Factors that affect photosynthesis Temperature, light intensity, CO2 levels
Why do plants have stomata? To obtain CO2 from the atmosphere and release oxygen during photosynthesis
What controls the size of the stomata? Guard cells
What are the uses of the xylem & phloem? Xylem: Transports water & mineral ions from the roots up to the leaves Phloem: Carries dissolved sugars from the leaves to the rest of the plant (translocation)
What are plants sensitive to and what types of tropism are involved? Light (phototropism), water (hydrotropism) and gravity (geotropism)
What is auxin? Its a plant hormone that controls phototropism and geotropism.
What sugars do plants produce in photosynthesis and what are these sugars stored as? Glucose and then it's stored as starch.
