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.

Question 1:
According to the information provided, the most likely outcome once the plant is put back in the sun without the construction paper circles attached is that 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.
Question 2:
In photosynthesis, the reactants are carbon dioxide and water, and the products are carbon-based organic molecules and oxygen. Sunlight is the energy input required for photosynthesis to occur.
1st question:
Based on the information given in the experiment, we can infer that the areas covered by the construction paper circles on the leaves experienced a lack of sunlight exposure. Photosynthesis is the process by which plants convert sunlight energy into chemical energy (sugars) using chlorophyll contained in chloroplasts. With the absence of sunlight in the covered areas, photosynthesis would not occur, leading to a decrease in chlorophyll and a change in color.
The slight mark on the leaf after 2 days indicates that some photosynthesis may still be occurring in that area, although at a reduced rate. The yellow circle after 4 days is a further indication of a decrease in photosynthesis activity. Finally, the almost white circle after 7 days suggests a significant reduction or absence of chlorophyll, resulting in a loss of green color.
Once the plant is put back in the sun without the construction paper circles attached, the areas that were previously covered will be able to absorb sunlight energy again. The chlorophyll contained in the chloroplasts in those areas will activate, allowing photosynthesis to occur. Over time, the green color will return to those areas as they regain their ability to produce sugars through photosynthesis.
Therefore, the answer choice that best explains what will happen to the leaves 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 photosynthesis, the reactants are carbon dioxide (CO2) and water (H2O). These substances combine through the process of photosynthesis to form products, such as carbon-based organic molecules (sugars) and oxygen (O2).
The process of photosynthesis requires an energy input, which is provided by sunlight. Sunlight is essential as it activates chlorophyll in the chloroplasts of plant cells, facilitating the conversion of solar energy into chemical energy through photosynthesis.
Photosynthesis is crucial in the carbon cycle because it removes carbon dioxide from the atmosphere, reducing its concentration, and utilizes it to produce organic molecules (sugars) for the plant's growth and energy storage. Simultaneously, oxygen is released as a byproduct and released back into the atmosphere for other organisms to utilize.
So, the correct answer for the missing words would be:
(products) carbon-based organic molecules
(reactants) carbon dioxide
(energy input) sunlight
