1. | No | No | Rock | Non-living; doesn't grow or respire |
2. | No | Yes | Burning Fire | Non-living; it utilizes oxygen but does not grow. |
3. | Yes | No | Virus | A virus can grow (reproduce) within a host cell but does not respire on its own. |
4. | Yes | Yes | Human/Animal | Living, growing, and respiring |
Question 3. You have learnt that different conditions are required for seed germination. How can we use this knowledge for the proper storage of grains and pulses?
Answer:
Grains and pulses can be stored properly by ensuring they are kept in a cool, dry place with low humidity and limited air exposure. This prevents germination by depriving the seeds of the necessary moisture, oxygen, and temperature needed to sprout.
Question 4. You have learnt that a tail is present in a tadpole, but it disappears as it grows into a frog. What is the advantage of having a tail in the tadpole stage?
Answer:
The tail in the tadpole stage is advantageous because it aids in swimming and movement in the aquatic environment. It allows the tadpole to propel itself through the water, find food, and evade predators.
Question 5. Charan says that a wooden log is non-living as it cannot move. Charu counters it by saying that it is living because it is made of wood obtained from trees. Give your arguments in favour or against the two statements given by Charan and Charu.
Answer:
Charan's statement: It is correct to say that a wooden log is non-living because it does not exhibit the key characteristics of living organisms, such as growth, reproduction, respiration, or response to stimuli.
Charu's statement: Although wood comes from a living tree, the log itself is no longer living. The cells in the wood are dead, and the log cannot perform any life processes.
Question 6. What are the similarities and distinguishing features in the life cycles of a mosquito and a frog?
Answer:
The table below shows the similarities and differences in the life cycles of a mosquito and a frog:
Feature | Mosquito | Frog |
Similarities |
|
|
Metamorphosis | Undergoes metamorphosis | Undergoes metamorphosis |
Water Dependency | Requires water for the larval stage | Requires water for early development (tadpole stage) |
Reproduction | Lays eggs | Lays eggs |
Distinguishing Features |
|
|
Life Stages | Egg, larva, pupa, adult | Egg, tadpole, adult |
Larval Stage | Aquatic larvae (wrigglers) feed on organic matter | Tadpoles are aquatic and have a more complex diet |
Adult Form | Insect with wings | Amphibian with legs |
Question 7. A plant is provided with all the conditions suitable for its growth. Draw what you expect to see in the shoot and the root of the plant after one week. Write down the reasons.
![shoot and root]()
Answer:
After one week, the shoot would have grown taller, with new leaves emerging. The existing leaves would have increased in size and turned a deeper green. The root system would have expanded, with new roots growing deeper and wider into the soil.
Reasons: The plant has favourable conditions (light, water, nutrients) for photosynthesis and growth. The shoot grows to capture more sunlight, and the roots grow to absorb more water and nutrients from the soil.

Question 8. Tara and Vijay set up the experiment shown in the picture. What do you think they want to find out? How will they know if they are correct?
![plant growth]()
Answer:
Tara and Vijay likely want to find out how light affects the direction of plant growth. They will know if they are correct if the plant stem bends towards the hole, demonstrating that plants grow towards a light source.
Question 9. Design an experiment to check if temperature has an effect on seed germination.
Answer:
Materials: Bean seeds, pots, soil, thermometer, refrigerator, and a warm location.
Procedure:
Divide the seeds into three groups.
Plant each group of seeds in separate pots with similar soil.
Place one pot in a refrigerator (low temperature), one at room temperature, and one in a warm location.
Water all pots equally and regularly.
Monitor and record the number of seeds that germinate in each pot over a set period (e.g., 10 days).
Observation: Count the number of seeds that germinate in each pot.
Conclusion: Compare the germination rates in the different temperature conditions. The temperature at which most seeds germinate is the optimal temperature for seed germination.

