Oogamy is a type of reproduction in which male and female gametes are produced in different organisms. In this case, male gametes are called sperm, and female gametes are called eggs.
Oogamy is the most common type of reproduction in animals and plants. It is also found in some bacteria, fungi and protozoa.
In oogamy, female gametes (eggs) mature inside the female reproductive organs, such as the ovaries in animals or the oviducts in plants. Male gametes (sperm) mature in the male reproductive organs, such as the testes in animals or the anthers in plants.
After the gametes mature, they move to the corresponding reproductive tract - the ovary (female) or the vas deferens (male). Fertilization occurs here, in which the male gamete merges with the female one.
The result of this process is a zygote, a new cell that contains genetic material from both parents. The zygote begins to divide and grow, forming a new organism - an embryo.
Thus, oogamy ensures the transfer of genetic information from parents to offspring. It also contributes to the diversity of the population's gene pool due to the possibility of crossing different species.
