Chlorophyll: responsible for the green color of plants

What is (definition)

Chlorophyll is a group of photosynthetic pigments present in chloroplasts (organelles present in plant cells and algae, rich in chlorophyll), responsible for the green coloration of plants.

Main characteristics of chlorophyll

Its molecular structure is similar to that of hemoglobin (the protein responsible for blood staining, which contains iron and carries oxygen throughout the body through red blood cells), the difference being that hemoglobin has iron instead of magnesium.

Within plant cells, chlorophyll is found within chloroplasts surrounded by dense protoplasm bodies (the albuminoid substance that makes up the active and living part of the cell).

Chlorophyll's intense green color is due to its enormous ability to absorb light through the blue and red regions of the electromagnetic spectrum; Because of these absorptions, the light it reflects and transmits is the green we perceive.

Due to their tendency to mask the presence of the colors of other substances, such as carotenoids (red or yellow pigment found in plants and animals), the predominant color in plants is green.

As the amount of chlorophyll present in plants decreases, the other colors begin to appear. This effect becomes quite noticeable during autumn, the time of year when tree leaves change color.

Another very important feature of chlorophyll, is its ability to transform sunlight energy into chemical energy, this is through the process of photosynthesis, in which the energy absorbed by chlorophyll transforms carbon dioxide and water into carbohydrates and oxygen.
