Euglenoids

Basic Information
• Euglenoids or Euglena belong to the phylum
Euglenozoa and are normally found
freshwater areas such as ponds and lakes.
• They are distinguished mainly by the
presence of a pellicle rather then a cell wall
which is composed of proteinaceous strips
underneath the cell membrane, supported by
dorsal and ventral microtubules.
• Currently, over 1,000 species of Euglena
have been discovered with some species that
did didn’t even have chloroplasts.
Movement
• Euglenoids use flagella to propel
themselves through the water.
• Euglenoids also use their light sensitive
stigma or “eyespot” in order to move
toward a light source to photosynthesize.
Nutrition
• In a lighted area, Euglenoids behave as
autotrophs and carryout photosynthesis.
However, if they are in areas with very
low light, they will behave as
heterotrophs and consume small
organisms or bacteria through
phagocytosis.
Reproduction
• Euglenoids reproduce by binary fission.
