In plants, every part such as root, stem executes respiration as plants do not possess any particular organs like animals for the exchange of gases. The roots of a plant take oxygen required for respiration from the air present in between the soil particles by the process of diffusion. Question 3 How does exchange of gases occur in plants? Question 2 How does respiration take place in plants? In plants, there are two types of respiration: dark respiration and photo respiration. The oxidation of pyruvic acid into CO 2 and water takes place through this cycle. Photorespiration Photosynthesis is divided broadly into two main steps.

The direction of diffusion depend upon environmental conditions and requirement of plant. Based on this, we have two types respiration: Aerobic respiration : takes place oxygen; Anaerobic respiration : takes place without the presence of oxygen; Respiration In Plants. Each plant part takes care of its own gas- exchange needs. Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P. University) and has many years of experience in teaching. Class XI Chapter 14 – Respiration in Plants Biology Page 4 of 10 Question 4: What are the main steps in aerobic respiration? It is all worth it! Differentiate between (a) Respiration and Combustion (b) Glycolysis and Krebs’ cycle (c) Aerobic respiration and Fermentation Answer:- (a) Respiration takes place in cells of living beings, while combustion can take place anywhere. Students can download CBSE Class 11 Biology Chapter 14- Respiration in Plants Revision Notes in … In plants, respiration occurs at a much slower rate than in the animals. (ii) Oxygen is given out as waste material. i like the mindset of this website. (i) It takes place in all the animals and plants. How does respiration occur in roots? Last Updated on March 20, 2019 By Mrs Shilpi Nagpal 3 Comments. First, each plant part takes care of its own gas-exchange needs. For the process of respiration, plant takes O 2 and releases CO 2. … Thus, Like other organisms, plants also respire for their survival. Plants purify air by: (a) transpiration (b) photosynthesis (c) respiration (d) absorption of water Answer: (b) photosynthesis. When we perform a heavy exercise like running, cycling, walking, weight lifting, etc., we require a large amount of energy. The large inter-cellular spaces ensure that all the cells are in contact with air. Important Note: Respiration in plants is a process that spontaneously occurs the whole day, but photosynthesis only occurs during the day time, under the sunlight.The respiration rate of plants is higher during the night as the photosynthesis ceases. In this process of cellular respiration, plants generate glucose molecules through photosynthesis by capturing energy from sunlight and converting it into glucose. The respiration which takes place in the absence of oxygen is called anaerobic respiration. The end product of this respiration is water and carbon dioxide. Roots, stems and leaves respire at rates far lower than animals do. Remember that respiration is not the same as breathing, so take care - plants do not breathe. This process takes place in fungi, bacteria and several endoparasites. Carbon dioxide and oxygen are exchanged in and out of the cells by the process of; Diffusion is directed by environmental conditions and the requirements of the plants. Plants take part in respiration all through their life as the plant cell needs the energy to survive, however, plants breathe differently, through a process known as Cellular respiration. Where does it take place? Although plants require carbon dioxide to produce carbohydrates through photosynthesis, they also use oxygen to perform respiration. Biology Class-IX 4 Question Bank 3. Filed Under: Class 10, Life processes Tagged With: diffusion. Cellular respiration is a process that takes place inside the cells where energy is released by the breakdown of glucose molecules. Pro Lite, Vedantu The process of breakdown of food (glucose) in the presence of oxygen is known as aerobic respiration. Class 10th Science Biology Chapter 6 Life Processes by Mathsking.
