Date:

2. Learning objectives
 To be able to define: respiration
 To understand the role of respiration in animals and plants
 State some uses of energy (ATP)
 Explain the differences between photosynthesis and respiration

3. What is photosynthesis?
 Photo- using light
 Synthesis- to make food

4. Food we eat is ___dig____ to smaller
particles such as glucose, amino acids,
glycerol + fatty acids
These are used for energy
production via reactions
Plants cannot ‘eat’ so they make their
food (glucose) from a process called
__photo_____
This is used for energy
production via reactions
Respiration
This is our food
This is their food

5. What happens to the food we eat?
 After eating our food, smaller molecules like __glu___ are converted to energy that
the body uses
 This is where the phrase ‘food is fuel’ comes from
The energy in organisms is called ATP

6. What happens in plants?
 Similarly, the food made from ____photo____ (___gluc_) is converted to energy
that the plant uses
The energy in organisms is called ATP

7. Food  energy
 Respiration- the chemical reaction where the body uses glucose to release energy (ATP)
 This happens in both animals and plants!

8. Food we eat is ___dig____ to smaller
particles such as glucose, amino acids,
glycerol + fatty acids
These are used for energy
production via reactions
Plants cannot ‘eat’ so they make their
food (glucose) from a process called
__photo_____
This is used for energy
production via reactions
This is our food
This is their food
Energy produced by respiration

9. What is energy (ATP) used for?
Plants:
- Growth
- Movement of ions
Animals:
- Growth and repair
- Movement
- Body temperature
