Plants are essential for life on earth; they are the backbone of all life. Plants are considered as autotrophic organisms, seeing as they are able to produce their own food. 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 …show more content…
There are two ways this process can be carried out; anaerobic or aerobic. Plants normally aerobically respite but in case of little to no exposure to air, anaerobic respiration is done. The process of cellular respiration takes place in the mitochondria of cells.

All functions and structures in plants have been adapted to optimise the processes of photosynthesis and respiration. Plants have a root system, a stem, branches and leaves. The roots primary job is to absorb water and the nutrients from the soil. This is done with the help of the extra surface area that the root hairs provide (Gillaspy, 2008). Once water and minerals have diffused into the roots and root hairs, there are two types of tissue that helps transport the minerals and water through the stem to the leaves; xylem and
