Q:

Where does the energy for photosynthesis originate?

A:

The energy required for photosynthesis comes from the sun as light energy; plants transform this light energy into chemical energy, or sugars. Plants perform this energy conversion using light, water, carbon dioxide and a green substance called chlorophyll. Photosynthesis takes place in a plant's leaves.

Sunlight includes the full range of colors in the light spectrum. The chlorophyll in plants absorbs the red and some of the blue light waves for use in photosynthesis, and the light waves that are not absorbed are reflected back, giving plants their green color. Another waste product of photosynthesis is oxygen, making plants crucial to the survival of humans.

  • Q:

    When does the Calvin cycle of photosynthesis begin?

    A:

    The Calvin cycle of photosynthesis begins after light energy is transformed into chemical energy by the cells of plants. The adenosine triphosphate, or ATP, molecules created power the Calvin cycle. The Calvin cycle uses the energy to create carbohydrates from water and carbon dioxide.

    What does chloroplast do in a plant cell?

    A:

    In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities integral to life, such as growth and reproduction.

  • Q:

    What makes food for a plant?

    A:

    Plants use a process called photosynthesis to convert light energy from the sun into sugar energy in the presence of carbon dioxide and water. This process takes place in organelles called chloroplasts, which are found in abundance in the leaves of the plant.
