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.
The needles are the leaves of the tree, which allow it to carry out photosynthesis and produce food
Pine needles are typically grouped in clusters known as "fascicles." The number of needles in each fascicle can vary among different species of pine, commonly ranging from two to five needles per bundle. This grouping helps the tree conserve water and withstand environmental conditions.
The longleaf pine (Pinus palustris) is native to the southeastern United States and is known for having the longest pine needles, which can grow up to 18 inches in length. These long needles help the tree conserve water in the hot and dry climates where it typically grows.
Pine needles have a thick, waxy coating that helps them retain water and resist drying out during winter. This allows them to stay green and attached to the tree throughout the colder months. Additionally, pine trees are adapted to conserve energy by keeping their needles, which are expensive to produce, rather than shedding them during winter.
Christmas trees, typically pine or fir trees, smell like pine due to the presence of volatile organic compounds called terpenes in their needles. Terpenes release a strong scent when the tree is cut, contributing to the familiar pine fragrance associated with Christmas trees.

Pine trees shed their needles gradually throughout the year, with older needles turning yellow and falling off while new ones grow in their place. This process helps the tree conserve energy and adapt to changing seasons.
Roots
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.
pine needles in Tagalog: no direct translation but it is referred to as pine tree also in Tagalog. Example is the Baguio pine tree.

Too much water can turn white pine needles brown. This is especially true in areas with poor drainage conditions and lots of rain.
