7A Specialised rugby players Rugby players are different shapes and sizes because they do different jobs for the team. Like rugby players, cells are different shapes and sizes because they perform different jobs. Why are the players in a rugby union team different shapes and sizes?

Whose cell is it anyway?

Specialised cells Consider the root hair cell: It is “suited” to its job of taking in water and nutrients in 2 ways: It has a large surface area It has a thin cell membrane The sperm cell is another example of a specialised cell: Strong tail for swimming Vacuole containing enzymes

It is “suited” to its job of taking in water and nutrients in 2 ways:

It has a large surface area

It has a thin cell membrane

More specialised animal cells Red Blood Cell Carries oxygen around the body No nucleus and large surface area I.D: Function: Features: White blood cell Egg cell (ovum) Ciliated epithelial cell Nerve cell (neurone)
