How Plants Grow

Learning how plants grow is a very important concept as it creates the life that surrounds us. Without plants, there would be no greenery. Trees, grass, and flowers would no longer exist. These are the things we take for granted almost everyday. It is important to understand how plants survive and create food for themselves.

Plants grow through the process of Photosynthesis. Photosynthesis converts light energy from the sun into chemical energy that the plant can use to grow. Photosynthesis can differ slightly between different species of plants. But the process is very similar. Almost every environment that a plant lives in contains sun light. Sun light is the key to plants growth and energy.

Over time, plants have learned to evolve to process energy differently. In the beginning of time, plants probably evolved very early, and used hydrogen instead of water. Hydrogen was a much more abundant resources many years ago when our planet was still forming. Without this evolutionary process, our planet would not have turned into a livable environment that we call home.

A Chloroplast is probably the most important part of the photosynthesis process. An average plant cell will contain approximately 10-100 chloroplasts. Each chloroplast is enclosed by a membrane. These Chloroplasts, convert the light energy into energy used to fuel the plants functions.

The efficiency of photosynthesis can be measured with today's technology. Plants currently convert light into chemical energy with an efficiency of about three to six percent. The absorbed light that is not converted into energy is removed by the plant in the form of heat. Plants remove about one to two percent of unused absorbed light. This is a very small fraction compared to how much light plants use to function.

Different species of plants can be found almost anywhere on earth. You can find plants in water, on land, and cold places where you didn't think it was possible for life to grow. The reason for this is that plants have learned to adapt and evolve over millions of years to stay alive and not become extinct. Since almost all plants use light to survive, it is an extremely important resource that even us humans need every day. Without light, photosynthesis does not occur leaving plants with no source of food that they need to survive.
