In this lesson, we will learn about the process of photosynthesis, the photosynthesis equation, factors that affect the rate of photosynthesis, how the leaf is adapted to photosynthesis and how to set up an experiment to investigate photosynthesis.
Describe the process of photosynthesis and understand its importance in the conversion of light energy to chemical energy.
2.18 Photosynthesis Equations
Recall the word equation and the balanced chemical symbol equation for photosynthesis.
2.19 Factors affecting the rate of photosynthesis
Understand how carbon dioxide concentration, light intensity and temperature affect the rate of photosynthesis.
2.20 Leaf adaptations to photosynthesis
Explain how the structure of the leaf is adapted for photosynthesis.
2.21 Mineral uptake in the roots
Recall that plants require mineral ions for growth and that magnesium ions are needed for
chlorophyll and nitrate ions are needed for amino acids.
2.22 Evolution of Oxygen during photosynthesis
Describe simple controlled experiments to investigate photosynthesis, showing the
evolution of oxygen from a water plant, the production of starch and the requirements of
light, carbon dioxide and chlorophyll
