Features of Sexual Reproduction
Two parents are involved (both male and a female).
Gamete formation and fertilization takes place.
The whole process is slow and lengthy.
The variation occurs; offspring are different from parents, genetically and physically.
Sexual Reproduction in Plants
Reproduction in plants takes place sexually and asexually as well. But the majority of the flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male and female gametes are produced by flowers. Sexual reproduction in plants takes place in flowers. The complete flower typically consists of four parts:
Petals
Sepals
Stamen (male reproductive part)
Pistil/Carpel (female reproductive part)
Stamen (male reproductive part) consists of anther and filament.
The anther is a sac-like structure that produces and stores pollen.
The filament supports the anther.
Pistil (female reproductive part) comprises of three parts- stigma, style, and ovary.
Stigma is the top most part of a flower.
The style is the long tube which connects stigma to the ovary.
The ovary contains a lot of ovules. It is the part of the plant where the seed formation takes place.
In plants the male reproductive organs the stamen ( filament and the anther) produces a yellow color powder, the pollen grains which sticks on the sticky stigma, stigma is a part of Style, the female reproductive organ. The pollen grain, the male gamete travels through the style to the ovary. Fertilization of the egg occurs and slowly it forms a zygote.
