Why does a sperm cell contain large amounts of mitochondria?
ATo synthesise the cell wall surrounding the sperm, though sperm, like other animal cells, have no cell wall
BTo store food reserves for the developing embryo, a role instead carried out by the yolk in the egg cell
CTo produce energy required for the motility (swimming) of the sperm
DTo produce haemoglobin for oxygen transport, a role carried out by red blood cells, not sperm
Explanation
Mitochondria produce the energy needed for sperm motility.
