Division Equational

Equational division

Equational division is one of the types of plant propagation in which the seeds ripen inside the fruit and are separated from it after fertilization. This process is important for plant seed dispersal and maintenance of plant populations.

History of equational division

The first information about the process of equational division was obtained in ancient civilizations such as Ancient Egypt, Ancient Greece and Ancient Rome. In these civilizations, people used the fruits of plants such as melons, pumpkins and peppers to store their seeds. As people evolved, they began to realize that the seeds inside fruits often reached maturity and could be used to propagate plants. It is from this moment that the process of division by equation begins to be used for the preservation and propagation of plants.

The mechanism of equational division. The process of equational division usually involves two main components - the fruit and the seed. The fruit of different plants can be different and have different shapes and sizes. For example, walnut fruits are spherical, and apple fruits are pear-shaped or round. However, the general mechanism of equivalence division remains the same for all plant species. During the development of the fetus, it accumulates nutrients that are necessary for the growth and development of the seed. These nutrients are stored inside the fruit and the seed only gains access to them once the fruit is ripe and soft. The equatorial division process continues after the fruit has begun to decompose and lose its hardness. At this point, all the nutrients and minerals collected in the fruit are available for the growth of the seed inside the fruit. The seed begins to grow and develop, absorbing all the nutrients from the fruit. When the seed reaches its maturity and

Equational division is a division in which the germination of pollen grains (in angiosperms) occurs during the growth of the dough (testal) to the upper part of the placenta (on part of the stem).

Division by equation occurs in angiosperms and ensures a more uniform distribution of fruits and seeds after the plant falls. Test germination helps prevent uneven seed germination, which is often observed with placental or maternal divisions. This is because the germination of all the seeds in one area of ​​the placenta can lead to a denser colonization of the environment, where few plants will leave fruits, and this will lead to excessive growth of a certain group of species, which will entail competition between them. Also, such uneven development contributes to the fact that less adapted species can be replaced by more adapted ones, and thus reproduce, therefore leading to a decrease in evolutionary opportunities.

Test division also occurs due to changes in temperature at the site of placental attachment or fetal development. When the testa matures, the embryonic root begins to expand and grow towards the top of the placental cole or bark of the plant, called the "basket" (later called the sullus cole), and ending in the covering leaf; in this case, the formation of embryonic roots with two ends is possible. Because the growing sprout has a positive entropic effect, a somewhat unstable level of energy is maintained below and above the test site, causing growth. The short tubular layer is called the guard layer, which provides additional strength to the germinating pollen grain. This protective layer tends to separate into two longitudinal sections known as fraccularia, which unchain the pollen so that the pollen grains can germinate. Some investigators believe that cleavages occur by detachment from the testula under very slight internal pressure as the testula grows and reaches the apoplasmic membrane in the center of the main lamina, while
