Testing the Rate of Photosynthesis
Science: KS3, topic 1.5.5
Measuring the Rate of Photosynthesis
The rate that pond weed produces bubbles indicates the rate of photosynthesis. The bubbles released are oxygen, a waste product of photosynthesis.
Test yourself on Testing the Rate of Photosynthesis
Light intensity can affect the rate of which process in plants such as pondweed?
The bubbles used to measure the rate of photosynthesis in pondweed are full of which gas?
A student counts 10 bubbles per minute with the lamp 20 cm from the pondweed. She moves the lamp to 10 cm away and now counts 18 bubbles per minute. What can she conclude?
