   A. An opaque object does not allow light to pass through it. For example, wood.

7. Getting to Know Plants

1. Q. What is photosynthesis? Give an example.
   A. Photosynthesis is the process by which plants make food using sunlight. For example, green leaves prepare food in sunlight.

2. Q. What is germination? Give an example.
   A. Germination is the sprouting of a seed. For example, a bean seed growing into a plant.

3. Q. Which part absorbs water? Give an example.
   A. The root absorbs water from the soil. For example, roots of a mango plant absorb water.

8. Body Movements

1. Q. What is a joint? Give an example.
   A. A joint is the place where two bones meet. For example, the knee joint.

2. Q. What is the skeleton? Give an example.
   A. The skeleton is the framework of bones in our body. For example, the skull is part of the skeleton.

3. Q. What helps in body movement? Give an example.
   A. Muscles help in body movement. For example, leg muscles help us to run.

9. Living Organisms and Their Surroundings

1. Q. What is respiration? Give an example.
   A. Respiration is the process of breathing. For example, humans breathe in oxygen.

2. Q. What is excretion? Give an example.
   A. Excretion is the removal of waste from the body. For example, sweating removes waste.
