This biome features a thick, closed canopy which blocks light to the floor and allows little underbrush. As a result, the ground is often covered with fungi ...
The conifers, division Pinophyta, are one of 13 or 14 division level taxa within the Kingdom Plantae. They are cone -bearing seed plants with vascular tissue; all extant conifers are woody plants , the great majority being trees with just a few being shrubs .
The main purpose of the trunk is to raise the leaves above the ground, enabling the tree to overtop other plants and outcompete them for light. [61] It also transports water and nutrients from the roots to the aerial parts of the tree, and distributes the food produced by the leaves to all other parts, including the roots. [62]

The Cupressaceae trees contain a wide range of extractives, especially terpenes and terpenoids, [39] both of which have strong and often pleasant odors. The heartwood, bark and leaves are the tree parts richest in terpenes. [40] Some of these compounds are widely distributed in other trees as well, and some are typical for Cupressaceae family.
