A student conducted a scientific experiment with a plant. She cut out three 1-inch circles from construction paper and attached each circle to a different leaf of the plant. Finally, she set the plant in front of a sunny window with good air flow and left it there. She made sure that the plant was given enough water during her experiment. After 2 days, she removed one of the circles; after 4 days, she removed another circle; and at the end of the week, she removed the last circle.%0D%0A%0D%0AHere are her results:%0D%0A%0D%0ADay 2: slight mark where the paper covered the leaf; it is a lighter green than the rest of the leaf.%0D%0A%0D%0ADay 4: yellow circle where the construction paper was.%0D%0A%0D%0ADay 7: almost white circle where the paper covered the leaf.%0D%0A%0D%0AUsing your knowledge of photosynthesis, which answer choice explains what most likely will happen to those leaves once the plant is put back in the sun without the construction paper circles attached?%0D%0A%0D%0A(1 point)%0D%0AResponses%0D%0A%0D%0AThe plant will die because the damage caused by the construction paper circles prohibited photosynthesis to occur at all.%0D%0AThe plant will die because the damage caused by the construction paper circles prohibited photosynthesis to occur at all.%0D%0A%0D%0AThose leaves will fall off and the rest of the plant will continue to grow and perform photosynthesis.%0D%0AThose leaves will fall off and the rest of the plant will continue to grow and perform photosynthesis.%0D%0A%0D%0AThose areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return.%0D%0AThose areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return.%0D%0A%0D%0AThe rest of the plant will develop yellow or white circles just like the leaves that had the construction paper circles on them and photosynthesis will not occur in those areas even though the sunligh energy is being absorbed by the chlorophyll contained in the chloroplasts.%0D%0AThe rest of the plant will develop yellow or white circles just like the leaves that had the construction paper circles on them and photosynthesis will not occur in those areas even though the sunligh energy is being absorbed by the chlorophyll contained in the chloroplasts.%0D%0ASkip to navigation
The correct answer is:
Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return.
Based on the provided information, the most likely outcome is that those areas of the leaves that were covered by the paper circles will now be able to absorb sunlight energy into the chlorophyll contained in the chloroplasts. As a result, photosynthesis will occur in those areas, and the green color will eventually return.
To understand why this is the most likely outcome, let's break it down:
1. Photosynthesis: Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose (energy) and oxygen. It occurs in the chloroplasts, which contain a green pigment called chlorophyll.
2. The effect of the construction paper circles: By covering the leaves with construction paper circles, the student effectively blocked sunlight from reaching the covered areas. Sunlight is a critical component for photosynthesis to occur.
3. Day 2: On day 2, the student observed a slight mark where the paper covered the leaf. This is an indication that some level of photosynthesis occurred, but at a reduced rate due to the blockage of sunlight. The lighter green color suggests less chlorophyll production.
4. Day 4: On day 4, the student observed a yellow circle where the construction paper was. This color change indicates that photosynthesis was further limited, as chlorophyll production was likely reduced or halted in the covered areas.
5. Day 7: By day 7, the student observed an almost white circle where the paper covered the leaf. This suggests that photosynthesis was severely inhibited in those areas, resulting in a loss of chlorophyll and the green color associated with it.
6. Put back in the sun without the paper circles: Once the construction paper circles are removed and the plant is put back in the sun, the previously covered areas will now receive direct sunlight. This will allow the chlorophyll-containing chloroplasts to absorb the sunlight energy and resume photosynthesis.
7. Green color restoration: With the availability of sunlight, the previously covered areas will be able to produce chlorophyll again, leading to the restoration of the green color. As photosynthesis continues, the plant will regain its normal functioning and growth.
Based on this understanding, the correct answer is: "Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return."
Based on the given information and knowledge of photosynthesis, the most likely explanation for what will happen to the leaves once the plant is put back in the sun without the construction paper circles attached is:
- Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts.
- Photosynthesis will occur in those areas, and the green color will eventually return.
So, the correct answer is:
- Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return.
