DENDROLOGY

Detailed explanation-1: -A seed is formed when a pollen grain lands on the stigma of the flower, and sends down a pollen tube which releases a sperm cell into the ovule. This fertilization or joining of the sperm cell and ovule forms a cell called a zygote. The zygote then develops into an embryo.

Detailed explanation-2: -A seed is formed when fertilised ovule divides by mitosis. It stores food and has the potential to develop into a new plant under optimal conditions. Fertilization is the process of fusion of male gamete and female gamete to form a zygote.

Detailed explanation-3: -The product of sexual reproduction are seeds. Seeds produced through fertilization contain genetic material from both parents. As a result, the offspring are not genetically identical to either of the parent plants. This genetic diversity can help them survive if the environment changes.

Detailed explanation-4: -Flowers are the reproductive part of most plants and they produce seeds. Flowers contain pollen and tiny eggs called ovules.
