CLADOPHORA

GENERAL CHARATERSTICS OF CLADOPHORA​

  • Cell walls are stratified being composed of three layers, out of which middle is conspicuously stratified. 
  • A cell is coenocytic. Central region is occupied by a large vacuole, surrounded by outer cytoplasmic lining in which many nuclei are present.
  • Chloroplast is either reticulate or discoid. It is parietal in position and possesses many pyrenoids.
  • The Cladophora species can be a major nuisance causing major alteration to benthic conditions linked particularly with increased phosphorus loading.
  • There are two multicellular stages in its life cycle – a haploid gametophyte and a diploid sporophyte.
  • Cladophora balls are formed from the filaments of the alga which are photosynthetic.
  • Cladophora is cosmopolitan and accordingly infestations cannot often be regarded logically as being invasive. Where they occur they may at various times be seen as beneficial, as a nuisance, or an outright pest.
