NEET BIOLOGY

Detailed explanation-1: -Spermatogenesis and oogenesis are both forms of gametogenesis, in which a diploid gamete cell produces haploid sperm and egg cells, respectively.

Detailed explanation-2: -Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

Detailed explanation-3: -Gametogenesis is the production of gametes from haploid precursor cells.

Detailed explanation-4: -During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes. Hence, in animals, meiosis is an integral part of gametogenesis. In plants, some fungi, and some algae, meiosis is temporally separated from gametogenesis.

Detailed explanation-5: -The development of diploid cells into gametes is called gametogenesis. It differs between males and females. A gamete produced by a male is called a sperm, and the process that produces a mature sperm is called spermatogenesis.
