Pneumatophores:

  • Halophytes are plants that grow in marshy or swampy areas.
  • There is a severe shortage of oxygen in swampy soils.
  • Therefore, in the plants growing in these areas, for example, Rhizophora, the roots come out of the soil and grow vertically upwards.
  • These roots, which are negatively geotropic and positively phototropic are called pneumatophores. 
  • The pneumatophores have numerous pores that allow the diffusion of oxygen.
  • These pores are called lenticels.
  • These roots are non-photosynthetic.

 

                                          

Pneumatophores are the modified tap roots found in the plants growing in marshy areas. These are negatively geotropic as they grow above the soil. These are non-green and bear numerous pores called lenticels that allow for gaseous exchange.
