The Plants Kingdom

I write some information about The Plants Kingdom.

Scientists know about 360,000 species of the plant kingdom. Most of the plants differ from one another in size, shape and structure. For the sake of study, the plant kingdom has been divided into two sub-kingdoms- Thallophyta and embrophyta. In the thellophyta group, the plants do not develop from an embryo and their morphology is very simple. In the embryophyta subkingdom, plants develop from an embryo ad have complicated morphology. Every subkingdom is divided into phyla and every phyla into subphyla. Subphyla are further divided into subclasses.

Classification of plant kingdom

1.        Subkingdom- Thallophyta- The simple plants which do not form an embryo.

Phyla Algae


Cyanophyta- Blue green

Euglenophyta – Buglena etc.

Chlorophyta – Green algae

Chrysophyta – Yellow green and golden brown algae and diatom, etc.

Phaeophyta – Brown alage

Rodophyta – Red algae

Pyrophyta – Crypto-monads, Dinoflagillates, etc.

Phyla Bacteria Phyla Fungi


Schizomycophyta – Bacteria

Myxomycophyta – Slimmold.

Eumycophyta – Higher fungi.

2.       Subkingdom- embryophyta- embryo- bearing complex plants.


Bryophyte – Atractheata, moss and liverwort, etc. these lack vascular bundles

Trachoeophyta – Trac heata. These plants have vascular bundles like fern.



Psilopsida – Rootless and leafless compound plants. These have become completely extinct.

Lycopsida – Clubmoss and other related species. Their vascular system is simple and leaves are thick and green.

Sphyenopside – Horsetail and other related species. Their vascular system is simple, leaves are compound, thick and scale-like.

Pteropsida – Their vascular system is complex and leaves are large and clear.



Fillicineae – fern plants.

Gymnospermae – pine, fir, spruce, etc.

Angiospermae- flowering plants as    rose, magnolias, lilacs, apple, lilly, orchid, etc.
