In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [1] . Spores form part of the life cycles of many plants, algae, fungi and protozoa. [2] .

spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores thus differ from gametes, which are reproductive cells that must fuse in pairs in order to give rise to a new individual. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction.

Spores are the reproductive structures that helps in reproduction of many plants, bacteria and fungi. These exist in variable shapes, sizes and number. Spores are of mainly two types: endo and exospores based on their origin.

2023年11月21日 · Spores can be formed inside fruiting bodies or the mother cell. The role of spores is reproduction and survival. Spores can be classified based on motility, fruiting bodies, sporogenesis,...

2024年5月21日 · A spore is a unit of asexual reproduction adapted to spending a long period of time in unfavorable conditions before developing into an offspring of the plant, algae, fungi, or protozoan that created it. They are somewhat like seeds, but contain fewer nutrients, and are used by groups besides plants.

Spores are the way fungi and some non-seed plants (ferns and mosses) reproduce. [1] [2] They are also made by bacteria for long-term survival. Some protozoa also make long-term survival spores. The spores of seed plants are single cells that grow into a pollen grain or the gametophyte inside the ovule.

2023年2月2日 · Sporulation or spore formation is the process of producing spores from the actively dividing (vegetative) cells. They are commonly found in bacteria, fungi, protozoa, and some plants such as ferns and mosses. The term ‘spore’ comes from the Greek word for seed.

Among plants, spores are the reproductive agents of asexual generation. They are produced by the sporophyte generation and give rise to the gametophyte (gamete-bearing) generation. Spores are most conspicuous in the seedless plants, a group that includes liverworts, mosses, and ferns. The spores are carried in cases called sporangia.

This guide dives into the definition of spores, their crucial role in reproduction and dispersal, and the different types found across various organisms. Read on to learn how spores ensure survival.

Spores are unicellular and haploid (having one-half of the genetic complement as have somatic, or body, cells). They are produced by meiosis in the sporophyte, a structure whose cells have a full complement of chromosomes (usually diploid) and generates the spores.
