Describe the adaptations that enable plants to survive on land.

There are a number of adaptations that allow plants to survive on land. A prominent adaptation is the vascular system. This consists of xylem and phloem tissues that transport nutrients and water to various parts of the plants. This extensive transport system allows the plants to gain height and become large in size. The plants have also adapted to reduce the water loss across cell walls. This is made possible by waxy cuticles. Another adaptation is the stomata that can open and close and allow the exchange of gases (generated during photosynthesis and respiration) and water vapors. Stomata are present on the leaf surfaces. Seed dispersal is another adaptation and allows the plant to propagate. Without dispersal there are chances that daughter plants may be infected by the same/similar predator or infection as the parent plant.


Hope this helps.
