A xerophyte is a plant which has adapted to life in dry climates - where little water uptake is possible.

Plant Adaptations[edit | edit source]

Root Adaptations[edit | edit source]

Roots are extensive and shallow because the periodic, short and light rains do not penetrate the ground with more than a few inches of water.

Roots are dense and hairy to increase surface area.

Leaf Adaptations[edit | edit source]

  • In cacti, leaves have become spines. This reduces the surface area of the leaves and therefore reduces water loss from the plant.

Stomata Adaptations[edit | edit source]

  • Some plants only have their stomata open at night; and some have fewer stomata. These both reduce water loss by evaporation and transpiration.

Stomata are often sunken and surrounded with hairs that trap water vapor. This decreases transpiration.

Stem Adaptations[edit | edit source]
