Q:

Where does most photosynthesis take place?

A:

Quick Answer

Most photosynthesis takes place in the leaf of plants in the chloroplasts. The chloroplasts contain a green pigment called chlorophyll that is responsible for absorbing sunlight that hits the leaf.

Full Answer

The primary function of chloroplasts is to take the sunlight absorbed from the chlorophyll and turn it into usable energy, adenosine tri-phosphate (ATP) and NADPH, before storing it for future use. The chloroplasts are also responsible for many secondary functions, such as creating fatty acids and amino acids. Finally, they are also a key component of the plant's immune response. Chloroplasts are only created as a result of cell division.

  • Q:

    Where do the light independent reactions of photosynthesis take place?

    A:

    The light-independent reactions of photosynthesis take place in the stroma of the chloroplasts. These are the same organelles where the light-dependent reactions of photosynthesis take place, but those happen in a different part of the chloroplast: the thylakoid membrane.

  • Q:

    Where do light-dependent reactions take place?

    A:

    Light-dependent reactions take place in the chloroplasts of plants that use photosynthesis to make sugar. The process of making sugar requires two distinct reactions: a structure called the thylakoid membrane is responsible for the light-dependent reactions, while the stroma conducts the light-independent reactions.

    Why don't onion cells have chloroplasts?

    A:

    Onion cells lack chloroplasts because the onion is part of the plant that is not involved in photosynthesis. The part of the plant eaten by humans is called the bulb, and it resides at the base of the plant. The bulb’s primary purpose is energy storage and holding the flower for the second growing season. Growing near the ground, the bulb is in poor position to collect sunlight.

  • Q:

    Why is sunlight needed for photosynthesis?

    A:

    Sunlight is needed for photosynthesis because the solar energy is what is converted to chemical energy by the plant's chloroplasts. This energy is necessary for the production of glucose, which provides usable energy for the plant.
