WebHigher plants (angiosperms) have a long-lived sporophytic generation that is the diploid sporophyte. The sporophyte is the growth you would easily recognize as a plant. Through the process of meiosis, the sporophyte produces haploid spores in the flower. The spores are the gametophytic generation. highland hospice houston txWebIf both male and female flowers are borne on the same plant, the species is called monoecious (meaning “one home”): examples are corn and pea.

WebInside the anther’s microsporangia, male sporocytes divide by meiosis to generate haploid microspores, which, in turn, undergo mitosis and give rise to pollen grains. Each pollen grain contains two cells: one generative cell that will divide into two sperm and a second cell that will become the pollen tube cell.

WebThe male and female gametophyte structures are present on separate male and female cones in gymnosperms, whereas in angiosperms, they are a part of the flower. Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.

WebCorrect option is A) The inner diploid sporogenous tissue of each microsporangium first undergoes mitotic divisions to increase the cell number and then differentiates into microspore/pollen mother cell. Being the product of mitosis in diploid cells, microspore mother cells are diploid i.e. carry two complete sets of chromosomes. WebPremise: Five to six percent of angiosperm species exhibit a dioecious sexual system, with unisexual "male" or "female" flowers borne on separate plants. The consequent need for inter-individual pollen exchange is a special challenge for taxa where pollen is the sole pollinator reward.

WebIn angiosperms, zygote is diploid while primary endosperm cell is triploid. Explain. Ans. A zygote is formed by the fusion of haploid male gamete with the haploid egg to form a diploid cell; whereas, primary endosperm nucleus (PEN) is formed by the fusion of haploid male gamete with two haploid polar nuclei, forming a triploid nucleus. Q. 41. WebThe angiosperm life cycle consists of a sporophyte phase and a gametophyte phase.
