FAQs
1. What are life processes? The basic functions performed by living beings to maintain life, such as nutrition, respiration, transportation, and excretion.
2. What is the difference between autotrophic and heterotrophic nutrition? Autotrophic nutrition involves making food (like photosynthesis), while heterotrophic nutrition involves consuming food prepared by others.
3. What is double circulation in humans? It is the passage of blood twice through the heart in one complete cycle – pulmonary and systemic circulation.
4. What is the functional unit of the kidney? The nephron is the structural and functional unit of the kidney.
5. How do plants excrete? Plants excrete by releasing oxygen, carbon dioxide, water vapor, gums, and resins.
