Gametophyte dependent on sporophyte
WebJul 21, 2024 · Is gametophyte dependent on sporophyte in gymnosperms? In gymnosperms and angiosperms, the gametophytes are dependent on the sporophytes in order to reproduce. Gymnosperms are plants that do not produce flowers but instead generate cones and seeds. Angiosperms are vascular plants. They are composed of a … WebCorrect option is A) Bryophytes are non-vascular terrestrial plants of moist habitats in which a multicellular diploid sporophyte lives as a parasite on an independent multicellular haploid gametophyte that develops multicellular jacketed sex organs.
Gametophyte dependent on sporophyte
Did you know?
The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a … See more A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase. See more Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, … See more Alternation of generations See more • Kenrick P, Crane PR (September 1997).

S2CID See more The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, … See more During the Devonian period several plant groups independently evolved heterospory and subsequently the habit of endospory, in which the gametophytes develop in miniaturized form … See more WebMar 31, 2024 · In most vascular plants, however, the gametophyte is dependent on the sporophyte. In bryophytes the long-lived and conspicuous generation is the gametophyte, while in vascular plants it is the sporophyte.
WebSolution. The correct option is A Bryophytes. Sporophyte is either completely (or) partially dependent on gametophyte in bryophytes. Suggest Corrections. 2. WebThe sporophyte is attached to and dependent on the gametophyte. (By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid …
WebAll conifers share a typical seed-plant life cycle with a long-lived, dominant, photosynthetic, diploid sporophyte and a reduced, transient, dependent, haploid gametophyte. All phases of this general life cycle vary among …
