Do pine trees get water through roots or needles?
Roots
Why do trees have needle like leaves?
Deciduous trees are trees that lose their leaves. Trees that don't lose their leaves are "Evergreens". Evergreen trees have needles, instead of flat leaves, to survive winter hardship. Needles cut evaporation so trees can save water - dear in the winter. Not all trees that bear needles are evergreen, for example the larch drops it's needles in the Autumn.
How are needles an advantage to trees in the boreal forest?
Fir, spruce, hemlock, and other coniferous trees all have thick, waxy needles that prevent water from evaporating
Why do conifers have leaves like needle?

Why do you water Christmas trees when they are already dead?
== == If you don't water them, they will get dried out and drop needles.
What is the primary role of the needles of a scrub pine tree?
The "needles" on a pine tree or other conifer are the plant's leaves, where photosynthesis takes place. The needles are long and slender because of the environment of the trees. Needles lose less water and heat than typical leaves.
Waxy watertight outer covering that prevents the above-ground parts of a plant from losing water to the air?
cuticle
How pine needles help pine tree conserve water?
Trees lose water through transpiration (the passing of water vapor to the atmosphere). Pine needles are waxy, have a small surface area and have a groove in which the stomata are located. These features reduce transpiration.
Why do needles float on water?
Needles float on water because needles are less dense than water. This is partially because the water is so much larger of a substance than the needles.
Waxy watertight outer covering that prevents the above ground parts of a plant from losing water?
the cuticle prevents dessication
Describe the leaves of trees that in the taiga?
The taiga, or boreal forest, is given to high seasonality with a long season during which temperatures are below the freezing point of water. As such, trees must be conifers, with very limited leaves (needles) adapted to the cold, or be deciduous trees that are well adapted to the stress involved in losing its leaves every year. For instance, I live in the central region of Alaska. We have deciduous trees and conifers. The farther north you go though, the fewer deciduous trees there are.
How do conifer trees survive?
They adapt to their climate by having needles that stay all year round. These hold in water. They also have more chloroplast. Because the needles stay all year round, photosynthesis can occur more quickly, as soon as the water melts.
