There are many different kinds of plants on our planet which can be divided into three main types: herbaceous, woody and climbing plants. Among them, more than 300,000 species have been found and recorded. Plants play an important role to other living things as plants can produce their own food and release oxygen through the process of photosynthesis. Apart from breathing the oxygen, other living things have to obtain energy by eating plants or other organisms that eat plants for survival. Besides, plants are also homes of many living creatures. For humans, plants provide raw and processed materials as well for their use, such as timbers, firewood, oils, rubbers, fibers, dyes, medicine, etc. Connect to the MMIS to find out more.
