Important Questions with Answers

Practice the following questions regularly to strengthen your understanding of the chapter.

One Mark Questions

Question 1. What is a living organism?

Answer: A living organism is a living thing that performs life processes such as growth, respiration, reproduction, and response to stimuli.

Question 2. Name any two characteristics of living things.

Answer: Growth and respiration.

Question 3. What is germination?

Answer: Germination is the process by which a seed develops into a young plant under suitable conditions.

Question 4. Name two essential conditions required for seed germination.

Answer: Water and air.

Question 5. Is sunlight essential for the germination of most seeds?

Answer: No. Most seeds do not require sunlight for germination, but sunlight is needed for the growth of seedlings.

Question 6. What is a stimulus?

Answer: A stimulus is any change in the surroundings that causes a living organism to respond.

Question 7. What is respiration?

Answer: Respiration is the process by which living organisms release energy from food.

Question 8. Name the first stage in the life cycle of a mosquito.

Answer: Egg.

Question 9. What is the young stage of a frog called?

Answer: Tadpole.

Question 10. Why do living organisms reproduce?

Answer: They reproduce to continue their own species.

Two Mark Questions

Question 1. Differentiate between living and non-living things.

Answer:

Question 2. Why do seeds need water during germination?

Answer: Water softens the seed coat and activates the embryo, allowing it to begin growth and develop into a seedling.

Question 3. Why is air necessary for seed germination?

Answer: Seeds require oxygen from the air for respiration, which provides energy needed for germination.

Question 4. Why is a wooden log considered non-living?

Answer: A wooden log does not perform life processes such as growth, respiration, or reproduction, so it is considered non-living.

Question 5. Write two similarities between the life cycles of plants and animals.

Answer:

• Both begin life from a new stage such as a seed or an egg.
• Both grow, reproduce, and finally die.

Three Mark Questions

Question 1. Explain the conditions required for seed germination.

Answer:

• Seeds require sufficient water.
• Seeds need air for respiration.
• Suitable temperature is necessary.
• Most seeds do not require sunlight for germination, but seedlings need sunlight for further growth.

Question 2. Explain how plants respond to light.

Answer:

Plant shoots grow towards the source of light, while roots usually grow downward into the soil. This response helps the plant receive maximum sunlight for photosynthesis and absorb water and minerals through the roots.

Question 3. Describe the life cycle of a mosquito.

Answer:

A mosquito passes through four stages: egg, larva, pupa, and adult. Each stage has a different body structure. The adult female mosquito lays eggs near water, and the cycle repeats.

Question 4. Describe the life cycle of a frog.

Answer:

A frog's life cycle begins with eggs. The eggs hatch into tadpoles, which gradually develop legs and lungs. They become froglets and finally develop into adult frogs that live both on land and in water.

Question 5. Explain why growth alone cannot be used to identify living things.

Answer:

Some non-living things, such as crystals, may appear to increase in size under certain conditions. Therefore, an object is considered living only if it performs all essential life processes such as respiration, reproduction, excretion, and response to stimuli along with growth.

Long Answer Questions

Question 1. Describe the characteristics of living organisms.

Answer:

Living organisms show several common characteristics. They obtain food for energy, grow and develop, respire, remove waste materials, respond to changes in the environment, reproduce, and eventually die. These characteristics help us distinguish living organisms from non-living things.

Question 2. Explain the process of seed germination and the conditions required for it.

Answer:

Seed germination begins when a seed receives sufficient water, air, and a suitable temperature. Water softens the seed coat and activates the embryo. The embryo starts growing, the root emerges first, followed by the shoot. Most seeds do not require sunlight for germination, but sunlight is essential for the healthy growth of the young plant.

Question 3. Compare the life cycles of a plant, a mosquito, and a frog.

Answer:

All three life cycles involve growth, development, reproduction, and continuation of the species, but the stages differ according to the organism.

Question 4. Explain the importance of studying life cycles.

Answer:

Studying life cycles helps us understand how living organisms grow, reproduce, and survive. It also helps farmers improve crop production, supports scientists in controlling harmful insects such as mosquitoes, and enables us to protect biodiversity and maintain ecological balance.

Question 5. Explain how the characteristics of living organisms help us distinguish them from non-living things.

Answer:

Living organisms perform essential life processes such as nutrition, respiration, growth, movement, excretion, reproduction, and response to stimuli. Non-living things do not perform these activities. Although some non-living objects may move with external force, they cannot grow, reproduce, or respond like living organisms. Therefore, the presence of all life processes helps us identify living organisms correctly.
