Question

In the desert areas plants have thorns instead of _____.
A. Stem
B. Bark
C. Bud
D. Leaf

Answer 1

Hint: Desert is an area of arid land, which has very little precipitation which makes it difficult for the survival of animals, plants, and human beings. The temperatures in the desert areas are extreme ranging from 50-60 degrees celsius.

Complete answer: - Option A: Stem is a part of the plant that transports water and dissolved substances from the roots to the other parts of the plants. It also holds and stores water and nutrients. It supports leaves, fruits, and flowers. It is present in all plants. Hence, this is an incorrect option.
- Option B: Bark is the outermost part of the plants which are woody in nature. It surrounds the stems and roots of these plants. It protects the plants and trees from the outside environment. Hence, this is an incorrect option.
- Option C: Bud occurs in the tip of a stem or the axil of a leaf and is an underdeveloped flower or fruit. Hence, this is an incorrect option.
- Option D: Leaf is a part of the plant that is extended on the stems and is green in color due to the presence of Chlorophyll in it. It contains stomata which are responsible for photosynthesis which produces energy for the activities. In deserts as the amount of rainfall is less so the plants develop thorns instead of leaves as there are no pores in thorns and are hard in nature which makes it possible for the survival of plants in the deserts. Hence, this is the correct option.

Therefore, The correct answer is Option D.

Note: The plants that are found in desert areas have the tendency to go without fresh water for years. The plants adapt to this climate by growing long roots so that they can get underground water. The plants have special means for storing and conserving water. Different plants found are cactus and poppies.
