2.D. Give reasons for the following.1. Plants do not have breathing organs.2. Energy released during anaerobic respirationis much less than energy released duringaerobic respiration.3. Plants do not take in oxygen and give outcarbon dioxide during daytime. Does it meanplants do not respire during day?4. To demonstrate that carbon dioxide isproduced during respiration by plants also,we use sprouted seeds and not green plants. |

Answer» Answer 1. The reason is that plants require carbon DIOXIDE to get the ENERGY out of food, which can be done by the stomata in the leaves. Thus, they don't have breathing organs. Answer 2. This is because the glucose is not completely broken down thus, reducing the energy released. Answer 3. Plants respire throughout the DAY, while photosynthesis takes place only in the presence of sunlight. In daytime, CO2produced during respiration is used by the plants in photosynthesis. So, CO2 is not released into the environment. Answer 4. Since, the sprouts are germinating they produce more carbon dioxide then green plants(which also provide oxygen due to photosynthesis) |
