CBSE Class 7 Science Practice Worksheet with Answers
- Explain the process of photosynthesis.
Answer: Photosynthesis is the process by which green plants and other organisms convert light energy into chemical energy. During photosynthesis, plants take in carbon dioxide and water, and using sunlight, convert them into glucose and oxygen. The reaction can be represented by the following equation:
Carbon dioxide + Water + Light energy → Glucose + Oxygen
- Differentiate between prokaryotic and eukaryotic cells.
Answer: Prokaryotic cells are smaller and simpler in structure, lacking a true nucleus and other membrane-bound organelles. They are found in bacteria and archaea. Eukaryotic cells, on the other hand, are larger and more complex in structure, with a true nucleus and various membrane-bound organelles. They are found in plants, animals, fungi, and protists. - What is diffusion? Give an example of diffusion in daily life.
Answer: Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. An example of diffusion in daily life is the aroma of food spreading throughout a room. When food is cooked, the particles in the air near the food have a higher concentration of aroma molecules, while the particles further away have a lower concentration. The aroma molecules move from the higher concentration area to the lower concentration area, resulting in the spread of the smell throughout the room. - How do our sense organs work? Explain with an example.
Answer: Our sense organs work by detecting stimuli in the environment and converting them into electrical signals that can be processed by the brain. For example, the eye detects light and converts it into electrical signals that are transmitted to the brain, allowing us to see. The ear detects sound waves and converts them into electrical signals that are transmitted to the brain, allowing us to hear. - Explain the concept of food chain and food web with suitable examples.
Answer: A food chain is a series of organisms in which each organism is eaten by the next organism in the chain. For example, in a grassland ecosystem, a grasshopper eats grass, a mouse eats the grasshopper, a snake eats the mouse, and a hawk eats the snake. A food web is a more complex representation of the feeding relationships in an ecosystem, showing the interconnectedness of various food chains. For example, in a forest ecosystem, a caterpillar eats leaves, a bird eats the caterpillar, a snake eats the bird, and a fox eats the snake. Additionally, the bird might also eat insects and seeds, and the fox might also eat other small mammals.
- What is the function of blood in our body? Explain.
Answer: The blood in our body serves several important functions. It carries oxygen from the lungs to the body’s tissues and organs, and carries carbon dioxide back to the lungs to be exhaled. It also carries nutrients and hormones throughout the body, and helps to remove waste products from the body. Additionally, blood plays a role in the body’s immune system, helping to fight off infections and diseases. - How does a volcano form? Explain.
Answer: A volcano forms when magma from beneath the Earth’s surface rises and collects in a magma chamber. When the pressure from the magma builds up, it causes an eruption, and the magma is ejected onto the Earth’s surface. As the magma cools and solidifies, it forms a cone-shaped mountain, with a central vent or crater through which the magma and gases are ejected. - What is the process of respiration? Explain.
Answer: Respiration is the process by which living organisms release energy from the food they eat. The process involves inhaling oxygen and exhaling carbon dioxide. The oxygen is used by the body to break down the food into simpler substances, which releases energy. The carbon dioxide produced in the process is expelled out of the body. - What is the difference between a physical change and a chemical change?
Answer: A physical change is a change in the physical properties of a substance, such as its shape, size, or state, without changing its chemical composition. A chemical change, on the other hand, is a change in the chemical composition of a substance, resulting in the formation of a new substance. - What is the difference between reflection and refraction of light?
Answer: Reflection is the bouncing back of light when it strikes a surface, while refraction is the bending of light as it passes from one medium to another. Reflection occurs when the light rays hit a smooth surface, while refraction occurs when the light rays pass through a medium of varying density. - What is an ecosystem? Explain with an example.
Answer: An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with each other and their physical environment. An example of an ecosystem is a forest, where different types of plants and animals interact with each other and the physical environment, such as soil, water, and air. - What is the difference between renewable and non-renewable resources?
Answer: Renewable resources are resources that can be replenished or regenerated naturally, such as solar energy, wind energy, and biomass. Non-renewable resources are resources that are finite and cannot be replenished, such as fossil fuels (coal, oil, and natural gas).
