Kingdom of plants

There is a variety of plants around you. You can see that they have different leaves, stems, and fruits; why does this happen? Wouldn’t it be boring if all the plants were the same? Who can only eat apples all his life! Never! Therefore, we will talk here about the kingdom of plants. The plant kingdom includes green, brown and red algae, liver ferns, algae such as fonaria, ferns and seed plants with or without flowers, and have the following characteristics:

-Multicellular objects with walls with real central cells and many gaps.

-It contains photosynthesis pigment in green plastids, and the primary feeding method is photosynthesis.

-They are mainly immobile and live on a fixed substrate.

-Reproduction is non-sexual (primitive) or sexual. The multicellular genital organs, they form a multicellular embryo as it develops from the fertilized egg, while algae do not have the embryonic stage.

-The life cycle consists of the rotation of the two generations, the placental (monochromatic) and the bogey (dichromosome); this phenomenon is called generation rotation.


They are simple non-vascular plants that feed themselves, have monochrome sexual organs, and there is no formation of embryos, and they grow in special environments, such as:

-Cryophytes: These grow on ice.

-Thermophiles: These grow in hot water.

-Epiphytes: an intrusive aerobic plants, which are algae that grow on other plants (algae, seed pots). -For example, Oedogonium, Cladophora, and Vaucheria.

-Endophytes: Some blue-green algae grow as houseplants in other plants; for example, Anabaena grows in the Azolla fern plant.

– Parasites: Cephaleuros virescens moss grows as a parasite on tea leaves.


This is a group of the simplest primitive plants, which we also consider (amphibians in the botanical kingdom), and are more frequent in humid and shaded areas, some of which also grow in areas as diverse as very dry or aquatic areas, and reproduce sexually.

The antheridium is the sexual organ of males, while the arconium is the female sexual organ.


It refers to all these feathery plants such as fronds of ferns and has no flowers or seeds. These plants are mostly terrestrial; they also prefer shaded habitat and have a bogey.

Vascular vases usually contain a single distinct cell with three cut faces at the top.

Now, take a look at the categories in this group:

–     Psilopsida

These are the oldest known vascular plants, mainly (except Psilotum and Tmesipteris) from fossils.

The body of the plant is relatively less distinguished, and its roots are absent. Instead, you can find a double-branched (rhizome) (short lateral leg- rhizome).

–     Lycopsida

The vegetation is divided into roots, legs, and leaves. The leaves are generally small i. e. microphyllous with (unbranched conveyor ships. The spore cysts develop in the axis (the point of contact between the leg of the paper and the branch).

–     Sphenopsida

The trunk is divided into necklaces. Leaves are a leaf in a way that is insignificant for the contract.

–     Pteropsida

The vegetation is well characterized by the root, leg, and leaves, and the huge leaves resemble installed feathers.


Seed pots ( Angiosperms), or flowering plants, are the most common vascular plants in the world today. These plants are mainly responsible for changing the blues of the earth’s yellow and green vegetation, through their bright colors and strong odors. The term « seed pot » means « closed seeds, » because the eggs or potential seeds are surrounded by a hollow ovary.

We can divide the plants into two main groups in the seed pot (Dicotyledons & Monocotyledons )
All this was a small profile of the kingdom of plants , and there are so many species of them countless.
