Biology: Edexcel IGCSE, topic 2.3.5

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 Investigating Photosynthesis

  • The bubbles used to measure the rate of photosynthesis in pondweed are full of which gas?
