Many times it is possible to get lost within the different Plants types that exist on our planet. Therefore, in this Green Ecologist article, we want to teach you the basic divisions that you can find within this wide realm. Divided into large blocks we will explain the most important differences between the different kinds of plants so that you can recognize and classify them without any difficulty.

What types or classes of plants exist - basic classification

Recent studies have managed to catalog more than eight and a half million species of plants. Even so, there are many Plants types that have not yet been fully discovered, marine plants being the most unknown.

There are a wide variety of types of plants. Trees, palms, conifers, herbaceous, shrubs, mosses, ferns, algae and cacti among others. Each of them with its own characteristics that make them unique species. And although they have in common their system of obtaining energy through photosynthesis, we can classify them into large blocks that differentiate them.

They can be followed different plant classification criteria What:

  • Size
  • Reproduction
  • Time or duration

Others may be your food source, your location, and so on.

Classes of plants according to their size

One of the ways to classification of plants The most common is the one that orders them by kinds of plants according to their size:


In this group are the plants whose stems do not come to conform as a solid structure or woody type. So its consistency is much softer in general. These can be branched or unbranched. Generally their duration is short, but thanks to this they are plants with a superior adaptation to the climate. Hence, they are the most widespread on the surface of the planet.

In this other Green Ecologist article we will tell you more about Herbaceous Plants, their characteristics and examples.

Shrubs or subshrubs

Woody stem plants whose height does not exceed one meter. They are usually low-stemmed and usually live for several seasons.


They are woody plants, generally of the perennial type, that have multiple roots and a height greater than that of the bushes, reaching about three meters in height. Unlike trees, shrubs branch directly from the base.


Finally, there are the trees that are the largest plants. These have a woody trunk that begins to branch off at a certain height from the ground. Its average height is around five meters high. They are much more long-lived than other plants and can live for several centuries.

Kinds of plants according to their reproduction or if they have flowers

Flowers are the reproductive organs of plants. Depending on whether or not they have them, the classification of plants It occurs in two large groups:

Plants with reproduction by spores

Here are bryophyte plants and pteridophyte plants. More primitive plants such as mosses and ferns.

These primitive plants depend on water for their growth and reproduction since they do not have true stems or roots. For this reason, they are attached to the ground using filaments called rhizoids in charge of absorbing water and mineral substances. They usually live in humid environments.

The spores are found in capsules called sporangium. When these are ripe the capsules are opened to disperse them and thus create new plants. located on a filament. When this capsule opens, the spores come out, and give rise to new plants.

Plants with reproduction by seeds

Gymnosperms and angiosperms, which are also known as higher plants.

Angiosperms are plants that do have a true root, stem, leaves, flowers, and fruit. These reproduce by seeds that are inside the fruit.

Gymnosperm plants also have true roots, stems, leaves, and flowers, but no fruit. Its flowers produce seeds, but these are not enclosed. They are usually found naked inside a cone or pineapple.

Classes of plants according to their duration

To finish, this is the classification of plants according to time that last:


They are those plants that live for several seasons since they have the resources to live more easily and for longer periods of time than the rest.

Biannual plants

These plants have a growth period that takes two full seasons. During the first, the plant reaches its maximum development so that, during the second, they give flowers and fruits with which the next generation is born.

Annual plants

Finally, there are annual plants that have a life span that only takes up one season. These plants are very fast growing and tend to germinate and bloom during the spring in general. They end their cycle between the period from autumn to winter.
