Answer 12

• Store and transport proteins & lipids.

- Can transport proteins and lipids out of the cell.

Question 13

What are lysosomes?

Answer 13

A special type of Golgi vesicles that contain digestive enzymes called lysosomal enzymes/lysozymes.

Question 14

What is the function of lysozymes?

Answer 14

Used to hydrolyse pathogens and old cell organelles.

Question 15

What structures do mitochondria contain?

Answer 15

• Matrix.

Question 17

What is the function of a cell wall?

Answer 17

Strong, structural wall that protect the cell from changing shape.

Question 18

What is the cell wall made of in plants/Algae?

Answer 18

Cellulose.

Question 19

What do vacuole contain?

Answer 19

Sugars and salts (cell sap).

Question 20

Site of photosynthesis (contain chlorophyll to absorb light energy).

Question 23

What are ribosomes?

Answer 23

Very small organelles that are made of proteins and RNA.

Question 24

What is the function of ribosomes?

Answer 24

To make proteins.

Question 25

What are specialised cells?

Answer 25

Cells that have evolved to carry out specific functions.

Question 26

What is an example of a specialised cell?

Answer 26

Epithelial cell (ileum).

Question 27

What is a tissue?

Answer 27

A group of cells working together to perform a specific function.

Answer 30

Small intestine.

Question 31

What is an organ system?

Answer 31

A group of organs working together to perform a specific function.

Question 32

How are epithelial cells adapted for their function?

Answer 32

• Microvilli - Increase surface area for more absorption.

- Lots of mitochondria - produce lots of ATP for active transport.
