?

Answer 3

Selectively permeable membrane that controls the entry and exit of substances such as oxygen, carbon dioxide, glucose and waste to and from cells.

Question 4

Role of the CYTOPLASM?

Answer 4

Stores the cell organelles and it is the site of chemical reactions.

Question 5

Role of the CELL WALL?

Answer 5

Outer layer of plant, fungal and bacterial cells and it provides support and protection to cells by giving them a rigid structure that prevents them from bursting.
