FAQs on Worksheet: Photosysthesis and Respiration - Biology Class 7 ICSE
| 1. What is photosynthesis and why is it important for plants? |  |
Ans.Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. It occurs mainly in the chloroplasts of plant cells. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is crucial for plants as it provides them with the energy they need to grow and thrive. Additionally, photosynthesis is essential for life on Earth, as it produces oxygen, which is vital for the survival of most living organisms.
| 2. How do respiration and photosynthesis differ from each other? | |
Ans.Respiration and photosynthesis are two fundamental biological processes. Photosynthesis occurs in plants, where sunlight is used to convert carbon dioxide and water into glucose and oxygen. In contrast, respiration is a process that occurs in all living organisms, including plants and animals, where glucose is broken down with the help of oxygen to release energy, carbon dioxide, and water. Essentially, photosynthesis stores energy, while respiration releases it.
| 3. What role do chlorophyll and sunlight play in photosynthesis? | |
Ans.Chlorophyll is the green pigment found in the chloroplasts of plant cells. It plays a critical role in photosynthesis by absorbing sunlight, particularly in the blue and red wavelengths. This absorbed light energy is then used to convert carbon dioxide and water into glucose. Without chlorophyll and sunlight, photosynthesis would not occur, and plants would not be able to produce the energy they need for growth.
| 4. What are the byproducts of respiration in living organisms? | |
Ans.The byproducts of respiration in living organisms are carbon dioxide (CO₂) and water (H₂O). During cellular respiration, glucose is broken down in the presence of oxygen to release energy. This process can be summarized as glucose + oxygen → carbon dioxide + water + energy. The carbon dioxide produced is then expelled from the body, while water may be used in various cellular processes or excreted.
| 5. Why is respiration considered a vital process for animals? | |
Ans.Respiration is considered vital for animals because it provides the necessary energy required for all bodily functions, including movement, growth, reproduction, and maintaining homeostasis. The energy released during respiration is stored in the form of adenosine triphosphate (ATP), which is used by cells to perform work. Without respiration, animals would not be able to sustain life, as they would lack the energy to carry out essential processes.
