Answer:
Euglenoids lack a Cell wall
Explanation:
Euglena is a unicellular photosynthetic protista that can be found in both salt water and fresh water. As Euglena has chloroplasts they can produce their own food through photosynthesis. For their movement in water they have specialized structure called flagella. Near Flagella another pigmented spot exist called eyespot. Eyespot helps euglena to detect sunlight. Euglenoids lack cell wall so they have more flexibility for movement.
