: Function: To move dust and microorganisms away from the lungs., Adaptation: Tiny hairs called cilia to help to waft the mucus along the airways., Adaptation: Lots of mitochondria to release energy for cilia to move., Ciliated Epithelial Cell, : Function: To help the body to move., Adaptation: Lots of mitochondria to release energy for muscle contraction., Muscle Cell, : Function: To carry nerve impulses around the body., Adaptation: Branching dendrites at each end to connect to other nerves or muscles., Nerve Cell / Neurone, : Function: To carry out photosynthesis to make glucose for the plant., Adaptation: Lots of chloroplasts to absorb light energy for photosynthesis., Adaptation: Tall, thin shape to give it a large surface area to maximise the absorption of light., Palisade Mesophyll Cell, : Function: To transport oxygen around the body., Adaptation: No nucleus so there is more room for haemoglobin, which binds to oxygen molecules., Adaptation: Biconcave shape to give a large surface area for diffusion of oxygen., Red Blood Cell, : Function: To absorb water and minerals from the soil., Adaptation: Long root hair to give it a large surface area for absorption of water and minerals into the cell., Adaptation: No chloroplasts due to being underground., Root Hair Cell, : Function of the sperm: To fertilise an egg cell., Adaptation: Long tail to help it swim to the egg., Adaptation: Lots of mitochondria to release energy to allow the sperm to move., Function of the egg cell: To be fertilised by a sperm cell., Adaptation: Cytoplasm contains nutrients for the developing embryo., Adaptation: Membrane changes after fertilisation to stop any more sperm getting in., Sperm Cell and Egg Cell - Sex Cells, : White Blood Cell, Function: To kill pathogens that cause disease., Adaptation: Produce antibodies to kill pathogens and antitoxins to neutralise toxins., Adaptation: Can change shape to squeeze out of blood vessels and engulf pathogens.,
