Question

The process of carbon assimilation is known as –

• A. transpiration
• B. respiration
• C. photosynthesis
• D. excretion

Answer 1

The correct option is C

photosynthesis

The correct option is C.

Explanation of the correct option :

1. Carbon dioxide is taken from the atmosphere by plants during photosynthesis, and the carbon from the atmosphere is utilized to make glucose in the cells of the organism.
2. Carbon assimilation is the process of incorporating carbon from atmospheric carbon dioxide into cell components.
3. The photosynthetic carbon assimilation of plants is an important part of the global carbon cycle. The C3 pathway, often known as the Calvin cycle, is the process by which plants fix carbon primarily into 3-phosphoglycerate.

Explanation of the incorrect options:

Option A:

The evaporation of water from plants is known as transpiration. The water evaporates through the stomata on the leaves' surface.

Option B:

The process of taking in oxygen (inhalation) and giving out carbon dioxide (exhalation) is called respiration.

Option D:

The process of removing waste products produced in the cells of living organisms is called excretion.

Final answer: The process of carbon assimilation is known as photosynthesis
