Question 3

What is the function of a Cell membrane

Answer 3

Is selectively permeable and controls the entry and exit of materials into and out of the cell.

Question 4

Function of a nucleus

Answer 4

Contains the hereditary genetic information (DNA) and controls some cell functions.

Question 5

Function of the cell wall

Answer 5

Provides structure and support to the cell. Made of cellulose in plants but other substances in fungal and

Question 6

Function of the cytoplasm

Answer 6

Site of chemical reactions.

Question 7

Function of the vacoule

Answer 7

Contains cell sap, stores water, sugars and salts

Question 8

The function of the ribosome

Answer 8

Site of protein synthesis.

Question 9

Function of the mitochondria

Answer 9

Site of aerobic respiration to provide energy to the cell.

Question 10

Function of the chloroplast

Answer 10

Contains chlorophyll and is the site of Photosynthesis.

Question 11

Function of the plasmid

Answer 11

Small circular ring of DNA.

Question 12

Describe how bacterial cells are different from animal, plant and fungal cells

Answer 12

Bacterial cells lack membrane bound organelles such as a nucleus and mitochondria. Bacterial cells have a very different cell wall structure from plant and fungal cells.

Question 13

Describe how cell walls of common plant cells are different from fungal and bacterial cells

Answer 13

Plant cells, fungal cells and bacterial cells all have cell walls; however, these cell walls are very different from one another.

Plant cell walls are made from CELLULOSE.
