HORTICULTURE

Detailed explanation-1: -The pollen tube opens into the ovule through the micropyle and bursts into the embryo sac. Here, the male nucleus unites with the nucleus of an egg inside the ovule forming a diploid zygote, which later swells up and develops into a fruit.

Detailed explanation-2: -The term “fruit” is used for a ripened ovary. In most cases, flowers in which fertilization has taken place will develop into fruits, while unfertilized flowers will not. The fruit encloses the seeds and the developing embryo, thereby providing it with protection. Fruits are diverse in their origin and texture.

Detailed explanation-3: -In flowering plants after fertilisation, the zygote develops into the embryo, the ovules develop into the seed and the ovary develops into the fruit. Also, the sepals, petals and stamens of the flower generally fall off.

Detailed explanation-4: -The process of fertilization in plants occurs when gametes in haploid conditions meet to create a zygote which is diploid. The male gametes of the flower are transferred on to the female reproductive organs through pollinators. The final product of this process is the formation of embryo in a seed.
