In general, this is the main group of unicellular organisms. Constantly opening up new types of plants.
How many plants on earth
Today, the plant kingdom includes more than 300 thousand different species. Distinguish them based on the characteristics of the life cycle and features of existence. If you take life forms, then the plants are shrubs, trees, herbs, according to the method of reproduction - seed and spore, for the duration of existence - annual, biennial and perennial. The plants include some species of algae, moss, horsetails, mosses, ferns, gymnosperms and flowering plants.

Proceeding from the fact that they die easily, their numbers decrease and they are entered into the Red Book.
Significance of the plant world
One of the most basic environmental problems is closely related to the protection of plants and the preservation of the green layer of the planet. Without a plant species, the existence of animals and humans is impossible.Plant organisms absorb CO2 from the atmosphere and emit O2, thereby purifying the air, making it more conducive to breathing. Plants are one of the main types of food for heterotrophic organisms, including humans. What types of plants are key in the life chain, can be listed indefinitely, because they are used in various spheres of life.
Therefore, many organizations are being created today that are fighting for the safety of the green world and constantly urge all of humanity to actively participate in improving the state of the planet.
