FAQs on Nutrition in Amoeba - Nutrition in Animals Video Lecture - Class 7
| 1. What is the nutrition process in Amoeba? |  |
Ans. Amoeba obtains its nutrition through a process called phagocytosis. It engulfs food particles by extending its pseudopodia around them, forming a food vacuole. Digestive enzymes are then released into the vacuole, breaking down the food for absorption by the amoeba's cell membrane.
| 2. What kind of food does Amoeba consume? | |
Ans. Amoeba is a heterotrophic organism, which means it consumes other organisms for food. It feeds on microorganisms such as bacteria, algae, and other small protists. Amoeba can also consume organic debris present in its environment.
| 3. How does Amoeba digest its food? | |
Ans. Amoeba digests its food through intracellular digestion. Once the food vacuole is formed, digestive enzymes are secreted into the vacuole. These enzymes break down the food into simpler substances. The digested nutrients are then absorbed through the cell membrane of the amoeba, while undigested waste is eliminated.
| 4. Can Amoeba perform photosynthesis to obtain nutrition? | |
Ans. No, Amoeba is unable to perform photosynthesis as it lacks chloroplasts. Unlike autotrophic organisms, Amoeba cannot produce its own food using sunlight, water, and carbon dioxide. It relies solely on consuming other organisms for its nutrition.
| 5. How does Amoeba obtain energy from its food? | |
Ans. Amoeba obtains energy from its food through the process of cellular respiration. After digestion, the nutrients are absorbed into the cytoplasm of the amoeba's cell. These nutrients are then further broken down through a series of chemical reactions, releasing energy in the form of ATP (adenosine triphosphate) for the amoeba's metabolic activities.
