In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).
Why do sperm have 23 chromosomes?
One set of 23 comes from mom and the other 23 from dad. The egg and sperm cells are an exception–they have only 23 chromosomes each. A sperm from the man combines with a woman’s egg in her womb to make a zygote. The zygote ends up with a total of 46 chromosomes and can now grow into a baby.
What are the gametes in plants?
In plants pollen grains contain the male gametes, which are made in the anthers. In plants the female gametes are called ovules and they are made in the ovaries. In animals male gametes are called sperm, which are produced in the testes.
