FAQs on Respiration in Plants Video Lecture - Biology Class 11 - NEET

1. What is respiration in plants?
Ans.Respiration in plants is the process by which they convert glucose and oxygen into energy, carbon dioxide, and water. This process takes place in the mitochondria of plant cells and is essential for growth, reproduction, and overall metabolic activities.
2. How does respiration in plants differ from photosynthesis?
Ans.Respiration in plants is the opposite of photosynthesis. While photosynthesis occurs in the presence of sunlight and converts carbon dioxide and water into glucose and oxygen, respiration uses glucose and oxygen to release energy, producing carbon dioxide and water as byproducts.
3. What are the types of respiration in plants?
Ans.Plants primarily undergo two types of respiration: aerobic respiration, which requires oxygen and produces more energy, and anaerobic respiration, which occurs in the absence of oxygen and yields less energy, often resulting in the production of byproducts like ethanol or lactic acid.
4. When does respiration occur in plants?
Ans.Respiration in plants occurs continuously, both day and night. However, during the day, photosynthesis also takes place, leading to a balance where the oxygen produced can be used for respiration. At night, plants solely rely on respiration for energy.
5. How do environmental factors affect plant respiration?
Ans.Environmental factors such as temperature, oxygen availability, and moisture levels can significantly affect plant respiration. Higher temperatures can increase the rate of respiration, while low oxygen levels can shift plants toward anaerobic respiration, affecting their growth and health.
