Epidermal cell

Question 1

Name 3 specialised animal cells.

Answer 1

Sperm cell
Red blood cell
Nerve cell

Question 2

How does the structure of the sperm cell help with it’s job?

Answer 2

Lots of mitochondria for travelling, streamline for speed, pointed head for getting into the egg, long tail for travelling the distance.

Question 3

How does the structure of the red blood cell help with it’s job?

Answer 3

biconcave disc shape for more surface area, no nucleus for more surface area, lots of haemoglobin to carry oxygen.

Question 4

How does the structure of the nerve cell help with it’s job?

Answer 4

large surface area at cell body for more connections, long axon to connect, myelin sheathe to increase the speed of impulses passing down the cell.

Question 5

How does the structure of the root hair cell help with it’s job?

Answer 5

long extensions to increase surface area, thin cell wall to increase osmosis.

Question 6

How does the structure of the palisade cell help with it’s job?

Answer 6

lots of chloroplasts to increase light absorption, upright cylindrical shape to absorb more light.

Question 7

How does the structure of the epidermal cell help with it’s job?

Answer 7

guard cells (stomata) to increase or decrease water & gas loss, waxy cuticle to decrease water loss, tightly packed together to protect the plant.
