[UP CPMT 2005]


  • Explanation

    Respiratory roots or pneumatophores are found in mangrove plants. Mangroves live in marshy and saline soil, so their roots will not get enough oxygen supply for respiration. Also mangroves suffer from lack of oxygen because these soils are water logged. So mangrove plants produce special aerial branches from the roots. These aerial roots possess minute pores which help in the absorption of oxygen from air. These pores are called pneumatothodes and the roots bearing these pores are called pneumatophores. They are also called as respiratory roots or breathing roots.
