Solution

Sperm are motile because they have to travel inside the female reproductive system to reach the egg for fertilisation. Eggs, on the other hand, are considerably bigger than the sperm. They store food for the growing embryo.
The body cells (somatic cells) of humans are diploid cells and contain 46 chromosomes whereas the sex cells in humans are haploid and contain half the set of chromosomes, i.e., 23.
