The breaking of C-C bonds of complex coumpounds through 
oxidation within the cells, leading to release of considerable 
amount of energy is called respiration . The compounds that 
are oxidised during this process are known as respiratory 
substrate.

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

1. What is respiration in plants?
Ans. Respiration in plants is a vital metabolic process that involves the conversion of glucose into energy, carbon dioxide, and water. It occurs in all living plant cells and helps in the production of ATP (adenosine triphosphate), the energy currency of cells.
2. How do plants obtain oxygen for respiration?
Ans. Plants obtain oxygen for respiration through tiny pores called stomata present on the surface of leaves and stems. These stomata open during the day and allow the entry of oxygen from the atmosphere into the plant cells. Oxygen is then utilized in the process of cellular respiration.
3. What are the different types of respiration in plants?
Ans. There are two types of respiration in plants: aerobic respiration and anaerobic respiration. Aerobic respiration occurs in the presence of oxygen and is the most common type of respiration in plants. Anaerobic respiration, on the other hand, occurs in the absence of oxygen and is less common.
4. How does respiration in plants differ from respiration in animals?
Ans. Respiration in plants and animals share some similarities, but there are also significant differences. Plants perform respiration through various tissues, including leaves, stems, and roots, while animals mainly rely on specialized respiratory organs like lungs. Additionally, plants release oxygen as a byproduct of respiration, whereas animals release carbon dioxide.
5. What factors can affect the rate of respiration in plants?
Ans. Several factors can affect the rate of respiration in plants. Temperature plays a crucial role, as respiration rates tend to increase with higher temperatures. Oxygen availability, the presence of enzymes, and the concentration of glucose also impact respiration rates. Additionally, certain external factors like light intensity and humidity can influence the overall rate of respiration in plants.
