Gametes

Once a year, on cues from the lunar cycle and the water temperature, entire colonies of coral reefs simultaneously release their tiny eggs and sperm, called gametes, into the ocean.

In ways that scientists still do not fully understand, mature corals release their gametes all at the same time. This synchrony is crucial, because the gametes of most coral species are viable for only a few hours. The “blizzard” makes it more likely that fertilization will occur.

The gametes produced by the male are motile.

Moss have motile sperm, unlike most plants, who take advantage of their surroundings to transport their gametes.

Reproduction is asexual when there is no fusion of gametes.

Benedito has male reproductive organs and male gametes.
