How Plants Make and Use Their Own Food

Post  Admin on Wed Oct 19, 2011 3:04 pm

The plants are able to make their own food with the use of the sun’s energy. As the sunlight shines, the layers of cells in the leaf of the plant trap the light energy and captured it. A process in the chloroplast uses water and changes the light energy into a kind of a so called chemical energy. The water that was used earlier in changing light energy to chemical one is separated then by the chlorophyll into hydrogen and oxygen.
The newly transformed chemical energy is stored in the chloroplast. The chloroplast is now ready to use this chemical energy to make food for the plant.
Meanwhile in the stomata, air from the outside environment enters the leaf. This air moves into the tiny spaces around the food making cells inside the body. The Carbon dioxide from the air will pass the cell walls and membranes of the cells. Then the carbon dioxide enters the chloroplast. The chloroplasts use the chemical energy to make a special kind of sugar from the carbon dioxide and hydrogen. From the leaf, the plant carry sugar through their tubes in other parts of the plants such as stems, fruits, roots and so on..
Some other plants changes this stored sugar into the form of starch.
