Preparing for the Kerala Teacher Eligibility Test (KTET) Category 3 Natural Science? We have compiled a set of important previous year questions with answers to help you with your preparation. These questions cover various topics in Natural Science, ensuring a thorough revision before the exam.

Here are some sample questions along with their answers:

Which part of the plant conducts photosynthesis?
The leaves of the plant conduct photosynthesis as they contain chlorophyll, which absorbs sunlight for the process.

What is the main function of the xylem in plants?
The xylem is responsible for transporting water and minerals from the roots to different parts of the plant.

Why do fish have gills instead of lungs?
Fish have gills because they extract oxygen from water, whereas lungs are designed for breathing air.

What is the function of the human diaphragm?
The diaphragm helps in breathing by contracting and relaxing to change the pressure in the chest cavity.

Why does a ripe banana taste sweeter than an unripe banana?
A ripe banana contains more simple sugars due to the breakdown of starch, making it taste sweeter.

What is the difference between vertebrates and invertebrates?
Vertebrates have a backbone, while invertebrates do not. Examples of vertebrates include mammals and birds, whereas insects and jellyfish are invertebrates.

How do earthworms help in soil fertility?
Earthworms aerate the soil and decompose organic matter, enriching the soil with nutrients.

Why do some plants have thorns?
Thorns help protect plants from herbivores by making them difficult to eat.

What is the role of the pancreas in digestion?
The pancreas produces digestive enzymes that help break down proteins, fats, and carbohydrates in food.

Why do we get goosebumps when we feel cold?
Goosebumps occur when tiny muscles at the base of hair follicles contract to trap heat and keep the body warm.

What is the function of white blood cells?
White blood cells help the body fight infections by attacking bacteria, viruses, and other harmful invaders.

Why do birds have hollow bones?
Hollow bones make birds lighter, allowing them to fly efficiently.

What is the main function of the large intestine?
The large intestine absorbs water from undigested food and helps in the formation of solid waste.

How do plants reproduce without seeds?
Some plants reproduce through vegetative propagation, where new plants grow from stems, roots, or leaves, such as in potatoes and onions.

Why do camels store fat in their humps?
Camels store fat in their humps as an energy reserve, which they use when food is scarce.

What is the function of the liver in the human body?
The liver detoxifies harmful substances, produces bile for digestion, and helps in metabolism.

Why do leaves appear green?
Leaves appear green because chlorophyll absorbs red and blue light but reflects green light.

What happens during respiration in plants?
During respiration, plants break down glucose to release energy, which is used for growth and other functions.

Why does sweating help in cooling the body?
Sweating cools the body as the evaporation of sweat removes heat from the skin.

What is the difference between warm-blooded and cold-blooded animals?
Warm-blooded animals maintain a constant body temperature, while cold-blooded animals depend on their environment for temperature regulation.

How do fungi obtain their food?
Fungi absorb nutrients from decomposing organic material since they do not have chlorophyll for photosynthesis.

Why do bats use echolocation?
Bats use echolocation to navigate and find food in the dark by emitting sound waves and listening to the echoes.

What causes the change of seasons on Earth?
The tilt of the Earth's axis and its revolution around the Sun cause seasonal changes.

How do vaccines work?
Vaccines introduce a weakened or inactive form of a virus to stimulate the immune system and build immunity.

Why do chameleons change color?
Chameleons change color to regulate body temperature and communicate with other chameleons.

What is the difference between renewable and non-renewable energy sources?
Renewable energy sources, such as wind and solar power, can be replenished, while non-renewable sources, such as coal and oil, are limited.

Why do desert plants have thick stems?
Desert plants have thick stems to store water and survive in dry conditions.

What is the role of mitochondria in a cell?
Mitochondria are the powerhouse of the cell, generating energy for cellular activities.

Why do deep-sea fish have large eyes?
Deep-sea fish have large eyes to capture as much light as possible in the dark depths of the ocean.

What is the purpose of the ozone layer?
The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation from the Sun.

Why do amphibians need to stay near water?
Amphibians, such as frogs, need water for reproduction as their eggs and larvae require a moist environment.

What is the main function of the kidneys?
The kidneys filter waste from the blood and regulate fluid balance in the body.

Why do some animals hibernate?
Animals hibernate to conserve energy during cold seasons when food is scarce.

How do bees communicate with each other?
Bees use a dance language to communicate the location of food sources to other bees.

What causes the rusting of iron?
Iron rusts when it reacts with oxygen and moisture, forming iron oxide.

Why do human beings have different blood groups?
Blood groups are determined by the presence of specific antigens on red blood cells, which affect compatibility during transfusions.

How does the digestive system break down food?
The digestive system breaks down food using enzymes and acids in the stomach and intestines.

Why do icebergs float in water?
Icebergs float because ice is less dense than liquid water.

What is the importance of pollination?
Pollination helps in the reproduction of flowering plants by transferring pollen from one flower to another.

Why does sound travel faster in water than in air?
Sound travels faster in water because water molecules are more tightly packed, allowing sound waves to move more quickly.

How do mushrooms grow without sunlight?
Mushrooms obtain nutrients from decaying organic matter rather than through photosynthesis.

What is the role of stomata in plants?
Stomata are small openings on leaves that regulate gas exchange and water loss.

Why do some fruits have seeds while others do not?
Fruits develop from fertilized flowers, but seedless varieties are often produced through selective breeding or mutations.

How do insects breathe?
Insects breathe through tiny openings called spiracles, which allow air to enter their bodies.

Why do some animals have bright colors?
Bright colors in animals can serve as a warning to predators or as a means of attracting mates.

What is the role of red blood cells in the body?
Red blood cells transport oxygen from the lungs to different parts of the body.
