what is spermatogenesis and oogenesis

Production of offsprings by a single parent without the formation of gametes is called asexual reproduction. It is also called as somatogenic reproductio..

Spermatogenesis - The process of spermatogenesis occurs in the seminiferous tubules of the testes. The whole developmental process of proliferation of spermatogonia or the sperm mother cells to mature spermatozoa or sperm is called as spermatogenesis. The functional sp..

Sexual reproduction involves the fusion of two haploid gametes to form a diploid individual. The process by which gametes are produced in the gonads is known as gametogenesis. Gamete formation starts at puberty, an average of 9 - 11 years in girls and 11 - 13 years in boys. It is of 2 types. S..

Question: The process by which the sperms are produced is known as ____________. 1. ovulation 2. spermatogenesis 3. oogenesis 4. gestation Answer: ..

Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells . In unicellular organisms like the protozoans, the gamete-producing individuals are called gametocytes. The gametes may be similar - isogametes as in Monocystis or ..

Animals may reproduce by asexual and sexual modes. The reproductive system of sexually reproducing animals consists of primary sex organs which produce the gametes, the secondary sex organs which participate in reproduction but do not form gametes and accessory sex characters which distinguish the ..

Each diploid primary spermatocyte undergoes meiosis I, which is a reduction division. Two daughter cells are formed each with 'n' number of chromosomes. The daughter cells are called secondary spermaotcytes. The secondary spermatocytes are haploid and much smaller comparitively, containing (22+X) o..

) from which they obtain their nourishment. Spermatogenesis is controlled by FSH (follicle stimulating hormone) and the gonadotropins. In man, there are two types of sperms produced. 50% of the sperms have the X chromosome and are called as gynosperms. 50% of the sperms have the Y chromos..

>seminiferous tubules and the interstitial cells between the tubules. Longitudinal Section Showing LobulesContaining Seminiferous Tubules The seminiferous tubules produce sperms that are passed along the tubules to the posterior region of the testis. The sperms are produced by a process called the ..
