NEET BIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Ovule is also known as megasporangium. Female gametophyte is embryo sac which is haploid.

Detailed explanation-3: -Ovary is the female reproductive part of a flower and ovules are located inside the ovary. Ovary after fertilization turns into a fruit whereas ovules turn into seeds of fruit. An ovule is a structure found inside the ovary of plants. Integuments are the two layers which cover the internal structures of the ovule.

Detailed explanation-4: -Thus, in angiosperms (flowering plants) and gymnosperms (plants with “naked seeds”), the male structures produce pollen (which contain sperm), and the female structures have one or more ovaries (which contain eggs known as ovules).
