The energy cycle of life

Paragraph 1.6

Mitochondria

• Mitochondria are cell organelles   present in fungal, plant and animal cells.

• Mitochondria breakdown glucose to produce the energy that the cell needs to live.

• This process is called "cellular respiration"

Cellular respiration

• Oxygen is needed to     breakdown glucose.

• Water, carbon dioxide and   energy are formed during   the process

Where does the glucose come from?

• Plants produce glucose via a process called photosynthesis 

• This proces takes place in chloroplasts. Chloroplasts are organelles in plant cells

Do plants cells also perform cellular respiration?

Yes

No

Photosynthesis

• Planten

• Photosynthesis produces glucose end oxygen 

What is the link between cellular respiration and photosynthesis?

What is the link between cellular respiration and photosynthesis?
