DENDROLOGY

Detailed explanation-1: -Sexual propagation involves the union of the pollen (male) with the egg (female) to produce a seed. The seed is made up of three parts: the outer seed coat, which protects the seed; the endosperm, which is a food reserve; and the embryo, which is the young plant itself.

Detailed explanation-2: -Explanation of the correct option: Sexual reproduction takes place in all flowering plants. Plants reproduce from seeds through the process of sexual reproduction. Pollination is the process by which the male gamete reaches the female gamete, and fertilization occurs.

Detailed explanation-3: -The process by which new plants grow from seeds is termed gemination. Germinated seeds grow into a new plant.

Detailed explanation-4: -Once pollen gets transferred to the stigma the male gametes from pollen grains release and fuse with the egg in the ovule to form a zygote. This process of fusion of gametes is called fertilization. The zygote thus formed, divides and develops into an embryo, and later into a seed. The ovary develops into a fruit.
