4th Class Science Plants and Animals Respiration in Plants

   Respiration

Like all living organisms, plants also go through the process of respiration. This process is essential, as it provides energy and the carbon escalation for growth and maintenance. Plants consume about 25 - 75% of all the carbohydrates produced in photosynthesis.

 Sugar + Oxygen  Carbon dioxide + Water + energy.

Plants, like other living things use atmospheric oxygen to breakdown glucose (food produced in photosynthesis) into carbon dioxide and water for the release of energy. This energy is used for its growth and maintenance. In plants, all living cells of root, stem and leaf take in oxygen independently and give out carbon dioxide and water. Hence in plants, there is little transport of gases, from one part to another, occurs Respiration in plants occur at a much slower rate as compared to animals.
