Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
If a cat has 38 chromosomes, how many chromosomes will each of the following cells have?
hair
claw
tounge
sperm
egg
It is given that the cat's cells have 38 chromosomes. There are found 19 pair of chromosomes in the cat's cell.
The diploid cells have two sets of chromosomes. Whereas haploid cells have single set of chromosomes.
Diploid cells have 38 chromosomes in cat cell. Whereas haploud cells have 19 chromosomes in cat's cell.
Here, hair, claw and tongue are diploid cells. That's why there are found 38 chromosomes.
Here, sperm and egg are haploid cells because they are produced by meiosis. That's why there are found 19 chromosomes.
