The ability to adapt to environment was a key factor in early  land plant survival, as well as their spread into less-hospitable areas. We explore and highlight some of these factors, and illustrate these, using examples of some simple and complex ways in which plants have successfully adapted to their environments. Adaptations usually appear as a result of a number of pressures chief of these pressures is the environment which the plant occupies. A good example of adaptation to environment can be see in Conophylum minuium shown to the right, a member of the Aizoaceae  that has highly reduced fleshy leaves, exposing a minimum surface area to the environment, thereby minimizing water loss.
