Question

The amount of carbon dioxide fixed by 1 gm of chlorophyll within 1 hour is known as

• A. Photosynthetic number
• B. Respiratory quotient
• C. Photolysis
• D. None of the above

Answer 1

The correct option is A Photosynthetic number

Photosynthesis is the process where carbon dioxide is taken in and oxygen is released from water. The carbon dioxide is fixed by the photosynthetic pigments like chlorophyll and utilised for the production of glucose. The amount of carbon dioxide fixed by 1 gm of chlorophyll within 1 hour is known as the photosynthetic number. The efficiency of the plant in production of food is quantified by the photosynthetic number.

Thus, the correct answer is option 'Photosynthetic number'.
