Why do nerve cells have dendrites?
They make connections to other nerves.
Why do nerve cells have an axon?
It carries the impulses from one place to another.
Why do nerve cells have nerve endings/synapses?
They pass impulses to other cells by producing transmitter chemicals.
Why do nerve cells have many mitochondria?
They transfer the energy needed for making the transmitter chemicals.
Why do muscle cells have many mitochondria?
They transfer the energy needed for chemical reactions.
Why do muscle cells have a store of glycogen?
It can be broken down and used in respiration to transfer energy.
Why do sperm cells have a long tail?
To allow the cell to move.
Why do sperm cells have a middle section full of mitochondria?
They transfer the energy needed by the tail to move.
Why do sperm cells have an acrosome?
It stores digestive enzymes which break down the outer layers of the egg.
