phyll has been shown to absorb red light. They choose green light because chlorophyll has been shown to reflect green light. They choose no light as a negative control to examine the rate of synthesis in the absence of light. To measure photosynthetic rate, the scientists use sensors to measure oxygen production of plants exposed to the different light treatments. e the best scientific hypothesis: hotosynthesis is a critical process for plants, and it is of great importance that we understand how it is impacted by different wavelengths of light. rate of oxygen production is higher under red light than it is under green light or no light, it proves that red light has the largest effect on photosynthesis. ecause chlorophyll absorbs red light, rate of oxygen production will be higher for plants exposed to red light than plants exposed to green light or no light.

An experiment was done to determine how color of light and distance affects photosynthetic activity of the pond weed. Pond weed was placed in a test tube containing a solution of sodium hydrogen carbonate, and had its end cut; light was placed 50 cm away and four colors were tested (clear, red, blue, and green). After placing the light, the pondweed was given a certain amount of time to adjust before counting the bubbles, bubbles were counted for 1, 3, and 5 minutes. Only the bubbles that came out of the cut end was counted to represent the rate of photosynthesis. Below is the tabulated results. What are the possible factors or errors that could have affected clear/white light to have lower photosynthetic activity? In theory this should have the highest rate.
The green color of plants is explained by the wavelengths of light that are reflected, transmitted, and absorbed by the chlorophylls in the thylakoids. Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light. Plants appear green because chlorophylls reflect and transmit white wavelength of light, and absorb red and violet-blue wavelengths of light.
Phycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin-responsible for capturing green light, phycocyanin-responsible for capturing orange-red light, and allophycocyanin-responsible for capturing red light. Since light can only penetrate to certain depths in oceans, phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll.

Justify the claim that photosynthetic organisms that live more than 75 feet below the surface of the ocean need phycoerythrin to survive. Provide reasoning that explains this claim.
What is the overall outcome of the light reactions in photosynthesis? NADPH and ATP molecules are produced during the light reactions and are used to power the light independent reactions. NADPH and ATP molecules are produced during the light reactions, which are used to power the light dependent reactions. Sugar and ATP are produced during the light reactions, which are used to power the light independent reactions. Carbon dioxide and NADPH are produced during the light reactions, which are used to power the light dependent reactions.
An experiment was conducted to demonstrate that chlorophyll is essential for photosynthesis. The procedure followed is given below: • A potted variegated plant was destarched. • Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). • A starch test was done on a leaf. • The potted plant was exposed to bright sunlight for 4–5 hours. • After 5 hours, a leaf was removed and tested for starch. How was the potted plant destarched? Explain why all the starch has disappeared during the process Mentioned in QUESTION 1. Describe the steps in the correct sequence that were followed during the starch test. Explain ONE safety precaution that should be taken when testing for starch. Draw a labelled leaf and indicate the colour change in the green and white parts of the leaf, after the second starch test.
