Detailed explanation-1: -The seeds and fruits are the results of fertilization or sexual reproduction in plants. The ovary in angiosperms develops into the fruit whereas the ovules become the seeds enclosed within the fruit. Seeds are found both in gymnosperms and angiosperms.

Detailed explanation-2: -Through the micropyle, the pollen tube enters the ovule and bursts into the embryo sac. Inside the ovule, the male nucleus joins with the egg nucleus to produce a diploid zygote, which eventually enlarges and transforms into a fruit.

Detailed explanation-3: -The class of plants known as flowering plants, or angiosperms, are those that produce both flowers and fruits. The name “angiosperm, ” which refers to plants that generate their seeds inside of a fruit, is derived from the Greek words angeion and sperma.

Detailed explanation-4: -Angiosperms are plants that produce flowers and bear their seeds in fruits. They are the largest and most diverse group within the kingdom Plantae, with about 300, 000 species. Angiosperms represent approximately 80 percent of all known living green plants.

Detailed explanation-5: -Ovule is the plant part that develops into a seed after fertilization. The ovules of angiosperms are contained in a structure called the ovary within the flower.
