Photosynthesis experiments using leaf discs objectives: 1 reinforce methods of experimental design and statistical analysis 2 test problem 1: is the rate of photosynthesis higher under bright light than under dim light. Photosynthesis: photosynthesis, process by which green plants and certain other organisms transform light energy into chemical energy from the air to make carbohydrates in photosynthesis over millions of years is being returned at an incredibly rapid rate.
Designing an experiment to testthe rate of photosynthesis lab designed by john s olson based on the floating leaf disk a. A brief outline of various ways to measure the rate of photosynthesis - including measuring photosynthesis via the uptake of carbon dioxide (eg using immobilised algae), via the production of oxygen in pondweed, via the increase in dry mass, and via the production of carbohydrates.
