Cacti have three main adaptations that help them in survival. They are water storage, spines, and roots.
● Water storage
Cacti store water in their body to overcome the scarcity of water in an extremely hot climate.
● Spines
Spines are modified leaves that protect the plant from any attack by herbivores. This modification also makes sure that water loss is minimal.
● Roots
The roots of cacti grow deep and hold the plant firmly in the soil. They are modified to collect and store water and food
