Pines have four types of leaves:
- Seed leaves (cotyledons) on seedlings, borne in a whorl of 4-24.
- Juvenile leaves, which follow immediately on seedlings and young plants, 2-6 cm long, single, green or often blue-green, and arranged spirally on the shoot. These are produced for six months to five years, rarely longer.
- Scale leaves, similar to bud scales, small, brown and non-photosynthetic, and arranged spirally like the juvenile leaves.
- Needles, the adult leaves, which are green (photosynthetic), bundled in clusters (fascicles) of (1-) 2-5 (-6) needles together, each fascicle produced from a small bud on a dwarf shoot in the axil of a scale leaf. These bud scales often remain on the fascicle as a basal sheath. The needles persist for 1.5-40 years, depending on species. If a shoot is damaged (e.g. eaten by an animal), the needle fascicles just below the damage will generate a bud which can then replace the lost leaves.
The leaves of pine trees are called "needles" because of their unique shape: they are very thin and sharp at the tip. The shortleaf pine species is easy to identify.
Pine trees have long, very narrow, evergreen leaves which have a waxy coating and are generally referred to as pine needles.

Do pine trees lose their leaves in winter?
No, pine trees do not have leaves. They have pine needles that have a waxy coat on them. People refer to them as pine leaves sometimes, but that isn't what they are.
Why do pine trees have needle shaped leaves?
because the geographical regions where the pine trees are growing would not allow them to have broad leaves and they have to conserve water also. In addition needle like leaves of the pine trees increase the photosynthetic surface area of these plants.
What are trees that don't shed leaves called?
Evergreens, most of which are conifers or cone bearing trees such as pine.
What are the leaves of a tree called?
The leaves of pine trees are called "needles" because of their unique shape: they are very thin and sharp at the tip. The shortleaf pine species is easy to identify.
Why do pine trees have needle like leaves?

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.
Why trees have needle like leaves?
The leaves of pine trees are needle-like.
What coulor does pine tree leaves turn in autumn?
Pine trees leaves do not change colour during autumn, as they are evergreen trees.
