Volumeter B was in the light. One floats on water; the other sinks. You may be wondering, why does chlorophyll absorb and reflect light? What would you expect to happen if you compare the rate of photosynthesis in bright white light and in darkness? What role does the pigment play in the light reactions? Chloroplasts contain an abundance of saclike photosynthetic membranes called thylakoids. Chlorophyll, a light-sensitive pigment, is found in many of these membranes. During carbon fixation, a 6-carbon compound is formed which immediately splits into two ___a___ molecules known as ___b___. Chlorophyll B absorbs blue light. Chlorophyll absorbs certain wavelengths of light and reflects green light. Chlorophyll's electrons absorb the energy from the sun. However, the overall reaction doesn't indicate the complexity of the chemical reactions or the molecules that are involved. When C4 photosynthesis produces four-carbon intermediate compounds, carbon dioxide and three-carbon compounds are formed. Most leaves appear green because the chloroplasts in plant cells give plants their green color. A. The accessory pigments absorb light that is not absorbed by chlorophyll-a. As a waxyorganic compound, chlorophyll is not soluble in water. What is the overall purpose of photosynthesis? Why is sunlight needed in photosynthesis? The level of liquid in the volumeter went up because the plant was producing oxygen during photosynthesis. The chloroplasts use photosynthetic chlorophyll pigment and take in sunlight, water, and CO2 to produce glucose and oxygen. The two most common types of chlorophyll are chlorophyll a, which is a blue-black ester with the chemical formulaC55H72MgN4O5, and chlorophyll b, which is adark green ester with the formula C55H70MgN4O6. The level of liquid went down because the plant was using up the available oxygen in the water. Carbon Dioxide plays a big role in the Light-Independent phase of photosynthesis. Chlorophyll is a pigment found in the chloroplasts of plants that absorbs the wavelengths of light required to convert water and carbon dioxide into chemical energy during photosynthesis.
