There are different varieties of plants with spines, some have spines on their leaves while others have spines made of modified leaf stipules.
Leaves that have spines are not capable of photosynthesis and at maturity these leaves’ spines become dead.
Some plants have been converted into spines as in the case of cacti.
Spinose structures are hard and rigid extensions of either leaves, stems, roots, or buds with sharp, stiff ends and their general function is simply to deter animals from eating the plant material.
1. Cactus Plants with Spines
The Cactus plants are slow-growing but they are self-sufficient as it stores moisture in leaves, roots, and stems.
They are succulent perennial plants and they generally have thick herbaceous or a woody chlorophyll-containing stem.
They are native through most of the length of North and South America.
Cacti are distinguishable from other succulent plants either by spines or barbed bristles.
In most cases, the cactus plants are absent leaves or they are modified as spines, minimizing the amount of surface area from which water can be lost.
The tropical genera Pereskia and pereskopsis have vines that have conventional-looking functional leaves.
Over time cactus leaves evolved into spiky spines that help plants in surviving hot, dry environments.
The spines also act as a defense mechanism to discover herbivores from eating the plants, they also serve as shades for the plants from the sun.

Plants having vines have more access to reach sunlight without expending much of their energy.
There are different plants with different varieties of vines located in different places on the plant body with some on the leaves while others on modified leaf stipules.
Some plants having vines are not even capable of photosynthesis and at maturity, some of these leaves vines die off.
