Part A: Review and Revision

20 FAQs with Answers Based on the Topics Taught During the Term

1. What is reproduction in plants?
   • Reproduction in plants is the process through which plants produce offspring. This can happen through seeds, flowers, or spores.
2. How do plants reproduce sexually?
   • Plants reproduce sexually through the process of pollination, where pollen from the male part of one flower fertilizes the female part of another flower.
3. What is pollination?
   • Pollination is the transfer of pollen from one flower to another, enabling fertilization to occur.
4. What are the two main types of reproduction in plants?
   • The two main types of reproduction in plants are sexual reproduction (involving seeds) and asexual reproduction (like cuttings and runners).
5. What are domestic animals?
   • Domestic animals are animals that live with humans and are kept for various purposes such as food, companionship, or work.
6. How do we group domestic animals?
   • Domestic animals can be grouped based on their diet: herbivores (eat plants), carnivores (eat meat), and omnivores (eat both plants and animals).
7. What do herbivores eat?
   • Herbivores eat only plants and plant-based foods like grass, leaves, and fruits.
8. What do carnivores eat?
   • Carnivores eat only other animals, such as meat.
9. What do omnivores eat?
   • Omnivores eat both plants and animals.
10. What is heat?
    • Heat is a form of energy that can transfer from one object to another. It makes things warmer.
11. How does heat transfer?
    • Heat can transfer through conduction (direct contact), convection (in liquids and gases), and radiation (through space).
12. What is the difference between heat and temperature?
    • Heat is the energy transferred between objects, while temperature measures how hot or cold an object is.
13. What is a conductor?
    • A conductor is a material that allows heat or electricity to pass through it easily, like metals.
14. What is an insulator?
    • An insulator is a material that does not allow heat or electricity to pass through it easily, like wood or rubber.
15. What is matter?
    • Matter is anything that has mass and occupies space. It exists in three states: solid, liquid, and gas.
16. What happens when matter changes state?
    • Matter can change from one state to another (solid to liquid, liquid to gas) by adding or removing heat.
17. What is maintenance?
    • Maintenance refers to the actions taken to keep equipment, machines, or systems in good working order through regular checks and repairs.
18. Why is maintenance important?
    • Maintenance is important because it ensures that equipment works well, lasts longer, and stays safe to use.
19. What is the difference between preventive and corrective maintenance?
    • Preventive maintenance is done to avoid problems before they happen, while corrective maintenance is done to fix problems after they occur.
20. How does maintenance benefit us?
    • Maintenance helps prevent breakdowns, improves safety, and ensures that equipment works efficiently.
