Why do artichokes have pointy needles in the leaves of their exterior?
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.
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.

If you want, use hot glue to glue a bead to the end or put clay on the end. These work great! (trust me, i used them for like three months before i got real needles)

The pine apple grows close to the ground in the center of a plant that is made up of thin rigid long pointy leaves that are up to about 800 mm long. They all point outwards and upwards from the center of the plant. the pineapple or pine apples grow from near the centre over where the leaves emanate from the plant.
But they do... cacti leaves look like thorns to us. The reason their leaves evolved into thorns is to reduce water loss. Answer They do have leaves, but they don't look 'normal'. Their leaves are the needle-like things sticking out of the stem, and they attach themselves to your skin to draw blood. The reason their leaves are not like 'normal' ones, is because of the heath cacti are exposed too. Large leaves are not…
