Question

How many kinds of plants are there?

Answer 1

Hint: Plants can be classified in several ways such as; according to their habitat like marine, freshwater, desert, tropical, temperate, according to whether they are seed-bearing and flowering or not like gymnosperms, and angiosperms or whether they are Monocots or Dicots, and according to their growth habits.

Complete answer:
Growth habits refer to the plant's growth, development, or change in the plant’s height, shape, and kind of growth it undergoes. Genetic factors as well as environmental factors play a key role in the growth habit.
Based on the growth habits, plants (that don’t need support) are classified into three groups: Herbs, Shrubs, and Trees.
-Herbs: These plants are short-sized with soft, green, and delicate stems without woody tissues. They are generally branchless, lack woody structures, and are high in nutritive benefits including vitamins and minerals. These plants complete their life cycle within one or two seasons. Examples of herbs are tomato, wheat, bananas, etc.
-Shrubs: These plants are medium-sized, woody plants taller than the herbs but shorter than a tree. The height of the shrubs usually ranges between six to ten meters tall. Their features involve bushy, hard, and woody stems with several branches. The life span of these plants usually depends upon the species. Examples of shrubs are rose, lemon, tulsi, henna, etc.
-Trees: Trees are tall and big plants and have very thick, woody, and hard stems known as the trunk. This trunk gives rise to many branches bearing leaves, flowers, and fruits and the weight of large arboreal animals such as leopards, gorillas. Trees like coconut are branchless trees and they have only one main stem that bears leaves, flowers, and fruits. The life span of trees is very large i.e. for several years. Examples of trees involve mango, neem, banyan, silver oak, teak, etc.

Note: Those plants that need supports are climbers and creepers. Climbers such as money plants and grapes have thin, weak stems with special adaptations that allow them to be used for support and upward growth. While creepers such as pumpkin or watermelon they cannot grow upwards even with support and are found along the ground.
