Physical Characteristics

One of the most striking features of cacti is their stem structures, which have evolved to store water and minimize water loss. These stems come in various shapes, including cylindrical, spherical, columnar, and branching forms, and are covered in a waxy coating to prevent moisture evaporation. Some cacti also have spines or thorns, which serve to protect the plants from predators and excessive sunlight.

Despite their harsh natural habitats, cacti produce some of the most beautiful and vibrant flowers in the plant kingdom. These flowers come in a wide range of colors, such as red, pink, yellow, and white, and often bloom in response to environmental triggers such as rainfall.
