GCSE Biology: Photosynthesis and Limiting Factors

Learn about photosynthesis as an endothermic reaction. Covers the word and balanced symbol equations, the concept of limiting factors (light, temperature, carbon dioxide), and the uses of glucose produced by the plant. Includes the method for RP6 (investigating light intensity).

Lesson#1
In this deck, we'll explore photosynthesis, the incredible chemical process that allows plants to make their own food. We will cover the word and symbol equations, explain why it's an endothermic reaction, and investigate the factors that can limit its speed. You'll also learn what plants do with the glucose they produce.
Lesson#2
Photosynthesis is a chemical reaction that takes place inside plant cells, specifically in organelles called chloroplasts. The process uses light energy to convert carbon dioxide and water into glucose and oxygen. Because it takes in energy from the environment, in the form of light, it is known as an endothermic reaction.
Quiz#3
What type of reaction is photosynthesis, because it takes in energy from the surroundings?

endothermic

Lesson#4
The overall process of photosynthesis can be summarised in a simple word equation. The reactants, which are the substances that go into the reaction, are carbon dioxide and water. The products, which are the substances made, are glucose and oxygen. Light energy is needed for the reaction to happen, and this is often written over the arrow in the equation.
Quiz#5
What gas from the air is a reactant in photosynthesis?

carbon dioxide

Quiz#6
What liquid, absorbed by the roots, is a reactant in photosynthesis?

water
