Question 13

Q13) State the utility of oxygen for respiration in

  1. Living organisms
  2. Plants

Solution:

  1. Respiration of living organisms involves inhaling oxygen to carbon & hydrogen present in food material which forms carbon dioxide , water vapor and energy in the form of heat.

Glucose + Oxygen → Carbon dioxide + water vapour + Energy

  1. Plant respiration is the process of plants using up the sugars made through photosynthesis and turning them into energy for growth, reproduction, and other life processes. Plant respiration involves taking in oxygen and releasing it as carbon dioxide into the atmosphere (air).

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
