They are a crucial resource for many different uses, as plants are primary producers; everything we eat comes directly or indirectly from them (Schaffner, 2010). They provide a whole range of useful products, including food, fibres for cloth, and energy sources. Wood, coal and natural gas are all sourced from plants, these fuels are used on a daily bases by millions of people. Basically all medicine has various types of plant traces in them. Plants are also the primary habitat for millions of animals. Animals live on, in or under them (Missouri Botanical Garden, 2009). They create shelter, shade, protection and safety. Furthermore, plants control the global CO2 and O2 levels. Oxygen is produced as a by-product of the process of photosynthesis; this allows the survival of all living organisms. Finally, plants use carbon dioxide in the process of photosynthesis or store large amounts of carbon, which both significantly help reduce air pollution and therefore lowers global warming effects (BGCI, 2014). Hence humans and other animals rely directly on plants for survival.

The primary source of energy for nearly all life on earth is the sun. The energy from sunlight is converted into chemical energy through a process known as photosynthesis. This process only occurs in plants, algae and some types of…
