The vegetative ones have a number of defining traits that we can remember from biology textbooks, where there were detailed descriptions of species.

Undetermined growth. Some varieties have indeterminate growth, up to and including death. This applies to perennial plants. While certain organs in plants have deterministic growth, there is no period of negative growth.
Fixed lifestyle. The fixed lifestyle is characteristic of plants, due to the way they absorb moisture and obtain nutrients. It is through the roots that water penetration occurs. In order to put down roots, it needs to establish itself in the soil.
Photosynthesis. The ability to absorb carbon, sunlight and produce the oxygen that humans need.
Feed on dissolved inorganic substances by absorption. Starch as the main nutrient.
Cell Structure. Has a special cell structure. There are no centrioles, the cell wall is made of cellulose, and includes green plastids, as well as a large central vacuole surrounded by a tonoplast.

Among the variety of species, two main classifications can be distinguished:

Vascular. There are organs, special tissues, and vessels through which mineral salt dissolved in water moves, as well as sieve-like tubes that conduct organic matter.

Nonvascular. Consists of xylem and phloem. Possess simple tissues with a special function for the internal transport of water.

Basic species
The plant kingdom can be divided into two main groups: higher and lower. The lower ones have no organs and tissues, while the higher ones have both.

The lower ones include algae: green algae, brown algae and red algae.

The higher ones are divided into spore and seed algae. Spore plants include mosses, ferns, horsetails, and clay plants. Seminal: Holosperms, coatsundews.

The lower ones tend to live in water. And the higher ones need developed tissues just to get minerals from the soil and to carry out photosynthesis. With special cells, tissues, and organs, plants have mastered different habitats, and some have even returned to water.
