DENDROLOGY

Detailed explanation-1: -Flowers are special structures that help flowering plants make more plants. In order to make more plants, pollen must move from the male part of a flower to the female part of a flower, and then the pollen tube must grow to the ovary to make a seed.

Detailed explanation-2: -Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary, which usually ripens into a protective FRUIT. Gymnosperms (conifers, Ginkgo, and cycads) do not have flowers or ovaries. Their seeds mature inside cones.

Detailed explanation-3: -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-4: -The term “angiosperm” is derived from the Greek words (’container, vessel’) and (’seed’), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13, 000 known genera and 300, 000 known species.
