Adapting to terrestrial living - Essay ExampleAdaptations to tackle this problem include zoology like skeletons and specialized lay cells and tissues which support the plant. A transition from aquatic to terrestrial life also meant a competitive struggle for sunlight as a result plants had to be tall, which also necessitated sloshed stems and an extensive root system to anchor the plants firmly in the ground while they grew upwards towards the sunlight (www.countrysideinfo.co.uk) and this is turn led to the development of trees.Another requirement for air based living as distant to aquatic life is the need to conserve peeing, beca role a plant may face constraints in obtaining an commensurate supply of water from the soil. As a result, they have developed a cuticle or tutelar layer on the surface of leaves to prevent excessive loss of water by transpiration (www.countrysideinfo.co.uk). At the said(prenominal) time however, plants must also be able to absorb carbon dioxide fr om the atmosphere to carry on the process of photosynthesis and give out carbon dioxide. This objective had to be achieved without sacrificing the modes for preservation of water through the use of the cuticle.The adaptations made in plants to specifically cater to this requirement are stomata on the underside of the leaf, which allow the vary of gases to take emplacement without excessive loss of water from the surface of the leaf. For example, in drought prone areas, plant leaves are reduced to spines, so that the leaf surface from which loss of water can take place is considerably reduced. Plant species growing in drought ridden areas may demonstrate high levels of stomatal conductance, photosynthesis and photosynthesis during periods when water is available, but enter into periods of dormancy and lose their leaves during a period of intense heat (Lambers et al, 2008)Plants have evolved from unprejudiced unicellular organisms into complex multi cellular ones. A unicellular org anism
