Lesson 2: Photosynthesis and Energy

Photosynthesis

  • Photosynthesis is the process where energy from light is used to make glucose from water and carbon dioxide.
  • Light energy is converted to chemical energy in the form of glucose.
  • In this section, we'll talk about photosynthesis and how it is important.

 

Photoautotrophs

Any animal that photosynthesises is called a photoautotroph (an organism that can make food using light energy).

  • photosynthesis is the same in all photoautotrophs
  • this gives more (indirect) evidence for evolution from a common ancestor
