Q1 (100): What part of the plant anchors it in the soil?
A: The roots.
Q6 (100): What process allows plants to make their own food?
Q11 (100): What three things are needed for photosynthesis?
A: Water, carbon dioxide, sunlight.
Q16 (100): What is a plant adaptation?
A: A trait that helps a plant survive in its environment.
Q21 (100): Define chloroplast.
A: Organelle where photosynthesis happens.
Q2 (200): What part of the plant carries water and nutrients from roots to leaves?
A: The stem.
Q7 (200): What part opens and closes to let gases in and out of a leaf?
A: The stomata.
Q12 (200): What are the products of photosynthesis?
A: Glucose and oxygen.
Q17 (200): Name an adaptation of desert plants.
A: Thick stems to store water or small leaves to reduce water loss.
Q22 (200): What is xylem?
A: Plant tissue that carries water upward from the roots.
Q3 (300): Which plant part is mainly responsible for photosynthesis?
A: The leaves.
Q8 (300): What pigment is essential for photosynthesis?
A: Chlorophyll.
Q13 (300): Where in the plant does photosynthesis occur?
A: In the chloroplasts of leaf cells.
Q18 (300): How do plants in waterlogged soils adapt?
A: Air spaces in roots/stems help oxygen move.
Q23 (300): What is phloem?
A: Plant tissue that carries food from leaves to the rest of the plant.
Q4 (400): Name the plant part that absorbs water and minerals.
A: Root hairs.
Q9 (400): What gas do plants release during photosynthesis?
A: Oxygen.
Q14 (400): Write the chemical formula for photosynthesis.
A: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
Q19 (400): What is tropism?
A: Growth in response to a stimulus (like light or gravity).
Q24 (400): Define transpiration.
A: Water loss from plant leaves.
Q5 (500): What part of the plant makes seeds?
A: The flower.
Q10 (500): Why are vascular tissues important?
A: They transport water and nutrients throughout the plant.
Q15 (500): How does light intensity affect photosynthesis?
A: Higher light increases the rate of photosynthesis up to a point.
Q20 (500): What is phototropism?
A: A plant's growth toward light.
Q25 (500): Define stomata.
A: Small openings on a leaf that allow gas exchange.
