Question

Which of the following statements is true ?

A.

Excretion takes place only in animals

B.

The amount of oxygen released by plants during photosynthesis is same as that of taken in during respiration

C.

Plants reproduce through vegetative propagation only

D.

Plants remove water as vapour and carbon dioxide

Correct option is D

The correct answer is Plants remove water as vapour and carbon dioxide.
Excretion takes place only in animals: This statement is false Excretion is a biological process that occurs in both animals and plants. Animals excrete waste products such as urine, while plants excrete waste products through various mechanisms, including the elimination of excess water through transpiration and the shedding of leaves.
The amount of oxygen released by plants during photosynthesis is the same as that taken in during respiration: This statement is false. During photosynthesis, plants take in carbon dioxide and release oxygen. However, during respiration, plants take in oxygen and release carbon dioxide. The processes of photosynthesis and respiration in plants involve different gas exchange reactions and are not in balance with each other.
Plants reproduce through vegetative propagation only: This statement is false. While vegetative propagation is one method of plant reproduction, plants can also reproduce through other means, suh as seed production, spore formation, and budding Vegetative propagation involves the production of new plants from vegetative structures like stems, roots, or leaves, but it is not the only method of plant reproduction.
Plants remove water as vapor and carbon dioxide: This statement is true. Plants have specialized structures called stomata, primarily present on their leaves, through which they exchange gases with the environment. During photosynthesis, plants absorb carbon dioxide from the atmosphere and release oxygen as a byproduct. In the process, water vapor is also lost through transpiration, which is the evaporation of water from the stomata.
