Question

Which of the following statements is correct with respect to photosynthesis and respiration in plants?

• A. Respiration takes place both during day and night time.
• B. Respiration takes place when plant is not performing photosynthesis.
• C. During respiration plants take in carbon dioxide and release oxygen.
• D. Rate of photosynthesis is maximum during night time.

Answer 1

The correct option is A Respiration takes place both during day and night time.

$\bullet$ Plants perform respiration both during day and night time.
$\bullet$ During respiration plants take in oxygen and release carbon dioxide.
$\bullet$ Photosynthesis takes place in presence of light only.
$\bullet$ The rate of photosynthesis is maximum during the day as compared to respiration.
$\bullet$ The amount of oxygen released during photosynthesis is much more than the oxygen plants use in respiration.
