Natural selection was probably the culprit, but what event/animal caused it to evolve into a plant with splkes for defense, I do not know.
As in sewing needles or pinhead needles - no. But they're long, narrow and really pointy, which make them very much like needles.
The Pointy Bit and the eye of the needle...
Neem leaves are in a long cocoon sort of shape with a few pointy edges.
Corn leaves are long, narrow, and blade-shaped. They typically have a length of 2-5 feet and can grow up to 1 foot wide. The leaves are arranged alternately along the stem and have a prominent midrib running through the center.
calls-Last answer BS Diamond when shined and cut is smooth and pointy at the edges, when it is not yet refined it is like a regular rock, rough and stuff.
yes needles are pointy.

they are pointy and green...like a pine needle?
Pointy objects such as needles??
It has pine needles! (They are in groups of 5. They are green and pointy.) :)
Short and pointy leaves are a common adaptation in cold climates. The Pine tree is well known for these kinds of leaves. The short pointy shapes of the leaves allows snow to easily fall off them when it's snowing. The leaves are also coated in special enzymes that reduces the effect of the cold especially from snow that managed to trap itself on the leaves.
yes they did back in the day the algonquians did use fish bones to make sewing needles because they were so sharp and pointy
Some animals have special rough mouths that protect them from the hard pointy needles of the cactus. Like, a collared pecary
quills the pointy part is called quill a quill is also a feather pen

Softwood tree leaves are typically needle-like or scale-like in structure. They are usually narrow, with a pointed tip, and can be either clustered together in bundles (as in pine trees) or attached individually to the branch. Softwood trees, such as pines, firs, and spruces, tend to have leaves that are evergreen and stay on the tree year-round.
