what are spores ?explain in detail


  • Spores are reproductive structures which can germinate and give rise to a new life.
  • They need not fuse with other reproductive cells.
  • Several non flowering plants, fungi, bacteria, protozoa etc produce spores as a means of reproduction.
  •  Spores are formed both asexually and sexually.
  • Spores sometimes are very hard and may survive for years.
  • Unlike seeds, spores do not contain any food or resource, thus they are not eaten up by animals or insects.

 Spores are the reproductive cells for fungi and ferns. They are small and light weight so that they can easily be carried by the wind.
In, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. A chief difference between spores and seeds as is that spores have very little stored food resources compared with seeds.

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 used most frequently by r-selected species — that is, species whose evolutionary strategy is quick reproduction and high reproductive rate rather than quality of each individual. Such species do best when environments are unstable and rapidly changing, though they also exist in stable environments.
