Question

Is the Euglenoid a single-celled or multicellular organism? Did the Euglenoids you observed change shape? What does that suggest about their surface? What structure provides strength and flexibility to the plasma membrane of Euglenoids? Can you see the structure that propels the Euglenoid? What is it and where is it located? 2. 3. 4. What is the function of the eyespot in Euglenoids? How is this connected to movement of the organism? 5. 6. Many species of Euglenoids are mixotrophs - what does that mean?

Explanation / Answer

1.Euglenoids are mostly single-celled organisms,most of them are autotropic(which prepare their own food)but some are heterotropic(which depend on other organisms for food)2.euglenoids are spindle shaped cell i-e (15-500)micrometers,euglenoids change the shape because they lack rigid cellulose wall instead they have flexible pellicle(surface) 3. the flexibility and contractability of euglenoids are maitained by pellicle sliding over the pelicle strips over one another gives the movement 4.FLAGELLA are whip like struture that propels the euglenoids which is attached to the cell 5.euglena has a red spot called eyespot that helps in finding the sunlight the eyespot is importantb because it helps to move towards light which is source of energy for photosynthesis hence movement of organism 5.mixotroph are the organisms which uses different sources for food ,euglenoids are both autotropic and heterotroipc
