Question

In flowers, the portion of the carpel in which the egg-containing ovule develop is
A. Stamen
B. Pistil
C. Ovary
D. Stigma

Answer 1

The plants reproduce both by sexual and asexual reproduction. In plants, it is called vegetative propagation and the reproduction happens by vegetative parts like stem, root, and leaves. For sexual reproduction, the fusion of male and female gametes are essential.

Complete answer:
In plants, flowers are the organs of sexual reproduction. The process of production of new plants by the fusion of male and female gametes is called sexual reproduction. There are several steps for sexual reproduction in plants. In flowers, male and female reproductive organs will be present either in the same flower or in different flowers. Male reproductive organs in a flower are called Androecium and female reproductive organs are called Gynoecium. Androecium consists of stamens and gynoecium consist of carpels. Stamen contains anther and filament. Inside another, pollen grains are formed by a process called microsporogenesis.
The gynoecium consists of carpels and it together forms a pistil. The pistil consists of several parts like stigma, style, and ovary. The ovary is the place in which the development of the egg takes place.
Pollination is the process of transferring pollen grains from the anther to the stigma. After pollination, the pollen tube is formed from the pollen grains that lead male gametes towards the ovule. It is inside the ovule the process of fertilization takes place. Fertilization is the process of fusion of male and female gametes. Male and female gametes are fused to form a structure called the zygote. The zygote is diploid whereas male and female gametes are haploid structures. Know that the zygote gradually develops to form an embryo. This process is called embryogenesis. The embryo develops inside the seed and it germinates to form a plant.
Hence, the correct option is C.

Note: Note that although seed is considered to be a product of sexual reproduction after fertilization, seeds are also made without fertilization. The process is called apomixis and the seeds thus formed are called apomictic seeds.
