Answer 2

A sperm cell- has a tail

Question 3

What do the special structure of Receptor Cells enable them to do?

Answer 3

Detect stimuli

e.g. the cone cells in the eye are light sensitive

Question 4

e.g. mesophyll cells of a leaf

Question 6

What do root hair cells do?

Answer 6

Increase the surface area of the root so that it can absorb water and minerals ions efficiently
