PHOTOSYNTHESIS:
During photosynthesis, light energy is absorbed by CHLOROPHYLL
(found in choloroplasts in most plants and algae)
This energy is used to convert Carbon Dioxide and Water into sugar
(GLUCOSE )
Oxygen is a by productand is released into the atmosphere (this is the
oxygen that we breathe in)
The RATE OF PHOTOSYNTHESIScan be affected by:
*Temperature
*Carbon Dioxide
*Light intensity
The rate can be limitedby shortages of the above^
The glucose produced by photosynthesis is often used for:
*Respiration
*Converted into insoluble starch for storage
*Used to produce fats and oils for storage
*To produce cellulose which strengthen the cell walls
*Used to produce proteins
(To produce proteins, plants also use nitrate ions that absorbed from the
soil)
Venus Fly Traps live in soils with low-nutrient levels and therefore
are adpted to gain their nutrients from the insects and animals that
they eat.
