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. Here are her results: Day 2: slight mark where the paper covered the leaf; it is a lighter green than the rest of the leaf. Day 4: yellow circle where the construction paper was. Day 7: almost white circle where the paper covered the leaf. Using 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? (1 point) Responses 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. 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. Those leaves will fall off and the rest of the plant will continue to grow and perform photosynthesis. Those leaves will fall off and the rest of the plant will continue to grow and perform photosynthesis. The 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. The 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. The plant will die because the damage caused by the construction paper circles prohibited photosynthesis to occur at all.

2nd question
Photosynthesis is the Response area reaction by which plants produce complex food molecules (sugars). This process requires an energy input from Response area to occur. In this reaction, the Response area carbon dioxide and water combine to form Response area such as carbon-based organic molecules and oxygen. Photosynthesis is an important part of the carbon cycle because it removes Response area from the atmosphere and through chemical reactions, rearranges the atoms into other forms of useable carbon molecules for the plant and releases Response area back into the atmosphere.

1. Based on the information provided, what is most likely to happen to the leaves once the plant is put back in the sun without the construction paper circles attached?

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.

Photosynthesis is the process by which plants produce complex food molecules (sugars). This process requires an energy input from sunlight to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and oxygen. Photosynthesis is an important part of the carbon cycle because it removes carbon dioxide from the atmosphere and through chemical reactions, rearranges the atoms into other forms of useable carbon molecules for the plant and releases oxygen back into the atmosphere.

2nd question:

Photosynthesis is the biochemical reaction by which plants produce complex food molecules (sugars). This process requires an energy input from sunlight to occur. In this reaction, the molecules carbon dioxide and water combine to form carbohydrates such as carbon-based organic molecules and oxygen. Photosynthesis is an important part of the carbon cycle because it removes carbon dioxide from the atmosphere and through chemical reactions, rearranges the atoms into other forms of useable carbon molecules for the plant and releases oxygen back into the atmosphere.

1st question:

Based on the experiment conducted by the student, it can be concluded that the areas of the leaves covered by the construction paper circles experienced a reduction in chlorophyll content and therefore appeared lighter or yellow. The negative effects of the construction paper circles on photosynthesis were observed. However, once the plant is put back in the sun without the construction paper circles attached, the areas that were covered by the circles will be able to absorb sunlight energy again. This energy will be used by the chlorophyll in the chloroplasts to carry out photosynthesis, resulting in the production of sugars and the eventual return of the green color to those areas. Therefore, the correct answer choice 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.

2nd question:
In the process of photosynthesis, plants use energy to convert carbon dioxide and water into complex food molecules (sugars) and release oxygen. The energy required for this reaction comes from sunlight. During photosynthesis, carbon dioxide and water combine to form carbon-based organic molecules, and oxygen is released as a byproduct. This process is crucial for the carbon cycle as it removes carbon dioxide from the atmosphere and rearranges its atoms into other useful carbon molecules for the plant. Finally, oxygen is released back into the atmosphere.
