Detailed explanation-1: -Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.
Detailed explanation-2: -A Spores. Spores are microscopic propagative bodies, with a single nucleus, whose primary function is plant dispersal and reproduction. Spores are produced by “lower” plants, which include mosses, liverworts, clubmosses (lycopods), horsetails, and ferns.
Detailed explanation-3: -A spore is a cell that certain fungi, plants (moss, ferns), and bacteria produce. Spores are involved in reproduction. Certain bacteria make spores as a way to defend themselves.
Detailed explanation-4: -Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores. Spore plants have a different life cycle. A parent plant sends out tiny spores containing special sets of chromosomes. These spores do not contain an embryo or food stores.
Detailed explanation-5: -Pteridophytes are vascular plants that produce spores, such ferns, horsetails, clubmoss, and spikemoss. Pteridophytes are distinguished from other spore-producing plants, bryophytes, by their vascular tissue. Their lack of seeds also distinguishes them from other vascular plants, such as gymnosperms and angiosperms.
