How is a sperm cell specialised to fertilise an egg?
The head contains genetic information and an enzyme to help penetrate the egg cell membrane. The middle section is packed with mitochondria for energy. The tail moves the sperm to the egg.

What is a specialised cell?
A cell that is specialised for a particular function. Their structure is specialised to allow them to carry their particular function out.

How is a root hair cell specialised to absorb water and mineral ions from soil?
It is long and has a very thin wall, which gives a large surface area.
3 of 5
How is a leaf / palisade cell specialised to absorb sunlight and energy for photosynthesis?
It is packed with chloroplasts. Regular shaped, closely packed cells form a continuous layer for efficient absorption of sunlight.

How is a red blood cell specialised to carry oxygen to the cells?
It has a thin outer membrane to let oxygen diffuse through easily. Shape increases the surface area to allow more oxygen to be absorbed efficiently. No nucleus, so the whole cell is full of haemoglobin.
