DENDROLOGY

Detailed explanation-1: -Seeds are surrounded by one or two integuments, which develop into a seed coat that is usually hard. They are enclosed in the ovary of a carpel and thus are protected from the elements and predators. The ovule is attached to the ovary wall until maturity by a short stalk called the funiculus.

Detailed explanation-2: -The function of the fruit is seed dispersal. They also protect the developing seed. Different fruit structures or tissues on fruit-such as sweet flesh, wings, parachutes, or spines that grab-reflect the dispersal strategies that help spread seeds.

Detailed explanation-3: -The success of angiosperms is due to two novel reproductive structures: flowers and fruit. The function of the flower is to ensure pollination. Flowers also provide protection for the ovule and developing embryo inside a receptacle. The function of the fruit is seed dispersal.
