Function Of Chloroplast
Beginner’s Guide to the Function of Chloroplast
The main function of chloroplast is to take energy from the sun and turn it into oxygen through the process of photosynthesis. Because of this, plants are basically responsible for all life on earth. Animals do not have chloroplasts, but they are found in every single green plant on the planet. If there were no chloroplasts, there would be no oxygen and human beings would not be able to survive. This is why it is so important to take care of the rain forest and other areas thriving with vital plant life. We all need the oxygen that is provided by the abundant green plants that are growing all over the globe.
What is Photosynthesis?
Photosynthesis is the process by with a plant absorbs energy provided by the sun and turns it into sugars and oxygen. The chloroplast is in the leaves and stems of a plant, and there is a substance known as chlorophyll residing within the chloroplast of a plant. Whenever sunlight comes in contact with the chloroplast, it gives chlorophyll the energy needed to combine carbon dioxide and water. The combination causes a chemical reaction that leads to the production of both oxygen and sugar.
The Photo Function of Chloroplast
Even though it may not seem like it, light energy from the sun is a physical particle – called a photon. Certain kinds of photon particles are attracted to the chlorophyll inside the chloroplast, and this enables the light energy to be absorbed by the plant, which in turn allows the plant to create oxygen.
When the photons are taken in by the chlorophyll, the power they give off causes electrons inside the chlorophyll to attach themselves to a water molecule, splitting it into 2 hydrogen atoms and 1 oxygen atom. This process continues as long as the sun in shining and there is water available. As more oxygen atoms become available, they combine with other oxygen atoms to create molecular oxygen – O2 – also known as the air we breathe.
The Synthesis Function of Chloroplast
Besides creating oxygen, plants are also responsible for producing sugar. Some plants – like sugar cane – create more sugar than others, but all plants are able to convert carbon dioxide into sugar. This is the other part of photosynthesis, which relies on the carbon dioxide that we exhale instead of sunlight.
The production of sugar within a plant is a complex chemical process whereby small parts of the chloroplast known as stroma use carbon dioxide to create sugars that the plant uses to survive. This is how a plant keeps itself alive, and it is also why many plants are used in the production of food for people to eat.
Plants are constantly creating both food – in the form of sugars – and oxygen because of these complex chemical processes that need only sunlight, water and carbon dioxide. It is no wonder that plant life is so vital to the survival of the human race. In most case, plants can survive on their own, without any help from humans. Humans, however, cannot survive without the presence of healthy plant life to provide the air we breathe and the food we eat. This is a basic truth, but it is too often ignored in the name of growth and development. Hopefully it will not be ignored to the degree that it endangers the future of human life on earth.
