    What is chloroplast?

    Contains chlorophyll for photosynthesis.

    What is chlorophyll?

    Absorbs sunlight to convert CO2 and water into glucose.

    What defines photosynthesis?

    Produces glucose and oxygen using sunlight, CO2, and water.

    What are the conditions of photosynthesis?

    Requires chlorophyll, sunlight, CO2, and water.

    What is respiration?

    Breaks down glucose to release energy as ATP.

    How is glucose tested in plants?

    Benedict's solution turns orange if glucose is present.

    How is starch tested in leaves?

    Iodine solution turns blue-black if starch is present.

    What is destarching?

    Removes starch by keeping plants in darkness.

    Is chlorophyll needed for photosynthesis?

    Yes, it is essential for food production in plants.

    Why is carbon dioxide necessary for photosynthesis?

    It is a raw material needed to produce glucose.

    Why is light necessary for photosynthesis?

    Light energy is required for starch formation.

    How is oxygen produced during photosynthesis?

    Bubbles of gas are released from plants in sunlight.

    Why is photosynthesis important?

    Provides food and oxygen, maintaining life on Earth.

    What factors affect the rate of photosynthesis?

    Light intensity, temperature, CO2 concentration, water, chlorophyll.

    What is a limiting factor in photosynthesis?

    Any condition that restricts the rate of photosynthesis.

    How are glucose and oxygen useful products of photosynthesis?

    Glucose provides energy; oxygen supports respiration.

    What is the effect of temperature on photosynthesis?

    Increases rate until enzymes are denatured above 40°C.

    How can carbon dioxide concentration be increased in a greenhouse?

    By adding sodium hydrogen carbonate to water.

    What is a leaf?

    The site where photosynthesis occurs.

    What is the function of stomata?

    Allow gas exchange for photosynthesis and respiration.

    How do guard cells control stomata?

    They open and close stomata based on water levels.

    What are the main differences between respiration and photosynthesis?

    Respiration breaks down food; photosynthesis creates it.

    When do carbon dioxide and oxygen move in opposite directions?

    At night, during respiration in the absence of light.

    What are plant nutrients?

    Mineral salts needed for healthy plant growth.

    What are symptoms of nutrient deficiencies in plants?

    Stunted growth, yellow leaves, poor root growth.

    What are fertilizers?

    Compounds that provide missing nutrients to plants.

    What is a natural fertilizer?

    Includes farmyard manure and compost, enriching soil.

    What are the advantages of natural fertilizers?

    Cheap to make and less harmful to the environment.

    What are the disadvantages of artificial fertilizers?

    Risk of water pollution and requires careful usage.
