Why do plant leaves look green to us?1. Because pigments in chloroplasts absorb green light, while red and blue light is reflected2. Because pigments absorb red and blue light, while the green light is reflected3. Because pigments absorb red and blue light and green light is emitted from their excited states4. Because pigments in chloroplasts absorb green light, while red and blue light passes through the leaf

Photosynthesis sustains plant growth, and inputs of sunlight sustain photosynthesis. Why, then, do seedlings that germinate in a fully darkened room grow taller than seedlings or the same species that germinate in full sun?
Predict the end result if a chloroplast’s light-, independent enzymes developed a mutation that prevented them from activating in response to light GA3P accumulation ATP and NAD PH accumulation Water accumulation Carbon dioxide depletion
Which of the following is a correct step in the light-dependent reactions of the Z system? a. Light is absorbed at P700, and electrons flow through a pathway to NADP+, the final acceptor of the linear pathway. b. Electrons flow from photosystem II to water. c. NADP+ is oxidized to NADPH as it accepts electrons. d. Water is degraded to activate P680. e. Electrons pass through a thylakoid membrane to create energy to pump H+ through the cytochrome complex.
1) Evolution led to the formation of RuBisCO that is used by C3 plants to fix CO2. Why do you think that it led to an enzyme that also binds to O2 (which causes photorespiration that isn't beneficial to the plant)? 2) Explain what is meant by the statement: "C4 plants separate C3 and C4 processes in space and CAM plants separate C3 and C4 processes in time."
For photosynthesis lab in biology 1) This lab uses spinach leaves. Name another plant that would make an interesting comparison to spinach. Explain why you think this leaf would provide an interesting comparison 2) The lights used in this experiment are 60W. What would you predict the effect of having stronger or weaker wattage bulbs would be on your results? Explain. 3)This lab uses 0.2% sodium bicarbonate. What would you predict the effect of raising or lowering the percentage would be on your results? Explain. 4)What are TWO other things that might be manipulated in an experiment using this same protocol other than the type of leaf, percent sodium bicarbonate, and wattage of light bulb? 5) What key thing do you have to look for on the graph to know for certain that your treatment has caused a significant effect?
1.The shorter the wavelength of visible light the Group of answer choices a, more photons it contains b, less energy absorbed by photosynthetic pigments c, reener the color d, greater the energy 2. The reason we breathe in oxygen is to assist in the production of Group of answer choices a, cell structures b, ATP c, Glucose d, Nitrogen 3. Why does a plant use the CAM or C4 pathway during photosynthesis? Group of answer choices a, To bind carbon dioxide and not use the C3 pathway in photosynthesis b, To bind Carbon dioxide to use later in the C3 pathway when carbon dioxide levels are low due to closed stomata c, Plants that use C4 and CAM do not do photosynthesis d, To use in the process of cell respiration when stomata are closed
If you are planning an experiment to show the effect of light on photosynthesis (i) Will you select white light or green light? Justify your answer. (ii) Why would you select a destarched plant.
1. Thinking about photosynthetic pigments, which statement is correct? A. The pigments found within most types of photosynthesizing cells are primarily chlorophylls and carotenoids. B. The pigments that reflect solar energy are in the membrane of the thylakoid C. Pigments play an important role in the absorption of chemical energy for photosynthesis. D. Leaves contain only one type of pigment and that is the green chlorophyll.
1.Which of the following best describes how light energy is "captured" during the process of photosynthesis? a. The correct photon of light "excites" an electron in a chlorophyll molecule. b. Light heats up the stroma in the center of the chloroplast which causes enzymes to convert CO2 into glucose. c. Photons of light cause H+ to move through the thylakoid membrane, creating a hydrogen ion gradient. 2. What best explains what happens to the electrons that are excited out of chlorophyll molecules during the process of photosynthesis? a.They are pumped across the thylakoid membrane in the ETC of photosynthesis. b. They cause electrons in NADPH to get "excited" and form new bonds in ATP. c. They are captured and move through an ETC, creating ATP and ultimately being captured by NADPH. d. They fall back into the chlorophyll molecule, emitting ATP as they fall.
1. Which of the following does NOT happen during the light-dependent reactions of photosynthesis?A. ATP is producedB. Oxygen is producedC. NADPH is producedD. Glucose is produced 2. The overall source of energy for photosynthesis is:A. energy released when water is split, and oxygen is producedB. energy from NADPHC. light energy from the sun D. energy from ATP 3. John Dela Cruz grew algae in the presence of a poison that stops the lightindependent reactions of photosynthesis. As a result, which molecules will the light-dependent reactions stop producing?A. ADP and NADP+B. ADP and NADPHC. ATP and NADP+D. ATP and NADPH
1. What colour of lights is the least effective in driving photosynthesis? Why?
What are the flaws/is wrong ? n photosynthesis, a plant captures light energy and uses it to transform hydrogen and carbon dioxide into glucose and nitrogen. Photosynthesis occurs inside of a chloroplast. A chloroplast is a double membrane bound organelle that is filled with stroma and has stacks of thylakoid disks called grana. Chlorophyll is the pigment in chloroplasts that allow it to capture light and it absorbs all light except green light. Photosynthesis has two main reactions: the light reactions and the Calvin cycle. The light reactions occur in the stroma. Light is captured by photosystem II and is used to split water into hydrogen and oxygen. This release of energy is passed to the electron transport chain to produce ATP. The remaining energy is passed and more light is captured by photosystem I and is used to make NADPH. The ATP and NADPH move into the thylakoid disks and is used in the Calvin cycle. The Calvin cycle has three stages. In carbon fixation, the enzyme RuBisCO…
