They can be broad or needle-like, simple or compound, lobed or entire, smooth or hairy, delicate or tough, deciduous or evergreen. The needles of coniferous trees are compact but are structurally similar to those of broad-leaved trees. They are adapted for life in environments where resources are low or water is scarce. Frozen ground may limit water availability and conifers are often found in colder places at higher altitudes and higher latitudes than broad leaved trees. In conifers such as fir trees, the branches hang down at an angle to the trunk, enabling them to shed snow. In contrast, broad leaved trees in temperate regions deal with winter weather by shedding their leaves. When the days get shorter and the temperature begins to decrease, the leaves no longer make new <a href="/wiki/Chlorophyll" title="Chlorophyll">chlorophyll</a> and the red and yellow pigments already present in the blades become apparent.<sup id="cite_ref-Pessarakli_76-1" class="reference"><a href="#cite_note-Pessarakli-76"><span class="cite-bracket">[</span>76<span class="cite-bracket">]</span></a></sup> Synthesis in the leaf of a <a href="/wiki/Plant_hormone" title="Plant hormone">plant hormone</a> called <a href="/wiki/Auxin" title="Auxin">auxin</a> also ceases.
