Sakayama et al., (2005) y Sakayama (2008) describen con MEB la morfologia interna de la POC fracturada en varias especies del genero Nitella identificando tres patrones morfologicos: el homogeneo, el debilmente esponjoso y el fuertemente esponjoso.

Nitella is a form of what fisherman call 'carpet grass,"' says Jim Sweatman, Fish Orlando Coordinator, Freshwater Fisheries Management Division (NE Region), FWC.
Sin embargo hay que notar que las especies indicadoras adicionales Myriophyllum quitense y
Nitella flexilis tambien se pueden presentar en pequenos riachuelos con escasas a fuertes corrientes de agua.
Some freshwater algae - namely,
Nitella and Navicula pelliculosa (diatom) - also produce arachidonic acid (Hitchcock & Nichols, 1971).
(AEP, Espana, Chara,
Nitella, Tolypella, Charophyceae, Veget, Bioin).
In a long living cell of green algae,
Nitella or Chara, the thin layer of the endoplasm is observable streaming very fast at a peed of ~50 [micro]m/s just beneath the cell wall by light microscopy.
Likewise, in order to understand the complex behaviors of whole plants, some plant physiologists have turned to the giant algal cells, such as Chara and
Nitella, where vegetative and reproductive growth and development, adaptive physiological mechanisms, and nutrient uptake and translocation can be readily studied (Amino & Tazawa, 1989; Andjus & Vucelic, 1990; Barber, 1911a, 1911b; Beilby et al., 1993; Bisson & Bartholomew, 1984; Bisson et al., 1991; Blatt & Kuo, 1976; M.
The most frequent genera in each life form included the following: emergent -- Hymenachne, Urochloa and Eleocharis; rooted submerged -- Chara,
Nitella, Egeria and Hydrilla; free floating -- Eichhornia and Salvinia; amphibious -- Panicum; floating leaved -- Nymphoides and Nymphaea; free submerged -- Utricularia; epiphyte -- Oxycaryum.
Otras plantas de menor importancia que existen en el Lago San Pablo son: Elodea matthewsii, Hydrocotyle ranunculoides, Lemna minor, Azolla caroliniana, Potamogeton pusillus y
Nitella flexilis.
