In temperate forests throughout the northern Hemisphere, trees burned their leaves throughout autumn together cold weather approaches. In tropical and also subtropical forests, trees melted their leaves at the onset of the dry season. Many varieties of trees burned their leaves as a strategy to survive harsh weather conditions. Trees the lose every one of their leaves for component of the year are recognized as deciduous trees. Those the don’t are dubbed evergreen trees.

In tropical and also subtropical regions, deciduous trees encompass several types of acacia, baobab, roble, ceiba, chaca and also guanacaste.Image via Tosca Yemoh Zanon in London
Most deciduous tree have vast leaves that space susceptible to being damaged throughout cold or dried weather. In contrast, many evergreen trees either live in warm, wet climates or they have weather-resistant needles for leaves. However, there space exceptions in nature, such together tamarack trees that melted their needles every autumn and live oaks the retain their vast leaves because that the whole year even in fairly cool climates.
Shedding pipeline helps trees to conserve water and also energy. Together unfavorable weather approaches, hormone in the trees trigger the procedure of abscission by which the pipeline are actively cut-off the the tree by specialized cells. The word abscission share the same Latin source word as that in scissors, scindere, which means “to cut.” in ~ the begin of the abscission process, trees reabsorb beneficial nutrients from their leaves and also store lock for later on use in their roots. Chlorophyll, the colours that gives leaves their environment-friendly color, is among the an initial molecules to be damaged down for its nutrients. This is among the reasons why trees rotate red, orange, and also gold colors during the fall. In ~ the finish of the abscission process, as soon as the leaves have actually been shed, a protective class of cell grows end the exposed area.
The shedding the leaves might also help trees to pollinate come springtime. Without pipeline to obtain in the way, wind-blown pollen have the right to travel longer distances and reach more trees.
