FAQs on Respiration In Plants in One Shot (NCERT) Video Lecture - Biology Class 11 - NEET

1. What is respiration in plants?
Ans. Respiration in plants refers to the process of converting stored energy in the form of glucose into usable energy in the form of ATP (adenosine triphosphate). It involves the exchange of gases, with oxygen being taken in and carbon dioxide being released.
2. How do plants perform respiration?
Ans. Plants perform respiration through various cellular processes. The primary pathway is aerobic respiration, which occurs in the presence of oxygen. During aerobic respiration, plants break down glucose molecules and release energy. This process takes place in the mitochondria of plant cells.
3. What is the importance of respiration in plants?
Ans. Respiration is crucial for the survival of plants as it provides them with the necessary energy to carry out various metabolic processes. It enables plants to grow, reproduce, and respond to their environment. Additionally, respiration helps in the breakdown of stored nutrients for energy release.
4. How does respiration in plants differ from respiration in animals?
Ans. Respiration in plants and animals share some similarities, such as the exchange of gases and the production of ATP. However, there are a few key differences. Plants primarily respire through their leaves and roots, while animals mainly respire through their lungs. Plants also undergo photosynthesis, which is not a process in animal respiration.
5. How does temperature affect respiration in plants?
Ans. Temperature plays a vital role in plant respiration. Generally, respiration rates increase with higher temperatures, as enzymes involved in respiration function more efficiently. However, extremely high temperatures can lead to denaturation of enzymes, adversely affecting respiration. Similarly, very low temperatures can slow down respiration processes in plants.
