1st question: 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. The plant will die because the damage caused by the construction paper circles prohibited photosynthesis to occur at all. Skip to navigation

(Please Answer Both)
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.

Answer 1

1st question: The answer choice that best explains 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."

2nd question:
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 such as glucose 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 usable carbon molecules for the plant and releases oxygen back into the atmosphere.

Answer 2

1st question: Based on the given information, 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."

2nd question: Fill in the blanks with the answers from the science 7 a photosynthesis portfolio 2:

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, the reactants carbon dioxide and water combine to form products 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 usable carbon molecules for the plant and releases oxygen back into the atmosphere.

Answer 3

1) Based on the information provided, we can determine that the areas that were covered by the construction paper circles on the leaves of the plant experienced a lack of sunlight, causing a change in color. However, once the plant is put back in the sun without the paper circles attached, those areas will now be able to absorb sunlight energy into the chlorophyll contained in the chloroplasts. This will enable photosynthesis to occur in those areas, and eventually, the green color will return to those parts of the leaves. 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."

2) The process of photosynthesis requires an energy input from sunlight. In this reaction, carbon dioxide and water combine to form chemical products such as carbon-based organic molecules and oxygen. Therefore, the correct answers to fill in the blanks are as follows:

Reactants: carbon dioxide and water
Products: carbon-based organic molecules and oxygen
