Question

At midday (12pm, Noon), what is happening in the leaf of a plant?
A) Cellular Respiration
B) Photosynthesis
C) Mainly photosynthesis and some cellular respiration
D) None of the above

Answer 1

Answer:

C

Explanation:

Noon is the peak amount of sun shining. Therefore the plant will be carrying out a lot of photosynthesis using the light. Cellular respiration happens regularly as well

Answer 2

At midday, what is happening in the leaf of a plant would be photosynthesis and cellular respiration. The correct option would, therefore, be C.

Photosynthesis has two reactions:

1. Light dependent reaction
2. Light independent reaction

The light dependent reaction is rate determining step of photosynthesis. Hence, photosynthesis proceeds at normal rate during the day.

Cellular respiration, on the other hand, takes place with or without light.

Hence, at 12 pm, Noon, both photosynthesis and cellular respiration will be taking place simultaneously in the leaf of plants.
