Unit 1: combustion and breathing

At the end of lesson 

... you can explain how plants hold energy in glucose during photosynthesis.

... you can explain that breaking down glucose releases energy.

During the instruction 

Make notes in a notebook :)

Where do get our energy from? 

How do plants create the energy from the sunlight?

How do plants create the energy from the sunlight?

• water + CO2+ sunlight → glucose + O2
  

• converting substances into other substances = metabolism

How does energy come free?

Glucose can be broken down. This happens in the mitochondria.​

Important! Both plant and Animal Cells have mitochondria. 

​Energy comes free when glucose is broken down. This process is called combustion.
