Chlorosis means lack of chlorophyll. Specific symptoms are identified with the name. For example, iron chlorosis is a condition due to a lack of iron. Iron chlorosis causes a leaf to become yellow while the veins of the leaf remain green. The newest leaves on ends of branches are the most affected by this condition, although in severe cases all the plants leaves are affected. In advanced stages, iron chlorosis causes plant tissue to die, manifested as brown scorched areas of the leaf.
