Species of plants possesses characteristics that allow it to survive in certain conditions. This is why the distributions of plants vary from one area to another. Each species must be able to successfully capture these resources and use them to acquire energy and biomass for growth and reproduction.

One of the factors that affect the distribution of plants is temperature. Most species of plant live in moderate temperature zones (around 35°C) is due to the fact that the enzymes, biological catalyst which speed up reaction in plant cells work at the best rate in an optimum temperature. As temperature increases the more energy enzymes have to move around and speed up reaction but
