NEET BIOLOGY

Detailed explanation-1: -The ovary produces ovules internally. Through meiosis, ovules produce megaspores which in turn develops into female gametophytes. As a result, egg cells are produced.

Detailed explanation-2: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-3: -The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. Stigma: The part of the pistil where pollen germinates. Ovary: The enlarged basal portion of the pistil where ovules are produced.

Detailed explanation-4: -It is a tube-like structure in which connects stigma and ovary. The style is particularly crucial throughout the fertilization process because it not only generates the pollen tube but also prevents incompatible pollen from entering the ovary.

Detailed explanation-5: -Within the flower, sperm cells are produced by pollen at the tips of stamens, while egg cells develop in ovules, tiny structures embedded in the ovary at the base of the pistil.
