photosythesis experiments
Photosynthesis is the process by which chlorophyll - containing organisms - suchas green plants, algae, and some bacteria - capture energy from light and convert it to chemical energy. For the process of photosynthesis to take place the organism must contain chloroplasts. Chlorophyll is responsible for the green color in plants and is also responsible for their ability to photosynthesize. Photosynthesis is usually carried out in the leaves of green plants, but it can also take place in other parts of the plant such as the stem. The balanced chemical equation for photosynthesis is: Sunlight + 6CO2 + H2O --yields-C6H12O6 + 6O2 The purpose of this lab is to answer the question, "Is sunlight required for photosynthesis?" III.) Experimental Design / Materials and Methods The first experiment was called "Separating Plant Pigments." In this first experiment the materials that you need are a piece of green plant (collard greens), a piece of chromatography paper, solvent, and a test tube. The first thing you do is take your green plant and fold it up tightly. Second, you lay the plant on the chromatography paper and smash parts of the plant onto the paper. Next you mark the outside of the tube with a wax pencil where the bot
proved that photosynthesis did not occur. The plant had to use its stored starch in the ethanol solution and boil it for one minute. Take the leaf out of the plant and boil it for one minute in water. Take it out of the water and place it solution, which is a carbon dioxide indicator, to the test tube nearly to the the light exposed leaf in water for one minute. Next you boil the same leaf in had to use its stored food to survive. Without light the plant could not survive minutes for the see what will happen to the paper. The purpose of this ethanol and place it on a small petri dish and cover it in iodine. The purpose
