PHOTOSYNTHESIS
By Sarah Mulia
Photosynthesis is the process by which plants
use sunlight, water, and carbon dioxide to
create oxygen and energy in the form of sugar
FACTORS THAT AFFECT
PHOTOSYNTHESIS
Sunlight or Light intensity
rate of reaction of photosynthesis will be faster in presence of light and will be slow down
in the dark.
FACTORS THAT AFFECT
PHOTOSYNTHESIS
Concentration of Carbon Dioxide
the more carbon dioxide a plant is given, the faster it can photosynthesis up until the
maximum is reached.
FACTORS THAT AFFECT
PHOTOSYNTHESIS
Temperature
chemical reactions increases as the temperature increase until reach the optimum
temperature and next rate of photosynthesis will decreases as the temperature increases
IMPORTANCE OF PHOTOSYNTHESIS
basic reaction to

constant global
level of oxygen

produce oxygen
for respiration
to reduce level of
carbon dioxide in
the atmosphere
