One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
The act or process of initiating biological reproduction by insemination or pollination. The union of male and female reproductive cells (gametes) to produce a fertilized reproductive cell (zygote). Fusion of a sperm cell with an egg cell to produce a zygote when the female sex cell (egg) and the male sex cell (sperm) come in contact. the joining of a sperm and an egg The fusion of the male sex cell with the female sex cell to form an embryo is called fertilisation. The fusion of an egg and sperm to form a zygote
Another word for sex cells is gametes. A male and female gamete come together to form a zygote: the first cell of the new organism.
When male and female plant reproductive cells join, a zygote will form. This zygote will eventually develop into a new plant organism through cell division and growth.
Only one sperm cell fertilizes the female egg during sexual reproduction. The sperm cell contains genetic material from the male that combines with genetic material from the female to form a new individual.
Actually, the cell theory stated by Schleiden and Schwann consists of three main principles: all living organisms are composed of cells, the cell is the basic unit of life, and all cells come from pre-existing cells. Membranes are essential components of cells, but they are not the sole basis of cell structure according to the cell theory.
Both systems produce cells called gametes that has half the number of chromosomes as body cells do. One is called a sperm cell and the other is the egg. They both must come together to form a cell called a zygote that will form a new individual.
Meiosis is purely for the production of sex cells. When one cell undergoes meiosis, it turns into ethier 4 sperms cells for a male or 3 extra cells and 1 egg cell for a female.

As you may know, almost all our cells contain pairs of chromosomes - 23 pairs to be exact. These are called diploid. Haploid cells contain only one chromosome from each pair. Reproductive cells (both male and female) are haploid, so they can fuse and form a diploid cell with chromosomes from both the male and the female. The female reproductive cell (which is haploid) is the ovum, or egg cell.
Another word for sex cells is gametes. A male and female gamete come together to form a zygote: the first cell of the new organism.
What says that all living things are made of cells, that cells can divide to form new cells, and that all cells come from other cells?
When male and female plant reproductive cells join, a zygote will form. This zygote will eventually develop into a new plant organism through cell division and growth.
