Talk about Euglenoids.

Unicellular/ No cell wall/ most are photosynthetic/ contain chlorophyll a and b and carotenoids in their chloroplast (Euglena)/ Plasma membrane covered by protein bands or strips called pellicle in cytoplasm/ two flagella one for swimming other for light detection along with stigma (eyespot) (reduced) located close to flagelles/ Have contractile vacuole which protects the cell from rupturing because of surrounding water/ energy source in paramylon polysaccharaides/ plastids rich with pyrenoid/ some are heterotrophic others are misotrophic.
