Question

Why is the sun needed during photosynthesis? To pull apart carbon dioxide molecules To pull apart glucose molecules To pull apart water molecules

Answer 1

This occurs as a result of photosynthesis in plant

The overall chemical reaction of photosynthesis can be summarized as:

6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

This equation shows that the raw materials for photosynthesis are carbon dioxide (CO2) and water (H2O), which are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy. The role of the sun is to provide the light energy that drives this reaction.

During photosynthesis, light energy is absorbed by the green pigment chlorophyll, which is present in the chloroplasts of plant cells. This energy is used to split water molecules into hydrogen ions (H+) and oxygen atoms. The hydrogen ions are then used to generate ATP (adenosine triphosphate), which is the energy currency of the cell, and to reduce carbon dioxide to glucose.

In summary, the sun is needed during photosynthesis to provide the light energy that is used to split water molecules into hydrogen ions and oxygen atoms, which are then used to generate ATP and reduce carbon dioxide to glucose.

Answer 2

Step-by-step explanation:

The sun is needed during photosynthesis to pull apart water molecules. During photosynthesis, plants use energy from the sun to convert carbon dioxide and water into glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells, where chlorophyll (the green pigment in plants) absorbs sunlight and uses it to convert water into oxygen and hydrogen ions.

The hydrogen ions then combine with carbon dioxide to produce glucose, which is used by the plant as food. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

Therefore, the sun's energy is essential for photosynthesis to occur, as it is the source of the energy that is used to split apart the water molecules into hydrogen ions and oxygen. Without the sun, photosynthesis would not be able to take place, and plants would not be able to produce the glucose they need to survive.
