FAQs on Index: Respiration in Plants - Biology Class 11 - NEET

1. What is respiration in plants?
Ans. Respiration in plants is the process by which plants take in oxygen and release carbon dioxide. It involves the breakdown of glucose molecules to produce energy, which is essential for various metabolic processes in plants.
2. How does respiration occur in plants?
Ans. Respiration in plants occurs through small openings called stomata present on the surface of leaves. Oxygen enters the plant through these stomata and is used in the mitochondria of plant cells to break down glucose and release energy. Carbon dioxide, a byproduct of respiration, is then released back into the atmosphere through the stomata.
3. What is the importance of respiration in plants?
Ans. Respiration is vital for plants as it provides the energy needed for various physiological processes, such as growth, reproduction, and nutrient absorption. It also allows plants to convert stored carbohydrates into usable energy, especially during periods of limited sunlight or photosynthesis.
4. How does respiration differ from photosynthesis in plants?
Ans. Respiration and photosynthesis are two distinct processes in plants. While photosynthesis involves the conversion of sunlight, water, and carbon dioxide into glucose and oxygen, respiration is the process of breaking down glucose to release energy. Photosynthesis occurs in the presence of light, whereas respiration occurs both in the presence and absence of light.
5. Can plants respire without sunlight?
Ans. Yes, plants can respire without sunlight. While photosynthesis requires sunlight for the production of glucose, respiration can occur in plants even during the night or in areas with limited light. During these periods, plants rely on stored carbohydrates, such as starch, for energy production through respiration.
