Plants are mainly grown and cultivated for their attractive flowers, foliage, shapes and other reason such as shades. It is often forgotten that human beings and land animals are dependent upon plants. They are the essential parts of the ecosystems. Plant uses the light energy captured from the sun to convertĀ carbon dioxide and water into carbohydrates, releasing oxygen as a waste product. This process which is known as photosynthesis, is vital to maintaining normal levels of oxygen and carbon dioxide in the Earth atmosphere. Photosynthesis is the source of energy for nearly all life form on earth, either directly or indirectly.

The first method of classification of plants in this website are based on growth form. Plants are classified as trees if they have woody stems, or trunks, and are generally higher than 2.4 meters (8 feet) when mature. Shrubs here refers to lower height woody and herbaceous plants. Climbers display a growth form based on long stems and often require a physical support to grow.

Another classification method available in this website is by the plantsĀ taxonomy.
