WebAug 19, 2024 · Spores - Reproductive Cells. Spores are reproductive cells in plants; algae and other protists; and fungi. They are typically single-celled and have the ability to develop into a new organism. Unlike gametes in sexual reproduction, spores do not need to fuse in order for reproduction to take place. Organisms use spores as a means of asexual ... WebThe multicelluar haploid stage (the gametophyte) produces gametes via mitosis which fuse to form a diploid zygote. The zygote develops into a mature multicellular diploid individual (the sporophyte), which produces haploid spores via meiosis. The haploid spores then develop into a mature multicellular haploid individual. highland local place plans

WebApr 11, 2024 · A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism. Search Get Updates WebIn animals, sexually reproducing adults form haploid gametes from diploid germ cells. Fusion of the gametes gives rise to a fertilized egg cell, or zygote. The zygote will undergo multiple rounds of mitosis to produce a multicellular offspring. The germ cells are generated early in the development of the zygote.
