Marram Grass Adaptations

These flashcards cover key terms and concepts related to the adaptations of Marram Grass for surviving in dry conditions.

Marram Grass

A xerophyte adapted to dry, windy sand dunes.

Xerophyte

A plant adapted to survive in an environment with limited water availability.

Humidity Microclimate

A localized atmosphere that has higher humidity levels due to trapped moisture.

Sunken Stomata

Stomata located in pits or grooves on a leaf surface to protect from air movement.

Water Potential Gradient

The difference in water potential between regions, which drives water movement.

Thick Waxy Cuticle

A waterproof layer on the leaf surface that prevents water evaporation.

Reduced Leaf Surface Area

Having a smaller leaf area to minimize exposure to the atmosphere.

Stomatal Closure

The process of closing stomata during extreme water stress to conserve moisture.

Turgidity-Retaining Cells

Cells that help maintain stiffness in plant tissues, contributing to structural support.

Transpiration

The process of water movement through a plant and its evaporation from aerial parts.
