Want this question answered?
Conifers are trees such as Pine and Spruce, with long and needle-like leaves.They keep their green leaves year round.
The leaves of pine trees are needle-like.
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.
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.
Pine and spruce trees
Broadleaf.
Examples of needleleaf trees include pine, spruce, fir, and cedar. Needleleaf trees are characterized by their long, thin leaves in the shape of needles, which remain on the tree year-round. They are typically coniferous trees and are common in colder climates.
Conifers.
A conifer has needle shaped leaves. The cones are the seed bearers.
Forests dominated by trees with needle like leaves are Coniferous.
i do not know
Pine trees will always have needle shaped leaves, they stay like this forever. The "needle shaped leaves" are called pine needles. Most pine trees belong to a group of trees called Evergreens. Like it's name, the tree is evergreen.
