What is active transport and how does it differ from diffusion?
Active transport moves substances against a concentration gradient using energy, whereas diffusion is a passive process where substances move from a high to a low concentration without using energy.
What are the two main functions of phloem in a plant?
Transporting sugars (mainly sucrose) from the leaves to other parts of the plant.
Supporting the plant’s structure.
Explain why the left side of the heart is thicker than the right side.
The left side pumps oxygenated blood around the entire body, requiring more force, whereas the right side only pumps deoxygenated blood to the lungs.
How do stomata help control water loss in a plant?
Stomata open to allow gas exchange for photosynthesis but close to reduce water loss through transpiration.
What is transpiration and why is it important for plants?
Transpiration is the loss of water vapour from plant leaves. It is important because it helps draw water up through the xylem, cooling the plant and transporting minerals.
What role do alveoli play in gas exchange?
Alveoli provide a large surface area for efficient gas exchange, allowing oxygen to enter the blood and carbon dioxide to be removed.
How is oxygen transported in the blood?
Oxygen binds to haemoglobin in red blood cells, forming oxyhaemoglobin, which is transported around the body and released where needed.
Write the word equation for photosynthesis.
Carbon dioxide + Water → Glucose + Oxygen (in the presence of light and chlorophyll).
How does light intensity affect the rate of photosynthesis?
As light intensity increases, the rate of photosynthesis also increases, up to a point where another factor (e.g., CO₂ or temperature) becomes limiting.
What is the function of white blood cells in the circulatory system?
White blood cells help fight infections by producing antibodies, engulfing pathogens, and releasing antitoxins.
