Did you know?
WebDiploid multicellular organisms called “sporophytes” produce haploid spores by meiosis; the haploid spores reproduce by mitosis to produce multicellular haploid organisms called “gametophytes”. These haploid gametophytes then produce gametes by mitosis (because their cells are already haploid), and the gametes fuse to produce a zygote. WebNov 12, 2009 · The gametophyte is multicellular and mitotically produces gametes. In plants, the gametophyte nourishes the zygote and young sporophyte. germination -- The process by which a seedling emerges and develops from a seed, or by which a sporeling emerges and develops from a spore.
WebHAPLOID-DOMINANT LIFE CYCLE. In most fungi and algae the “body” of the organism – the ecologically important part of the life cycle – is haploid During sexual reproduction, specialized haploid cells from two individuals (+) and (−) mating types, join to form a diploid zygote immediately undergoes meiosis to form 4 haploid spores Although haploid like the … WebMany plants are, however, multicellular, that is their body is composed of numerous cells. Such multicellular body forms through the proliferation of cells. Imagine that the cells resulting from meiosis did not function as gametes, but instead remained vegetative. How would you develop a multicellular organism from these cells.
WebApr 28, 2024 · Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. There are over 300,000 species of plants; common examples of plants include grasses, trees, … WebAlternation of generations describes a life cycle in which an organism has both haploid and diploid multicellular stages (Figure 1). This type of life cycle, which is found in all plants, is described as haplodiplontic. Figure 1. Alternation of generations between the 1 n gametophyte and 2 n sporophyte is shown.
WebSep 22, 2024 · The haploid multicellular plants are called gametophytes because they produce gametes. Meiosis is not involved in the production of gametes in this case, as the organism that produces gametes is already haploid. Fertilization between the gametes forms a diploid zygote.
WebThe diploid stage is geared to the high mutation rate that terrestrial plants experience. Ferns contain flagellated sperm, which implies they rely on water to reproduce. Another explanation for sporophyte dominance is that ferns have vascular tissue and are considerably taller to moisten the ground.