Important Questions from Class 6 Science Chapter 10
The questions are designed to test the understanding of how living things behave and survive. For more questions, students can use the NCERT Solutions for Class 6 Science Chapter 10 Living Creatures: Exploring Their Characteristics. This helps them to understand the exam pattern and difficulty level.
Question 1. Which of the following are the main characteristics of living things?
A. They can grow, move, reproduce, respond to stimuli, need food, and excrete waste
B. They are made only of metal and plastic
C. They do not need food or water
D. They cannot respond to their environment
Answer: The correct answer is option (A).
Explanation:
Living things are defined by several key characteristics that make them different from non-living things. These include the ability to grow, move, reproduce, respond to stimuli, require nutrition, and excrete waste. These features ensure the survival, adaptation, and continuation of life.
Question 2: What happens to air during inhalation and exhalation?
A. Air moves from inside to outside during inhalation and from outside to inside during exhalation
B. Air moves from outside to inside during inhalation and from inside to outside during exhalation
C. Air stays in the lungs during both inhalation and exhalation
D. Air moves randomly in and out of the body
Answer: The correct answer is option (B).
Explanation: Inhalation brings fresh air into the lungs, while exhalation pushes used air out. This process is part of respiration, which provides oxygen to the body and removes carbon dioxide.
Question 3: What is the process by which living beings remove waste products from their body?
A. Digestion
B. Respiration
C. Excretion
D. Circulation
Answer: The correct answer is option (C).
Explanation: Excretion is the process of removing waste products from the body, such as sweat and urine in animals. Plants also excrete excess water and minerals through small droplets on their leaves.
Question 4: Which of the following shows growth and movement in plants?
A. A sunflower growing taller towards the sunlight
B. A stone lying on the ground
C. Water flowing in a river
D. A book on a table
Answer: The correct answer is option (A).
Explanation: Plants grow in size and can move parts like stems or leaves towards light, a process called phototropism. Growth and movement in plants help them get sunlight and survive in their environment.
Question 5: Which of the following helps animals adjust to their surroundings?
A. Their favourite food
B. Their colour, body shape, and special features
C. The clothes they wear
D. The furniture they use
Answer: The correct answer is option (B).
Explanation: Animals have special features like colour, body shape, claws, beaks, fur, and camouflage that help them survive in their surroundings. These adaptations help them find food, escape enemies, and live comfortably in their habitat.
Question 6: What is the correct sequence in the life cycle of a frog?
A. Egg → Embryo → Tadpole → Adult frog → Froglet
B. Egg → Adult frog → Embryo →Tadpole → Froglet
C. Egg → Embryo → Tadpole → Froglet → Adult frog
D. Tadpole → Egg → Froglet → Embryo →Adult frog
Answer: The correct answer is option (C).
Explanation: The life cycle of a frog starts with eggs, which become embryos and then hatch into tadpoles. Tadpoles grow legs and develop into froglets, which finally mature into adult frogs capable of laying eggs.
Question 7: Which of the following shows a response to a stimulus?
A. A clock ticking
B. A leaf folding when touched
C. A pencil lying on the desk
D. A glass filled with water
Answer: The correct answer is option (B).
Explanation: When a leaf folds after being touched (like in the touch-me-not plant), it shows a response to a stimulus. This is a characteristic of living things, which can sense changes in their environment and react accordingly.
Question 8: Which of the following is not a living thing?
A. Dog
B. Tree
C. Bacteria
D. Chair
Answer: The correct answer is option (D).
Explanation: A chair is a non-living thing because it does not grow, breathe, reproduce, or respond to stimuli. Living things like dogs, trees, and bacteria show life processes.
Question 9: Why do living organisms need food?
A. To look attractive
B. To produce sound
C. To get energy for growth and activities
D. To change their colour
Answer: The correct answer is option (C)
Explanation: Living organisms need food to obtain the energy required for growth, movement, repair, and other life processes. Without food, living things cannot survive or carry out their daily activities.
