Respiration in Plants NEET Questions with Answers
Respiration in plants is the process by which they take in oxygen and release carbon dioxide to produce energy. This process occurs in every living cell of the plant, including roots, stems and leaves. The energy released during respiration is used for various functions like growth, repair and maintaining other life processes.
Unlike photosynthesis, which occurs only in the presence of light, respiration happens all the time, both day and night. Plants use glucose, which they produce during photosynthesis, as a fuel for respiration. The process primarily takes place in the mitochondria of the cells, where glucose is broken down into energy, water and carbon dioxide.

FAQs
- What is respiration in plants?
Answer: Respiration in plants is a metabolic process where they break down glucose to produce energy in the form of ATP. This process occurs in the mitochondria and involves both aerobic (with oxygen) and anaerobic (without oxygen) pathways. - How does respiration in plants differ from photosynthesis?
Answer: Respiration is a catabolic process that releases energy by breaking down glucose, while photosynthesis is an anabolic process that uses sunlight to synthesize glucose. Respiration occurs in all cells all the time, whereas photosynthesis occurs only in chlorophyll-containing cells during daylight. - What are the types of respiration in plants?
Answer: Plants undergo two types of respiration:
- Aerobic Respiration: Occurs in the presence of oxygen and involves the complete oxidation of glucose into carbon dioxide, water and energy (ATP).
- Anaerobic Respiration: Occurs in the absence of oxygen, leading to the partial breakdown of glucose into ethanol or lactic acid and a smaller amount of energy.
- Why is respiration in plants included in the NEET syllabus?
Answer: Respiration in plants is included because it is a fundamental biological process essential for energy production and life processes in plants. Understanding it helps students connect plant physiology with overall biological concepts. - How can I prepare for questions on respiration in plants for NEET?
Answer: To prepare, focus on understanding the mechanisms of respiration, the differences between aerobic and anaerobic respiration and the role of cellular organelles like mitochondria. Practice questions from past papers to solidify your understanding.
