Lesson details
Key learning points
- Cellular respiration is a chemical process that uses glucose, from food, as a fuel to provide energy for life processes.
- Examples of life processes that require energy from cellular respiration.
- Cellular respiration happens in all living organisms all the time to provide the energy to keep them alive.
- Differences between breathing and respiration.
Keywords
Cell - A cell is the smallest living building block of an organism.
Cellular respiration - Cellular respiration is a chemical process that uses glucose, from food, as a fuel to provide energy for life processes.
Glucose - Glucose is a sugar that our cells use as fuel for cellular respiration.
Breathing - Breathing is the process in which air is moved in and out of the lungs.
Mitochondria - Mitochondria are cell organelles in which cellular respiration takes place in animals and plants.
Common misconception
Thinking that only animals respire, and that plants only photosynthesise (and do not respire).
This lesson uses examples of plants respiring in order to address this misconception.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
