Process. = plant cells use light energy to rearrange water and carbon dioxide molecules into sugar . molecules. Oxygen is a by-product (leftover, waste product). Energy now stored in the sugar. Ms. . Albu. B Block. Photosynthesis Lab Findings. We tested the photosynthetic rate of leaf discs of spinach (control) to arugula (experimental) under a 100 watt lamp. Spinach had a higher rate of photosynthesis. 8-1: Energy & Life. What is energy?. The ability to do work.. What is the difference between autotrophs & heterotrophs?. . Autotrophs = make their own food. . Heterotrophs = can’t make their own food; must eat other organisms. What is the . ideal combination of factors . for the . maximum . rate of photosynthesis? . enough light. . enough carbon dioxide. . ideal temperature . (not too hot or cold). How is the rate affected if one of these factors is . Photosynthesis. - a process used by plants and other autotrophs to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. . *It is the way plants make food! . The light-dependent reaction. The light-independent reaction. Required practical 7: . Use of chromatography to investigate the pigments isolated from leaves of different plants, . eg. , leaves from shade-tolerant and shade-intolerant plants or leaves of different colours.. Autotrophs. – organisms use can make their own food. Some. autotrophs capture light energy from the sun in the process of photosynthesis. Heterotrophs. – obtain energy from the foods they consume.
