Gamete The male or female single celled haploid (1 n) units of sexual reproduction. Gametophyte The multicellular, haploid (n) phase of the alternation of generations, which produces male and/or female gametes by mitosis. Haploid A cell having only one compliment of chromosomes. ...
The role of the male gamete, although studied structurally for over a century at various levels, is still being explored on a molecular and cellular level. The potential of the male to influence development has been historically underestimated and the reasons for this are obvious: limitations ...

chemicals (EDCs) can interfere withendocrine system, resulting in changes in levels ofreproductive hormones. The above factors primarily target the hypothalamic–pituitary–gonadal (HPG) axis disrupting thespermatogenesis, which is the essential process associated with the development of the malegamete. ...

3. Definition of Gametophyte: - The gametophyte is the haploid phase of the plant life cycle responsible for the production of gametes (sperm and eggs). In Selaginella, the male gametophyte is also haploid. 4. Identify the Vegetative Structure: - The vegetative part of the male gametophyte in...
Reproduction in the egg laying mammals is considered particularly to understand the genes involved in lactation, testicular descent, gamete biology including fertilization, and early development. Their spermatozoa are sauropsids-like and lack the stiffness and velocity of eutherian and marsupial spermatozoa...
