Pollination in plants

Hello friends of Steemit, in this opportunity, I bring you an interesting topic, referring to the process of pollination in the plants. It is important to know how this natural pollination process is carried out, with the help of insects, animals, water and wind.

To speak of pollination, it is necessary to know the meaning of the term pollen. This refers to a "very fine powder" that is present in the stamens of the flowers, with this material the pollination process will be carried out. The Pollination, is defined as the process by which insects when they go from flower to flower, to extract the nectar, remain impregnated with the pollen, and transport it from the stamens of the flower until reaching the stigma or receptive part of the flowers, which is where the ovules of the flower germinate and fertilize, making possible the production of seeds and fruits, that is, the insect will combine the pollen of the male parts of a flower, with an egg (egg) of the female parts of another flower of the same type.

Insects and animals pollinators

Plants produce flowers to attract pollinators and do mating work for them. Pollinators can be bees, flies, beetles, moths, hummingbirds, bats and other animals that visit flowers. These insects go from one flower to another, to collect nectar and pollen to feed or feed their young and at the same time the flowers are pollinated.

When is the flower pollinated?

The flower is pollinated when a grain of pollen falls on the stigma. If the pollen comes from a plant of the same type, the granite cover opens, then from its interior a tube grows, passes through the style and goes to an ovule; When the tube has stopped growing, a male sex cell that fertilizes the ovum and leaves it.

Other forms of pollination

Some angiosperms are pollinated by the wind (anemophilous plants) and generally occur in those plants whose flowers do not have aromas and produce pollen quantities that are blown by the wind. Other forms of pollination are carried out by some animals (zoophilous plants), and they are flowers with bright colors and a pleasant aroma that attract the animals that are going to pollinate them, in this case there is a plant-animal relationship that is mutualistic, that is, a relationship in which both benefit. Pollination also occurs through water (hydrophilic plants).

Pollination by the wind, in pine plants:

SourceApple and cherry are fruits, there are others like tomatoes and cucumbers that you might think are vegetables. But the next time you eat a fruit try to identify its envelope and the mature ovary.

I have elaborated this topic in a simple way, so that the students can understand this interesting natural process of pollination.
