What are prickly leaves?
Spines are modified leaves, stipules, or parts of leaves, such as extensions of leaf veins. Some authors prefer not to distinguish spines from thorns because, like thorns, and unlike prickles, they commonly contain vascular tissue.

Why do leaves have different characteristics?
However, some leaves may have different colors, caused by other plant pigments that mask the green chlorophyll. The thickness, shape, and size of leaves are adapted to the environment. Each variation helps a plant species maximize its chances of survival in a particular habitat.
What are needle like leaves an adaptation?
The needle-like leaves are an important adaptation to Conifer trees because they do not accumulate much snow, keeping the weight load mild. The waxy cuticle on the epidermis is an extremely important adaptation because it protects the photosynthetic cells that are below in the mesophyll.
