FUN WiTH SCIENCE

Science is fun for all.
Follow me in my blog,
you will feel it.
Lets go!

Chapter 1:

Learn about Photosynthesis


Very few plants can actually trap their own food and none can go grocery shopping so plants need to make their food by themselves if they want to eat! Plants are fortunate as they are the only living organisms that can make their own food. How do they do this?
They make their food by combining carbon dioxide gas that is found in air with water and nutrients that they absorb from the soil.
In order to do this though they need energy – which they get from sunlight. The energy from sunlight (solar energy) is used by the plant to make carbon dioxide and water react chemically together and change into glucose (food) and oxygen. This process is called photosynthesis. The word photosynthesis comes from two Greek words: photo meaning light and synthesis meaning putting together so photosynthesis means “putting together with light”.
