🌵 A cactus is a type of plant that typically grows in dry and arid regions. It is characterized by its thick, fleshy stems, which are covered in spines or thorns. Cacti have adapted to survive in harsh desert conditions by storing water in their stems and having specialized features like shallow roots and waxy coatings to reduce water loss. These unique plants come in various shapes and sizes, with some cacti even producing vibrant flowers. They are known for their resilience and ability to thrive in environments where other plants struggle to survive.
