1. What is it??
Why do we need it??

2. Photosynthesis
• A process that converts carbon dioxide into
organic compounds

3. In other words:
• The chemical process by which plants capture
sunlight and use it to convert carbon dioxide
and water into food.

4. • Green plants
– Flowers
– Trees
– Some algea
– A few various forms of bacteria
**Mostly flowers and trees**

5. • These include:

6. • The plants/algea/bacteria
• Other living beings such as animals
• Even humans!!

8. Stomates
• Microscopic hole in the stem and leaves
of plants
• This is where carbon dioxide enters the
plant

10. After being absorbed by the
roots:

11. • Contained in the plant
• This is what makes the green color

12. What does chlorophyll do besides
make the plant green??
When sunlight falls on the
plant, the chlorophyll
captures the energy in it,
and stores it for further
use.

14. This is combined with the carbon
dioxide to produce the food for the
plant

15. The oxygen is let out through the stomates

17. We use the oxygen produced by this to fulfill
our oxygen intake to live.

18. • Proteins
• Fats
• Water soluble sugars

21. Sunlight, water, and the plants
work together to supply the raw
source of energy to us and help us
breathe in oxygen to live on.

22. Life without
photosynthesis would
be impossible!!!
