Step by step
Solved in 2 steps
- If you landed on a planet where all of the plants had purple leaves, what wavelengths of light would you expect to be least effective for photosynthesis? explain your reasoning.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.If I wanted to maximize the rate of photosynthesis in plants, should I expose them on Low Light or moderate?
- Students are preforming an experiment to study the role of light in photosynthesis. They place an Elodea plant into a large test tube with water and assemble a volumeter using a cork and calibrated glass tubing. Then, the apparatus is placed near a lamp. Soon after, the water level in the tubing begins to move upward. Why does the edge of the water move upward?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?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.
- How would you design an experiment to test the following hypothesis: " The optimal temperature for photosynthesis in spinach leaves is 20 degrees Celsius?"A group of scientists wants to test the effect of different wavelengths of light on plant photosynthesis. They have 3 treatment groups: red light, green light, and no light. They choose red light because chlorophyll 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 photosynthesis 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. Choose the best scientific hypothesis: O Photosynthesis is a critical process for plants, and it is of great importance that we understand how it is impacted by different wavelengths of light. O If 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. O Because chlorophyll absorbs red light, rate of oxygen…(g) The figure given below represents an experiment to demonstrate a particular aspect of photosynthesis. The alphabet 'A' represents a certain condition inside the flask. 2 КОН (i) What is the aim of the experiment ? (ii) Identify the special condition inside the flask. (iii) Name an alternative chemical that can be used instead of KOH. (iv) In what manner do the leaves 1 and 2 differ at the end of the starch test ?
- Both temperature and light intensity can affect the rate of photosynthesis. However, in this study, the investigator kept the temperature constant and only studied how changes in light intensity affected the rate of photosynthesis, Which of the following best explains the investigator's decision to only study light intensity? Select one or more: a. It is easier to control light intensity than it is to regulate temperature, therefore the investigator chose to measure only light intensity b. Light intensity affects the rate of photosynthesis more than temperature, therefore the investigator chose to measure only light intensity c. none of the answers is correct d. If different light intensities and different temperatures had been studied at the same time, it would not be possible to know which of these factors affected the rate of photosynthesis.Assume you want to add an accessory pigment to the photosystems of a plant chloroplast to help it photosynthesize more efficiently. What wavelengths of light would the new pigment absorb? Describe the color of your new pigment. Would this be a useful project for genetic engineers? Explain.In the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100. Which plant (spinach or unknown) has the highest rate of photosynthesis? Explain your answer using evidence, being sure to demonstrate your understanding of the dependent variable.
