The intensity of light is a factor which affects the rate
of photosynthesis. Low light intensity would
produce a low rate of photosynthesis. An increase
in light leads to a higher rate of photosynthesis.
Once the light intensity reaches 10 000 lux, the
photosynthesis rate becomes constant.
1-which plant is more fresh after several days??
2- Why this happen?

Compare the rate of dissolve oxygen for
both of the plant.
Why the both graph keep increasing?
What is the effect of light intensity
towards the rate of photosynthesis?
State the another factor that influence
the rate of photosynthesis?
The plant in the house is wilt while the
plant in the backyard is healthy.
The color of the leaves of taro in the
house turned to brownish after a few
weeks while the taro in the backyard
maintains its green color.
The stem of taro in the backyard is
bigger and taller than the stem of taro in
The results gain is more accurate rather than
using manual method due to the same time
The experiment can be continued for many
hours until the rate of photosynthesis reaching
its optimum level.This experiment is almost
impossible done by traditional method
because students have to sit for many hours to
count the O2 bubbles released by the elodea
The change in photosynthesis cannot be
detected by naked eyes but by using
data logger, we can record the rate of
photosynthesis every one minute per half
Using data logging, we can save the time
by setting up more than one apparatus
can be done simultaneously at the same
