Introduction
Life is impossible without plants. We do find a variety of plants around us. These plants we come across practically everywhere. Plants differ in size and shape. Some are small while others are big. 

Type of Plants
On the basis of their size and shape, plants have been divided into the following three categories.
(i) Herbs         (ii) Shrubs         (iii) Trees
Herbs : Plants which have soft, green and perishable stems are called herbs. They are generally smaller in size, they are not more than one metre in height and may live for 1-2 seasons. Examples of some herbs are grass, maize, rice, mint, coriander, etc. 
Shrubs : Plants with woody stems, with branches of almost equal size arising from the stem immediately above the soil are called shrubs. They look like bushes and are medium-sized plants. They survive for many years, though less than trees. Example : China rose, lemon, pomegranate, jasmine, nerium, etc.
Tree : The trees are tall and big plants. They have one hard woody stem called trunk.It bears woody branches, twigs and leaves at some distance above the ground. Coconut and palm are also trees, though they do not contain branches. Trees generally survive for many years. Examples : Mango, neem, palm, banyan, etc.

 

Creepers : Plants with weak stems that can not stand upright and spread on the ground are called creepers eg. Bottle gourd, bitter gourd, pumpkin.

Climbers : Plants which take support on neighbouring structure and climb up are called climbers eg. Betel, grapes, Money plants.
