PHOTOSYNTHESIS
What is it??Why do we need it??
By: Shyla Turner *** Instructional Technology TR 9:30-10:45***
Photosynthesis
• A process that converts carbon dioxide into organic compounds
In other words:
• The chemical process by which plants capture sunlight and use it to convert carbon dioxide
and water into food.
What uses photosynthesis??
• Green plants – Flowers – Trees– Some algea– A few various forms of bacteria
**Mostly flowers and trees**
Most essential components of photosynthesis:
• These include:– Direct sunlight– Water– Carbon dioxide – Chlorophyll
Who benefits from photosynthesis?
• The plants/algea/bacteria
• Other living beings such as animals
• Even humans!!
Parts of Photosynthesis
Stomates• Microscopic hole in the stem and leaves
of plants
• This is where carbon dioxide enters the plant
At the same time, water is
entering the plant through
the roots.
After being absorbed by the roots:
The water travels all the way through the stem to reach
the leaves.
Chlorophyll
• Contained in the plant
• This is what makes the green color
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.
This energy is eventually
used to convert water into
hydrogen and oxygen.
This is combined with the carbon dioxide to produce the food for the
plant
Hydrogen
The oxygen is let out through the stomates
OXYGEN
*Hydrogen is used to produce food
*Oxygen is let out as waste product
Photosynthesis is important
in the respiration of humans
and animals
We use the oxygen produced by this to fulfill our oxygen intake to live.
• Proteins
• Fats
• Water soluble sugars
Photosynthesis also produces:
WE DEPEND ON PLANTS (OR ANIMALS THAT FEED ON PLANTS) TO GET THESE BECAUSE OUR BODIES
CANNOT PRODUCE THESE NUTRIENTS ON THEIR OWN
Photosynthesis plays a vital role in regulating the life
cycle on earth!
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.
Life without photosynthesis would
be impossible!!!
