Measuring the Rate of Photosynthesis

GCSE: Biology · Combined Science Big enquiry: What changes how quickly photosynthesis happens? Photosynthesis does not always happen at the same speed. A plant may photosynthesise quickly in one set of conditions and…

Factors Affecting the Rate of Photosynthesis

GCSE: Biology · Combined Science Big enquiry: How do carbon dioxide and temperature affect the rate of photosynthesis? On the previous page, Maya used pondweed to investigate how light intensity affects the rate of…

Evidence for What Photosynthesis Requires
