What are spores?

Spore is a unit of asexual reproduction adapted to digestion for a long time in unfavorable conditions before developing plants, algae, mushrooms or protozoans that created it. They are somewhat like seeds, but contain fewer nutrients and are used by groups except plants. Spores are most commonly used by the types of selected R-TJ. A species whose evolutionary strategy is rapid reproduction and high reproductive speed rather than the quality of each individual. Such species are best when the environment is unstable and changes rapidly, although they also exist in a stable environment. Can be contrasted with gametes; While gametes (as human eggs and sperm) must be combined with another gamete to form individuals, disputes must connect with anything and can grow independently in an adult organism if conditions are appropriate. Disputes are unicellular, measurements between 4 and 20 micrometers (microns) size. In the process of dividing cells between the stadium of the spore and the adult phase, the weight and volume ofRganism to increase by a factor of millions or trillion. Large ferns can have dozens of trillion cells.

In everyday experience, spores are most associated with mushrooms, especially mushrooms and forms. One sponge can release millions or billions of spores, as the only drop of human ejaculate contains millions of sperm. As for reproduction in nature, redundancy is a good thing. Smaller organisms that release them, such as unicellular fungi, algae and protozoans, release less, little as one by one. Many organisms that release spores and asexually reproduce also have the ability to reproduce sexually, making them release gametes. Gamets are similar, but only half the genome - they require others to create a full genome. In the mushrooms, gametes are sometimes also referred to as disputes.

the earliest land plants reproduced exclusively through disputes as well asThe descendants today. These are called seeds and include hornbeats, liverworts, mosses, ferns, ferns, clubs, and several extinct groups. In addition to the presence or absence of vascular tissue, another primary feature is used to classify plants, whether they are reproduced by this method or not. The earliest plants using spores developed about 470 million years ago, in Ordovik. Their fossilized spores are the oldest example of multicellular life on Earth.
