WebThere are approximately two to six thylakoids that join within the chloroplast. The pyrenoid can be thought of as a small compartment inside of the chloroplasts that is unique to algae. Eyespot: Located at the anterior end of the Chlamydomonas, the eyespot (also known as the stigma) is uniquely colored orange. It is photoreceptive and helps ... When feeding as a heterotroph, Euglena takes in nutrients by osmotrophy, and can survive without light on a diet of organic matter, such as beef extract, peptone, acetate, ethanol or carbohydrates. When there is sufficient sunlight for it to feed by phototrophy, it uses chloroplasts containing the pigments chlorophyll a and chlorophyll b to produce sugars by photosynthesis.
