Photosynthesis is a syntesis process of food to be an energy source in green plant. Photosynthesis can be difinite as a process of making food that happen in the leaf, which done by the chlorophyll and helped by the sun light. There are some factors which influence the photosynthesis process, such as : light, chlorophyll, temperature, carbondioxide, and water.
The light used in photosynthesis is absorbed by a green pigment called chlorophyll. Each food-making cell in a plant leaf contains chlorophyll in small bodies called chloroplasts. In chloroplast, light energy causes water drawn form the soil to split into hydrogen and oxygen.
The sun is the natural source of the light that is utilized by photosynthesis. However, photosynthesis also occurs in the presence of artificial light, like that from an electric bulb. Photosynthesis occurs in outdoor plants only during daylight hours.
The process of photosynthesis, in a series of complicated steps, the hydrogen combines with carbon dioxide from the air, forming a simple sugar. Oxygen from the water molecules is given off in the process. From sugar together with nitrogen, sulphur, and phosporus from the soil-green plants can make starch, fat, protein, vitamins, and other complex compounds essential for life.
Water and carbondioxide which have absorbed will do the photosynthesis process in the leaf. During the photosynthesis they are helped by sun light which find in the green colored pigment, the sun light will break water molecule into oxigen and hidrogen. In one side the oxigen is released to the external air and at the other side the oxigen is used by plant to breath, meanwhile the hidrogen mix with the carbondioxide and form glucose which distributed by vascular floem into the all body of plant.
Photosynthesis is the ultimate source of food and energy for animals and human beings as well as for plants. Animals and human beings eat vegetation whose protoplasm was elaborated from the products of photosynthesis. From this vegetation animals and men obtain the energy that is necessary for their life and growth. The original source of this energy was the sunlight that was converted into the chemical energy of glucose by means of photosynthesis.
So, photosynthesis is an important process that produce oxigen as an air which used by living things to breath, and glucose as a energy source in plant. We can also conclude that Photosynthesis is how plants use light and water to make sugar and It is created in the green parts of a plant and every animal on earth depends on it. So, Without plants we would have no food to eat or oxygen to breath.MOGA BERKAH GAN ......
