Question 10

What is the function of the nucleus?

Answer 10

It contains genetic material which controls what the cell does.

Question 11

What is the function of cytoplasm?

Answer 11

It’s a gel like substance in a cell where most of the chemical reactions take place.

Question 12

What is the function of the cell membrane?

Answer 12

It controls what goes in and out of the cell.

Question 13

What’s the function of the mitochondria?

Answer 13

It’s where most aerobic respiration happens which transfers energy that the cell needs to work.

It supports and strengthens the cell. It’s made of cellulose.

Question 16

What is the function of a vacuole?

Answer 16

It contains cell sap.

Question 17

What’s the function of chloroplasts?

Answer 17

It’s where photosynthesis happens which makes food for the plant.

Question 18

What’s the function of DNA?

Answer 18

It stores the genetic information.

Question 19

What’s the function of plasmids?

Answer 19

They are small rings of extra DNA.
