Detailed explanation-1: -Egg cell is the female haploid gamete. It is enclosed in ovule which in turn present in an ovary of a flower.

Detailed explanation-2: -Development of sperm and egg cells in plants Within the flower, sperm cells are produced by pollen at the tips of stamens, while egg cells develop in ovules, tiny structures embedded in the ovary at the base of the pistil.

Detailed explanation-3: -The eggs are stored within follicles in the ovary. Within a woman’s lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process.

Detailed explanation-4: -Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.

Detailed explanation-5: -Each ovule contains an egg. 1 Pollen grains land on the stigma and begin to grow pollen tubes. Sperm cells within the pollen grain move down the pollen tube and into an ovule. Fertilization occurs as one of the sperm cells fuses with the egg inside the ovule.
