Question

Respiration is the phenomenon opposite to photosynthesis. Explain.

Answer 1

Respiration:

• Respiration in plants is defined as a process in which plants break down glucose in the presence of oxygen to liberate energy used for the growth and development of the plant.

Photosynthesis:

• Photosynthesis is the process in which plants synthesize glucose and release oxygen by utilizing water and carbon dioxide in the presence of sunlight.

The main points of difference between photosynthesis and respiration include:

Photosynthesis	Respiration
Photosynthesis uses atmospheric carbon dioxide and water to synthesize sugars	Respiration uses atmospheric oxygen to break down sugars to release energy.
The process of photosynthesis occurs during the daytime when sunlight is present	Respiration in plants occurs during the night.

Thus, photosynthesis and respiration function exactly opposite to each other.
