Label the following: Flagella Gullet Eyespot Chloroplast Nucleus Ø Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Ø Euglena have an eyespot that detects light to help the euglena find bright areas to gather sunlight to make their food. Color the eyespot red. Euglena can also gain nutrients by absorbing them across their cell membrane when light is not available and they cannot photosynthesize. EUGLENA Ø The nucleus contains the cell's DNA and controls the cell's activities. Color the nucleus purple. Ø The contractile vacuole helps the cell remove excess water. Without it the euglena would take in so much water due to osmosis that it would explode. Color the contractile vacuole orange. 1. Are euglena unicellular or multicellular? 2. What Kingdom do euglena belong to?_____________________ 3. What organelle carries out photosynthesis?________________ 4. Describe the two ways in which the euglena get their nutrients. • _______________________________________________ • _______________________________________________ 5. What is the eyespot used for?_________________________ 9. What is the function of the nucleus?_____________________ ____________________________________________________ 10. What is the function of the contractile vacuole? __________________ 11. What would happen if the cell did not have this organelle.___________ ____________________________________________________________ 12. How do Euglena move?________________________________________
