A. Shrubs
B. Herbs
C. Trees
D. Long trees

Answer 1

Based on growth the plants are broadly categorized into three groups: herbs, shrubs, and trees. Plants are very essential to human beings as well as ecosystems. It is a major source of oxygen and captures a huge amount of carbon dioxide.

Complete answer: A shrub or bush is a small- to medium-sized woody plant and Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be of two types- deciduous or evergreen. They are distinguished from trees on the basis of a variety of factors such as their multiple stems and shorter height. They are less than 6 m-10 m tall. Small shrubs less than 2 m (6.6 ft) tall are sometimes also known as subshrubs. They are flexible and are not easily breakable or fragile. Some common shrubs include rose, lemon, and henna. Shrubs are usually very short and have a height of less than 13 feet. The stems are no more than about three inches in diameter.
-Herbs are short plants that consist of green and very delicate stems. Compared to other plants herbs have very few branches and can come off easily if plucked from the soil. Grass, mint, and wheat are some examples of herbs. Herbaceous plants have slender, tender, and green stems. Herbaceous plants have stems made up of cellulose and are not as rigid as lignin. Hence, they decompose relatively easily. whereas the woody plants possess stems made up of lignin that is a solid and rigid structure. It prevents the stems from damage by insects.
-Trees are big and tall plants. They have very thick, woody and hard stems called the trunk. This single main stem also known as the trunk gives rise to the branches that bear leaves, flowers, and fruits. Some trees can be branchless as well like coconut trees; i.e., they have only one main stem and that single main stem bears leaves, flowers, and fruits all by itself. The life-span of the trees is very large. i.e., for several years. Banyan, mango, neem, cashew, teak, oak are some examples of trees.
Hence, the correct answer is Option A.

Note: A shrubbery is a garden filled with shrubs as the main feature. The word bush can also refer to a type of plant community like the Australian bush. It is often characterized by scrubby, open woodland and is a generic term for the Eucalyptus dominated woodland.
