In which terrestrial biome can you find trees that produce cones instead of flowers and needles instead of leaves?

Taiga biome

Taiga biome is a terrestrial biome, which exhibit short hot summers and long cold winters. This biome is found in regions of North America, Russia , Canada and Eurasia. This biome receives moderate precipitation. The trees in these regions have specific adaptation to conserve water and nutrition. This biome is characterized by coniferous trees, which produces cones and exhibit needles instead of leaves. The wooden barks of these trees is also hard. During winter season, plants does not receive adequate water and sunlight. Therefore, in order to prevent transpiration and photosynthesis. The needles replaced leaves and cones replaced flowers.

Boreal or Coniferous forest

Explanation:

Plants that bear their seeds on cones and possesses needle-like leaves are known as conifers (a group of gymnosperms). They include pines, spruces and firs etc.

Boreal/Coniferous/Taiga forest is found in countries like Canada, Russia, and Northern Europe etc. It has a cold, dry winter and short, cool and wet summer. The long and cold winters in the Boreal forest have led to the predominance of evergreen cone-bearing plants who are better adapted to the cold climates known as Coniferous trees. Their needles are adaptive features to their habitat in the sense that, it helps them absolutely heat from sunlight, hence making them begin photosynthesis as soon as temperature rise above freezing (early spring). The needles also help them prevent water loss during transpiration because the stomata are located at the underside of the needles coated with a waxy cuticle.

Hence, the name of their biome, Coniferous forest.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
