- What color of light results from the addition of cyan light and red light? green blue white magentaPlants have several leaf pigments, including chlorophyll (green) and beta- carotene (yellow). The reason that beta-carotene is yellow is because beta-carotene: Absorbs all colors of light except for yellow Absorbs yellow light Absorbs all colors of the spectrum Reflects all colors except for yellowTo ensure that the plant was kept at a constant temperature at each light intensity in this experiment: Select one or more: a. the temperature of the room was adjusted to keep the tube of Elodea submerged in water at a constant temperature with a thermometer inside the tube b. the tube containing Elodea submerged in water was surrounded by light on all sides with a thermometer inside the tube c. the tube containing Elodea submerged in water was placed in a water bath with a thermometer in the water bath
- Why do green light waves have less energy than blue light waves?Think of a metaphor or analogy of the light-dependent reactions similar to the “construction analogy”. Make sure to label your diagram and provide a ten-sentence summary that explains your analogy.Rabiya and her group mates are trying to interpret the graph given below during one of their skills sessions. They had previously looked at graphs that showed absorbance plotted over different wavelengths. However, the graph below shows reflectance data (% of light reflected) measured by a STS-VIS spectrophotometer from 400 to 800nm using a regular light source. The average data from white leaves is represented by the dashed red line and average data from green leaves is represented by the solid black line. Obviously, the white leaves do not have the same amount of chlorophyll as green leaves. Note the wavelengths for each color: blue (400-490 nm), green (500-570 nm) and red (640-700 nm). 50 40 10 400 500 600 700 800 Wavelenght (nm) What can be inferred correctly from the reflectance spectrum shown above? O A. White leaves show higher reflectance of green light than green leaves. O B. Green leaves with chlorophyll reflect more light at 500-570nm. O C. There are no peaks so no valid…
- Which color(s) of light does chlorophyll a reflect? a. red and blue b. green c. red d. blueThe 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.THE LIGHT DEPENDEN REACTION MUST OCCUR BEFORE THE LIGHT INDEPENDENT REACTION TRUE OR FALSE?
