Question 1

Function of the nucleus

Answer 1

Controls the activity of the cell (by making proteins).
Contains the chromosomes - strands of DNA which carries the genes (each gene codes for a protein).

Question 2

Function of the cell membrane

Answer 2

Boundary between the cytoplasm and the cell’s surroundings. Controls what substances enter and leave the cell (selectively permeable).

Question 3

Answer 3

Jelly-like substance where chemical reactions occur

Question 4

Function of mitochondria

Answer 4

Carries out some reactions of aerobic respiration, producing ATP

Question 5

Function of ribosomes

Answer 5

Synthesises proteins from amino acids

Question 6

Function of chloroplasts

Answer 6

Absorbs light energy and uses it to carry out the chemical reactions of photosynthesis, making biological molecules for plant cells.

Question 7

Function of the cell wall

Answer 7

made of cellulose in plants. Helps to keep plant cells in a fixed shape.

Question 8

Function of the vacuole

Answer 8

Filled with a watery liquid called cell sap; stores dissolved sugars, mineral ions and other substances

Answer 9

Nucleus, cell membrane, cytoplasm, mitochondria, ribosomes, chloroplasts, cell wall, vacuole.

Question 10

Structures in an animal cell

Answer 10
