The characteristic color of the plants is due to some pigments called chlorophyll, which are the main responsible for photosynthesis. This green substance is present in the leaves and stems. In addition, it is found inside the cellular organelles called chloroplasts.
Does sunlight influence the color of a plant?
Sunlight is very rich in photons of red light and less in the more energetic photons, the blue ones. The photons of intermediate energy, of green tonality, are not abundant. The plant pigments are specialized in absorbing that part of the most abundant solar spectrum, the red one, and the most energetic one, the blue one. However, it reflects green light. For this reason, we perceive the leaves of green plants.
What is photosynthesis ?
Photosynthesis is the chemical reaction where carbon dioxide (CO2) and water form sugars and produce oxygen in the presence of light energy. The plants use the sugars produced in photosynthesis as a source of food that is energy for the plant. Under natural conditions, the sun provides the energy to initiate the process of photosynthesis.
Because they are important?
Plants absorb carbon dioxide and water from the environment, use the molecules they need to create glucose and release the oxygen molecules they will not use back into the environment.The roots of the plants not only serve for the absorption of water and food. These help the rain water to enter the earth more easily, directing it towards the deeper layers. In this way, the water is purified through the layers of land until reaching the underground flows, and then to the springs, lakes and rivers.
