• In cactus, the leaves are modified into spines which are needle-like structures. These spines help in the prevention of water loss and provides protection against the predators.
• Stems in cactus are thick and fleshy which helps in storing the water. It contains the green colour pigment called chlorophyll which traps sunlight to perform photosynthesis.
