How are male gametes formed
WebAsked By : Joseph Anderson. Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote. WebCorrect option is D) In the pollen tube, the body cell divides into two unequal cells, the male gametes or sperms. The sperms are non-motile and are formed only one week before fertilization. Non-motile sperm is an advanced character in Pinus. Was this answer helpful?

WebSolution. In flowering plants, a single pollen particle produces two male gametes. At the two-celled stage, pollen grains are discharged from pollen-sacs, where the generative cell divides further to generate two male gametes. The embryos are subsequently discharged into the sac. They combine with female gametes to produce an embryo (egg) and ... WebOutcrossing populations must therefore produce many more male gametes than the number of available female gametes (eggs or ovules). By contrast, the male gametes of …

In mammals, gametes are produced in the testes or ovaries of individuals but anthers and ovaries are on the same flowering plant. WebSexual reproduction. Like all animals, corals reproduce sexually. There are male polyps that produce male gametes (sperm) and female polyps that produce female gametes (eggs). Corals that live in a colony can have both males and females in the same colony, so the coral is said to be hermaphrodite. The fertilization that takes place during the ...
WebCorrect option is B) The pollen grain is the male gametophyte. The cell in the pollen grain divides unequally to form two cells called as tube cell and generative cell. The tube cell provides nourishment. The generative cell divides to form the two male gametes. These two male gametes travel along with the pollen tube towards the female ...
