The Plant Kingdom
 

We are incorporated in a society where the majority of the students study only for marks and left the important things. Meanwhile, we are unaware of the nature like plants, animals etc...that surrounds us eventhough we studied about in our early days. 

Let us rewind about the plant kingdom in a brief here.

Plant Kingdom:-

The plant kingdom is majorly classified in to cryptogams and phanerogams.

What is cryptogam?

The cryptogams are the non-flowering plants. They are majorly classified in to 

Thallophyta

Bryophyta

Pteridophyta

These are classified depending on the presence of roots, stems and leaf-like structures.

Thallophyta:- 

The plants in this category do not have a differentiated root, stem and leaves. The body is simple and it is called as “thallus”. 

Eg:- algae, bacteria, fungi and lichens.

Bryophyta:-

The plants in this category have defined stem and leaf like structures, but no roots. 

Eg:- Mosses

Pteridophyta:-

The plants in this category have a structured root, stem and leaves. But they don’t flower. 

Eg:- Ferns


What is Phanerogam? 

Phanerogams are the flowering plants which are divided in to 

Gymnosperms &

Angiosperms

These are divided based on the presence or absence of fruits.These are also called as Spermatophytes. The higher plants belong to this group. The reproduction through seeds is the outstanding feature of this group. 

Gymnosperms:- 

The Gymnosperms are called as the “Ever green plants”. The Gymnosperms have roots, stems, leaves, flowers and naked seeds . The flowers are unisexual and simple. These are arranged in cone like structures. The roots are well developed and it has needle shaped leaves.
