Question

Discharge of ovum or secondary oocyte from the ovary or Graffian follicle is called:

Options

A
Fertilization
B
Pollination
C
Follicle formation
D
Ovulation

Explanation

Ovulation is the process of release or discharge of ovum or secondary oocyte from the Graffian follicle after maturation of the Graffian follicle.

This should not be confused with fertilization which is the fusion of male and female gametes for zygote formation.

Fertilization refers to the fusion of a sperm cell with an egg cell (ovum) to form a zygote, which eventually develops into an embryo. It takes place in the fallopian tube after ovulation.

Pollination is the process by which pollen grains are transferred from the male reproductive structure (anther) of a flower to the female reproductive structure (stigma) of another flower, leading to the formation of seeds.

This option is not correct. Follicle formation refers to the development and maturation of ovarian follicles, which contain oocytes (egg cells). Ovulation is the release of a mature egg from a mature follicle.

This is the correct option. Ovulation is the process during which a mature egg (secondary oocyte) is released from the ovary and enters the fallopian tube. It is a crucial step in the menstrual cycle and is necessary for fertilization to occur.
