State three ways in which leaves of marram grass are adapted to survive in dry
weather and explain how each of the features you describe the plant
conserve water.

answer:

marram grass has a rolled leaf that creates a localized environment of water vapour concentration within the leaf, and to prevent water loss. the stomata sit in small pits within the curls of the structure, which make them less likely to open and to lose water.

explanation:

where water is plentiful and temperatures are moderate, plants have wide, thin leaves with lots of surface area for maximum photosynthesis. plants adapted to drought conditions, however, exhibit a number of structural features that prevent water loss, them survive hot, dry conditions. they also have physiological mechanisms that aren't directly observable and that them conserve water. many of these plants are suitable drought-tolerant landscaping subjects.
