More About Mesophytes

  • Mesophytes are unlike hydrophytes that require plenty water and xerophytes that can survive in dry climate
  • Mesophytes are the terrestrial plants or the land plants that can survive in neither too dry nor too wet conditions
  • The mesophytes have well adapted morphology and physiology to suit the water requirements according to the availability
  • They usually require a continuous supply of water
  • They grow in a moderate climate with regards to the temperature and moisture conditions
  • The stem is rigid and stout
  • The root system is well developed with long tap root in dicots and fibrous rootin monocots
  • They are less tolerant to drought and lose water rapidly
  • The leaves are usually broad, thin, large, dark green in colour and of various shapes. They do not have waxy coating
  • During hot temperatures, they can open the stomata and let the water evaporate to overcome the temperature stress
  • They do not have specific mechanisms as in the xerophytes, , i.e they lack the xeromorphic charteristics
