An individual could develop exogenous depression after losing a loved one or experiencing some other type of traumatic event. Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems. 1 2 Namely, they are endogenous and exogenous antigens.

The slow growing roots were all inhibited by exogenous IAA and ABA at any concentrations used whereas for the fast growing roots their elongation was promoted by these two hormones at low concentrations. Treatment for endogenous infection. S2D). Send us feedback. create disparities in the earth's surface, while exogenous forces (waves, glaciers, wind, etc.) However, poor understanding of the rates and controls of root life span has hindered the prediction of carbon (C) flow and nutrient cycling dynamics at the ecosystem scale.2.
