How is a cactus adapted to live in desert environments?

A cactus is adapted to survive in desert environments through special features that help it store water and reduce water loss. These adaptations allow cactus plants to grow in areas with high temperatures and very little rainfall.

The thick and fleshy stem of a cactus stores water that can be used during dry periods. Its leaves are modified into spines, which reduce water loss and also protect the plant from animals. A waxy outer covering further helps prevent excessive evaporation.

Cactus plants also have root systems that help them collect available water from the soil. These features make cactus well suited for desert habitats and show how plants develop structures that support survival in different environmental conditions.
