  1. Which part of a plant absorbs water and minerals from the soil?

    Answer: Roots

    Roots absorb water and mineral salts from the soil through root hairs, which increase the surface area for absorption.

  2. What is the main function of the leaf in a plant?

    Answer: To make food through photosynthesis

    Leaves are the main site of photosynthesis, where the plant uses sunlight, water, and carbon dioxide to make food (glucose).

  3. Which gas do plants absorb during photosynthesis?

    Answer: Carbon dioxide

    During photosynthesis, plants absorb carbon dioxide from the air and use it along with water and sunlight to produce glucose and oxygen.

  4. What is the role of the stem in a plant?

    Answer: To transport water and nutrients

    The stem transports water and minerals from the roots to the leaves, and food from the leaves to other parts of the plant.

  5. Which of the following is NOT a characteristic of living things?

    Answer: Rusting

    Rusting is a chemical reaction in metals, not a characteristic of living things. Living things grow, respire, and move.

  6. What is the function of the flower in a plant?

    Answer: To carry out reproduction

    Flowers are the reproductive organs of a plant. They contain pollen (male) and ovules (female) needed for reproduction.
