Assertion and Reason Class 10 Biology Chapter 1 Life process
Assertion: Photosynthesis is essential for autotrophic organisms.
Reason: During photosynthesis, autotrophs convert carbon dioxide and water into carbohydrates using light energy absorbed by chlorophyll.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Heterotrophic organisms rely on other organisms for their nutrition.
Reason: Heterotrophs cannot synthesize their own food from inorganic sources and must ingest complex substances that are broken down inside their bodies.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Multi-cellular organisms require specialized tissues for nutrition and respiration.
Reason: Specialized tissues ensure efficient uptake of nutrients and oxygen, and removal of wastes, throughout the organism’s body.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Oxygen is essential for many organisms to break down food and release energy.
Reason: Oxygen participates in oxidising-reducing reactions that break down carbon-based molecules to release energy.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Digestive systems in organisms become more complex as body size increases.
Reason: Complex organisms need specialized structures to efficiently process food and absorb nutrients throughout the body.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Plants store excess carbohydrates in the form of starch.
Reason: Starch serves as an energy reserve that plants can utilize during periods of low sunlight or increased metabolic demand.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Autotrophic nutrition involves the conversion of carbon dioxide and water into carbohydrates using light energy.
Reason: This process occurs in chloroplasts containing chlorophyll, which absorbs light energy for photosynthesis.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Multi-cellular organisms require a transport system to distribute nutrients and oxygen to all parts of the body.
Reason: Specialized tissues for absorption and transport ensure that essential substances are delivered efficiently throughout the organism.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Oxygen is necessary for aerobic respiration in organisms.
Reason: Aerobic respiration involves the breakdown of food molecules to release energy in the presence of oxygen.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: The digestive system of animals includes various specialized organs for breaking down food and absorbing nutrients.
Reason: These organs work together to ensure that complex substances are broken down into simpler molecules that can be used by the body.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Specialized tissues are necessary in multi-cellular organisms to meet the diverse metabolic needs of different cells.
Reason: These tissues facilitate efficient uptake of nutrients and oxygen, as well as removal of wastes, throughout the organism’s body.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Photosynthesis is crucial for the survival of autotrophic organisms.
Reason: During photosynthesis, autotrophs convert solar energy into chemical energy stored in the form of carbohydrates.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Heterotrophic organisms depend on autotrophs for their energy needs.
Reason: Heterotrophs consume autotrophs or other heterotrophs to obtain the organic molecules necessary for their survival.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Oxygen is essential for the breakdown of food molecules in aerobic respiration.
Reason: Aerobic respiration involves the use of oxygen to oxidize organic molecules and generate energy in the form of ATP.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: The complexity of an organism’s digestive system correlates with its dietary habits.
Reason: Herbivores and carnivores have different digestive adaptations to process plant or animal matter efficiently.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Cellular respiration involves the breakdown of carbohydrates and other molecules to release energy.
Reason: This energy is used by cells for various functions, including growth, movement, and maintenance of cellular structures.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: The presence of chloroplasts in plant cells is essential for photosynthesis.
Reason: Chloroplasts contain chlorophyll, which absorbs light energy required for the conversion of carbon dioxide and water into carbohydrates.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Multi-cellular organisms require a circulatory system to transport nutrients, gases, and wastes.
Reason: Specialized tissues and organs are necessary to facilitate the exchange and distribution of substances throughout the organism.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Ingested food undergoes mechanical and chemical digestion in the alimentary canal of animals.
Reason: Digestive enzymes break down complex molecules into simpler forms that can be absorbed by the body.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
Assertion: Nitrogen is essential for the synthesis of proteins and nucleic acids in organisms.
Reason: Organisms obtain nitrogen either as inorganic nitrates/nitrites or as organic compounds derived from atmospheric nitrogen-fixing bacteria.
Answer: Both assertion and reason are correct, and the reason is a correct explanation of the assertion.
