Where does meiosis take place in plants and animals?
Many plants are monoecious, meaning they have both male and female reproductive organs on the same plant. In these species, meiosis happens in the anther, which is a small structure containing male gametes. Other plants have separate male and female flowers on the same plant. In these species, meiosis happens in the pollen grain.
Where does meiosis take place in animals?
The location of meiosis in animal cells varies among species. In some species, meiosis occurs within the egg itself. In others, it occurs in the developing embryo, or in the sex cells that will eventually fuse to form the zygote. In humans, meiosis begins in the oocyte (or egg cell) when it is first created, usually during puberty. The chromosomes then undergo a second division, forming an equal number of chromosomes from each parent. This division results in the production of
Where does meiosis take place in humans?
During meiosis, a single cell divides to form two daughter cells with half the original number of chromosomes. In humans, meiosis occurs in the female and male germ cells. In the female, meiosis occurs in the ovaries. After puberty, the ovaries start to grow and will eventually produce eggs. In the male, meiosis occurs in the testes. Sperm cells, which are the male sex cells, are produced by meiosis.
Where does meiosis take place in humans body?
Meiotic divisions happen in the sex organs of the males and females of the species—in the ovaries and testicles in humans. They take place in the developing embryo, at the beginning of sexual development. The process is unique in that it involves two rounds of cell division to produce four genetically distinct daughter cells.
Where does meiosis take place in plants?
In plants, meiosis takes place in the male and female gametophytes. These are the developing gametes that form inside the anther and ovule, respectively. In bisexual plants, the male and female gametophytes are genetically distinct and develop in different structures. In self-fertilizing plants, a single embryo forms within each ovule and eventually becomes the seed.
