a dwarf alberta spruce is neither it is a needle
Spruce pines, Pinus glabra, have acicular leaves which are needle like.
Conifers are trees such as Pine and Spruce, with long and needle-like leaves.They keep their green leaves year round.
the function of long needle thread will direct in the long needle.
Norway spruce trees (Picea abies) have needles that are arranged in a spiral formation along the branches, which are classified as pinnate. The needles are typically flat and sharp, measuring about 1 to 2 inches long. Unlike palmate or parallel arrangements seen in some other plants, the needle arrangement of Norway spruce is distinctly different, emphasizing its adaptation to its environment.

The cross section of the spruce leaf or needle is square in shape. The pine is flat. The spruce needle is attached singly to the branch on a short peg called a sterigma. Pine needles grow in clusters of two to six, depending on the species. See the related link for more information.
Spruce is a softwood and is recognized by it's excurrent form, (a single, tall, straight trunk with small lateral branches) Other names: Norway Spruce-(European whitewood, European spruce, and whitewood) Sitka spruce-(Silver spruce) Blue spruce. Heights can from 100 FT to 300 Ft depending on variety, it is straight-grained with even texture and is non-durable. Answer evergreen Answer conifer
Both Black spruce and White spruce are coniferous trees. They belong to the Pinaceae family and are characterized by their needle-like leaves and cone-bearing reproductive structures. These trees are typically found in northern regions and are well adapted to cold climates.
Spruce trees are more likely to survive in areas with extreme changes in climate because, spruce trees are equipped with a thick cuticle that covers their needle-like leaves. this waxy cuticle that covers each needle prevents water loss from spruce and pine needles. because of this they are able to survive in cold months, and drastic weather changes, because they do not have to worry about water loss, like other trees. if you have ever noticed, in the winter maple trees have no leaves on them because they are not protected for winter months, while spruce and fir trees needles are still on the tree and look fresh, and not harmed, because they cannot lose water, keeping them healthy all year long.
No, a spruce tree is not a monocot; it is a gymnosperm and belongs to the group of dicots. Monocots and dicots are classifications of flowering plants based on characteristics such as seed structure, leaf venation, and root systems. Spruce trees, which are conifers, produce cones instead of flowers and have needle-like leaves.
Spruce trees belong to the phylum Coniferophyta, which is part of the larger division of gymnosperms. This phylum includes various tree species that produce cones and have needle-like leaves, adapting them to various climates. Spruce trees are specifically classified under the genus Picea within this phylum.
