Рубрика: 

microscopic reproductive bodies called spermatozoa (sperms is an accepted
abbreviation). The sperms have a single nucleus and a whip-like tail with which
they swim In the pond water when they are released.
You may also see hydra with a single large spherical swelling near the other
end of the body. This is an ovary and contains a single large egg swollen with
stored food. The egg, like the sperm, has a single nucleus, but it is much larger
owing to its food store and can be seen easily with the naked eye. The egg cannot
develop into a new hydra until it has first been fertilized by a sperm. Although
sperms and eggs are often produced by a single individual, they are never ripe at
the same time and so it is impossible for one hydra to fertilize its egg with one of its
own sperms.
