Plants have many adaptations to cope with the lack of water. Some desert plants, such as the barrel cactus, have expandable stems for storing water. Other plants have adaptations that reduce water loss from their leaves, the part of a plant through which most of the water is lost. Still others have a waxy coating on the leaves, or have small leaves, that reduce the surface area exposed to the drying elements. In many cases, desert plants have no leaves at all.
What is angiogenesis? Angiogenesis is the formation of new blood vessels. This process involves the migration, growth, and differentiation of endothelial cells, which line the inside wall of blood vessels. The process of angiogenesis is controlled by chemical signals in the body. These signals can stimulate both the repair of damaged blood vessels and the formation of new blood vessels. Other chemical signals, called angiogenesis inhibitors, interfere with blood vessel formation.
