Quick Answer

Chlorophyll’s function in plants is to absorb light and transfer it through the plant during photosynthesis. The chlorophyll in a plant is found on the thylakoids in the chloroplasts.

Full Answer

Chlorophyll uses sunlight to make sugar. It’s the key substance within chloroplasts, which are the food production centers of a plant cell. Sunlight hitting chloroplasts in plants is absorbed by chlorophyll and then combined with carbon dioxide and water to create glucose, or sugar. This process also creates oxygen, which animals use in their own respiration. Mitochondria then use the sugar produced by the chlorophyll to convert it into energy that’s usable by the plant. The stroma regulate the carbon dioxide intake of the plant, which is critical to the whole process.

Chlorophyll is also not the only structure that uses light. Algae has phycoerythrin, and brown algae uses fucoxanthin.

Chlorophyll absorbs all sunlight colors besides green, which is why they appear green to the human eye. The green light is what’s being reflected. Leaves slowly lose their chlorophyll during the fall months because trees shut down their photosynthesis processes because there won’t be enough sunlight to complete the process, and they need to conserve energy. As the green from chlorophyll fades away, the yellows and oranges that were in the leaves all along are then seen due to food stored in the leaves.

  • Q:

    Which organelle is responsible for photosynthesis?

    A:

    Chloroplasts are the organelles found in plant cells that contain chlorophyll and undergo photosynthesis. The chlorophyll pigments found in the chloroplasts are the main pigments utilized in photosynthetic reactions.

  • Q:

    What are the starting materials for photosynthesis?

    A:

    The starting materials for photosynthesis are carbon dioxide, water and sunlight. Green plants have special cell structures called chloroplasts that contain a green pigment called chlorophyll. When chlorophyll is excited by sunlight in the presence of carbon dioxide and water, green plants are able to synthesize carbohydrates through photosynthesis.

  • Q:

    What is the purpose of photosynthesis?

    A:

    Photosynthesis is a process that allows plants to harvest energy in sunlight and store it chemically, by producing sugars. Sugars hold energy in their molecular bonds; when the plant breaks down these bonds, energy is released that the organism can then use. Although green plants are the most famous photosynthesizing organisms, some bacteria, algae and protists carry out the process as well.

  • Q:

    What is the function of grana?

    A:

    The granum supports the process of photosynthesis in plants due to the fact that it is composed of chlorophyll and phospholipids. Grana, which is the plural form of granum, refers to a stack of thylakoids contained within the chloroplasts of plant cells.
