Why the female gamete bigger than male gamete?

Answer 1

The female gamete is most likely bigger than the male gamete because it is the cell that will eventually provide the nutrients for the organism that will begin to grow there. It will start forming into a multicellular organism and therefore needs to be big enough to divide.

Answer 2

I personally think that there are several reasons for this:

1. During sexual intercourse, it is the male gamete which travels towards the female gamete, thus it is obvious that the male gamete has to be smaller than the female gamete.

2. There is normally only one female gamete present during a particular sexual intercourse compared to millions of male gametes. So as not to make wastage, the male gamete is smaller than the female gamete.

3. The female gamete contains food for the zygote after it has been fertilised and before it gets implanted in the wall of the uterus.

Answer 3

The usual case as found in humans is that single non motile egg is released by ovary during ovulation. The quantity of sperm produced is around 300 millions per ejaculate. The egg is a microscopic structure while sperm is an electron microscopic structure.

Answer 4

Generally in most of the organisms the Male gamets are motile and female are not.

So,male gamet has to reach the female gamet...during this travel some of them may die due to unusual exposour,thus produced in a large no.

Answer 5

In humans, the female gamete, the egg, is larger and singular (i.e. there is usually only one released at at time). The male gamete, the sperm, is relatively tiny and produced in the millions.

Answer 6
