WebInvestigating photosynthesis – starch and chlorophyll. During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is: transported to the growing parts of the plant for use in respiration; transformed into cellulose, proteins and oils WebIn order to measure the rate of photosynthesis, we look at the amount of oxygen that a plant can produce, whilst changing one factor (e.g. light intensity). For example with this …
WebThere are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen output; ... Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. Carbon dioxide concentration ... GCSE Subjects GCSE Subjects. Art and Design; Biology ... WebLeaves with more chlorophyll are better able to absorb the light required for photosynthesis. The compensation point. These graphs have been plotted with rate of photosynthesis …
