6O2 + C6H12O6 6C02 + 6H2O+ 36ATP

Cellular Respiration

What are plants used for

How many different uses of plants can you spot?

What are plants used for?

How do plants get the food they need

How do plants get the food they need?

All living organisms need food to grow and survive.

This is because food provides raw materials for growth and energy for chemical reactions.

Plants are known as producers because they provide food for many other organisms.

Without plants, other organisms would have no raw materials for growth or energy.

Unlike animals, plants cannot move very much, so how do they get the food that they need?

Do plants eat soil

Do plants eat soil?

It used to be thought that plants got their food from the soil.

This was proved to be untrue by measuring the mass of the soil in a plant pot before and after growth.

The soil did not decrease in mass, even though plant mass increased.

Later experiments showed that plantsactually make their own food!


This means that all other organisms rely on plants.


The Sun is the source of energy for almost all life on Earth

Light energy from the Sun is captured by plants and other photosynthetic organisms, and converted into stored chemical energy.


Plants make their own food by photosynthesis.

This process is a chemical reaction that uses light energy.

light energy

The word photosynthesis comes from the Greek language:

  • ‘photo’ means ‘light’

  • ‘synthesis’ means ‘putting together’

Photosynthesis just means ‘putting together with light’.


Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is captured by chlorophyll and is used to convert carbon dioxide and water into glucose and oxygen.


6 CO2 + 6H2O + Light C6H12O6 + 6O2

Carbon Dioxide + Water + Sunlight Glucose + Oxygen


Photosynthesis and Cellular Respiration (Aerobic Respiration)

Common set of molecules

Common Set of molecules

Both photosynthesis and cellular respiration recycle common set of chemicals: water, C02, O2, and glucose.

Plants use energy from the sun light to rearrange the atoms of water and carbon dioxide, producing glucose and oxygen.

Oxygen is used both and plant and animal cells during cellular respiration to release energy stored in glucose….enables cells to produce ATP.
