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? plant cover by dark box plant not cover by dark box Plant A Plant B Plant A Plant B
Red line = high light intensity Blue line = low light intensity
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?
Plant in the house Plant at the backyard
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 house.
The results gain is more accurate rather than using manual method due to the same time interval
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 O 2 bubbles released by the elodea plant.
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 an hour.
Using data logging, we can save the time by setting up more than one apparatus can be done simultaneously at the same time.
