Answers
Answer:
Explanation:
Plants can be classified on the basis of their height, stem and branches. On these parameters, plants can be of three types, viz. herbs, shrubs and trees.
Herbs: Herbs are small plants which have soft stem. Examples: Wheat, paddy, cabbage, grass, coriander, etc.
Shrubs: These are bushy and medium- sized plants and they are somewhat bigger than herbs. Their branches start from just above the ground. Examples: Lemon, Coriander, Henna, Rose, etc.
Tree: These are tall and large plants with hard and woody stem. A single main-stem arises from the ground. The main-stem is called trunk. The trunk gives out many branches at certain height. The branches carry leaves, flowers and fruits. Examples: Mango, banyan, acacia, coconut, poplar, willow, etc.

A typical plant contains two main parts, viz. roots and stem. The stem bears leaves, flowers and fruits.
Root: The underground part of a plant is called root. It is usually pale in colour.
The root system consists of two types of root.
Tap root: This is composed of a main root which grows from the base of the stem. Many branches and sub-branches come out of the main root (tap root). Examples: pea, radish, carrot, mango, marigold, mustard etc.
Fibrous root: In this type, a cluster of thin fibre-like roots arise from the base of the stem. These roots spread out in the soil. Examples: Maize, grass, wheat, millet, etc.
Functions of Root
Roots hold the plant firmly in the soil and thus provide anchorage to the plant.
Roots absorb water and minerals from the soil.
Stem: Stem usually grows above the ground. The stem makes the main structural framework of the plant. The stem bears leaves, branches, buds, flowers and fruits. The point from where branches or leaves grow is called node. The portion of a stem between two consecutive nodes is called the internode.
