AP BIOLOGY

Detailed explanation-1: -After fertilization, the sepals and petals wither and fall off. The ovary develops into a fruit and the ovules form seeds.

Detailed explanation-2: -After fertilisation, the ovary grows into a fruit and other parts of the flower fall off. The fruit is the ripened ovary. The seeds develop from the ovules.

Detailed explanation-3: -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-4: -In mango and coconut, the fruit develop from monocarpellary superior ovaries and are one seeded.

Detailed explanation-5: -ovary, in botany, enlarged basal portion of the pistil, the female organ of a flower. The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself will mature into a fruit, either dry or fleshy, enclosing the seeds.
