How are gametes produced in plants? - Quora

WebGametes are formed through a process of cell division called meiosis. This two-step division process produces four haploid daughter cells. Haploid cells contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote. Continue Reading Catherine Hilliard WebApr 28, 2024 · Gametes are the physical carriers of genetic information from one generation to the next. They carry recombinant chromosomes produced at the end of meiosis. Often, species that reproduce sexually have two morphologically distinct types of individuals that produce different gametes. WebPlants use mitosis to grow as sporophytes, and to grow and produce eggs and sperm as gametophytes; so they use mitosis for both haploid and diploid cells (as well as for all other ploidies). In meiosis, the starting nucleus is always diploid and the daughter nuclei that result are haploid. population first ngo

"WebThe haploid multicellular plants (or algae) are called gametophytes, because they make gametes using specialized cells. Meiosis is not directly involved in making the gametes in this case, because the organism is already a haploid. Fertilization between the haploid gametes forms a diploid zygote.

WebImagine that we cross two pure-breeding pea plants: one with yellow, round seeds ( YYRR) and one with green, wrinkled seeds ( yyrr ). Because each parent is homozygous, the law of segregation tells us that the gametes made by the wrinkled, green plant all are ry, and the gametes made by the round, yellow plant are all RY.
