Animals that are not able to adapt migrate in the winter. With Xylem cells die quickly. These directions are determined by a transducing system that converts physical signals into physiological signals that control the morphological and anatomical development of the roots. These trees tend to be more skinny as they are trying to gain any sunlight they can. The tropical rain forest is a forest with tall trees in a region of year round high temperatures where an average of 50 to 260 inches of rain falls yearly.
