About Photosynthesis

Photosynthesis is a process which happen in the plants, algae, and some bacteria. Those photosynthetic organisms (named autotrophs) utilize the energy of the sun to convert CO2 (carbon dioxide) into organic compounds, such as carbohydrates. An example of carbohydrates will be sugars such as glucose, galactose or mannose.

Photosynthesis by those organisms is crucial for life on Earth. They take in CO2 (carbon dioxide),which are waste products from the animals and humans, and make O2 (oxygen) so that we are able to breathe. But, there are certain bacteria which do anoxygenic photosynthesis, meaning that they consume CO2 (carbon dioxide), but do not release O2 (oxygen).

The process of photosynthesis

The process of photosynthesis happens through:

  1. Light reactions, that contain Photosystem I and Photosystem II. During the light reactions, energy from light is utilized to make ATP and NADPH, that are utilized to give energy for the creating of glucose, in an example. During the dark reactions, CO2 (carbon dioxide) is synthesized into glucose, starch and sucrose.
  2. Dark reactions happens through the Calvin-Benson-Bassham cycle, that results in CO2 fixation.

Where the Process of Photosynthesis Occurs: The Chloroplast

The chloroplasts are organelles in plants that crop light energy to produce ATP and solve carbon dioxide in eukaryotic photosynthetic cells. Chloroplasts exist in green plants are globular or discoid. They have a dual membrane system.

Here are the important features of the chloroplast:

  • Chlorophyll
    Chlorophyll is a pigment which absorbs light in the blue and red wavelengths. It appears green to our eyes. For your information, the main kinds of Chlorophyll are chlorophyll a and chlorophyll b.
  • Thylakoid membranes
    It is where the chlorophyll that are carriers for electron transport and are the components for synthesis of ATP and NADPH are stored.
  • Thylakoids
    They are flattened sacs made up of an extensive network of the membranes.
  • Stroma
    It is the fluid matrix of the chloroplast. Also, it is analogous to the cytoplasm of a cell.
  • Grana
    These are stacks of thylakoids. They look poker chips stacked up.
  • Lumen
    It is the inside of a thylakoid.
  • Lamella
    It is the linkage between one thylakoid in a granum to another.
  • Photosystems
    These are light-capturing units of the thylakoid membrane.
