Leaf disk assay experiment

Webleaf disc experiment - Example A leaf disc experiment is a scientific investigation that is used to study the effect of different factors on the rate of photosynthesis in plants. It involves cutting small circular discs out of the leaves of a plant and placing them in a controlled environment, where they can be exposed to different variables such as light intensity, … Webprobably due to the increased leaf area and therefore increased surface area for light absorption. Temperature of the room The experiment will be carried out in a darkened room. The main experiment will be carried in one series of data collections therefore the temperature of the room should remain constant. This will be monitored by
