a man can release millions of sperm at once,however only one sperm can fertilize an egg
Think about it. Sperm is just the single swimming cell with the chromosomes. Semen is perm mixed in with liquid. The seminal vesicles and prostate gland produce the liquid that provides the sperm with a proper environment in which to swim in to fertilize the egg. So yes they are very important.
I think that the answer to your question will be determined by the perspective of why you may think that there are more sperm produced than needed. Nature has a way of being very economic with her use of resources. There is a concept in Modern Western Science called entropy, which basically states that processes in physics, or in nature, genreally tend to try and find their lowest state of energy. So the question of why males produce millions of times more sperm cells than was needed to fertilize just one egg is a really good one, because it means there is something about nature that we may yet not understand. My answer would be that there is an element of uncertainty in the natural world, and in order to increase the odds of fertilization, the male needs to expend a large amount of energy to be reproductively healthy. And that means making lots of sperm with lots of chances to beat the odds of missing that one tiny little target. sperms do not live long (only about 48 hours); but because there are so many of them, some are able to reach the egg to fertilize it.
Well, all plant cells have a cell wall. (I think. . .)
I think you are referring to a gamete, which can be a sperm cell or an egg cell.
An egg gets fertilized when a sperm from the male is allowed through the egg membrane and mixes its chromosomes with those of the egg from the female. With many egg producing creatures in the oceans, rivers, and lakes, the males and females release their eggs and sperm at the same time and they make the water cloudy. Some amphibians release their eggs and sperm from the leaves of trees and they drop in the water together. Some animals use internal fertilization. With birds and reptiles, the eggs are fertilized inside the female before the hard shell forms. Other beings that fertilize their eggs internally give birth to live babies.
I am not sure. But i think you can. But your sperm aren't active. Which means they are not able to fertilize an egg.
I think that the pollen grains is neede to fertilize the carpel.......

I think you're talking about semen? It's the cells that fertilize the female cell during intercourse. It's full of sperm, but only one meets the cell and creates a baby. Need I say more?
Amphibians fertilize their eggs externally.
i think.. millions of millions...
I think no
sperm or male reproductive cells.
The answer is 9 cm.
No. Male frogs externally fertilize the females eggs.
