Only one sperm fertilises an egg in normal cases, abnormally there are chances of fertilization by 2 or more sperm cells but such a zygote usually does not survive.

How many sperm cells enter the plant ovule?

Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.


How many sperm cells are produced in males when one diploid cell enters gametogenesis?

One diploid cell entering gametogenesis will undergo meiosis and produce four haploid cells, each of which will develop into a sperm cell. Therefore, one diploid cell entering gametogenesis will result in the production of four sperm cells.


How many sperm cells are necessary to chemically break down the egg cell wall?

Multiple sperm cells are involved in the process of fertilization, but only one sperm cell is needed to penetrate and fertilize the egg cell. Once the sperm cell penetrates the egg, it releases enzymes that break down the egg cell wall, allowing the genetic material of the sperm to enter the egg.


Has how many chromosomes withn the egg cells?

All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.


During spermatogenesis a cell with 2n chromosomes divides to form four sperm cells. How many chromosomes are in each sperm cell?

Each sperm cell will contain n chromosomes, which is half the number of chromosomes in the original cell.


How many sex cells are made from one reproductive cell?

In humans, one reproductive cell (sperm or egg) gives rise to four sex cells (sperm or egg) through the process of meiosis.


If a heart cell has 30 chromosomes how many chromosomes do a sperm cell of the same organism have?

15. A sperm cell is an example of a haploid cell. Two haploid cells combine to form a diploid cell, of which a heart cell is an example.
