The given statements are some charaters of a particular group of Kingdom protista
(i) Most of them are frest water organisms found in standing water.
(ii) They have a protein rich layer (called pellicle ) which makes their body flexible.
(iii) They have two flagella, a short and a long one.
(iv) Though they are photosynthetic in the presence of sunlight, but in the absence of sunlight they behave like heterotrophs by preadating on other smaller organisms.
Identify the correct group on the basis of these charaters.
Text Solution
Verified by ExpertsD
The characteristics listed in the question perfectly describe the group Euglenoids, particularly the genus Euglena:
Habitat: They are primarily freshwater organisms found in stagnant (standing) water.
Flexible Body: They lack a rigid cell wall and instead have a protein-rich outer layer called a pellicle, which provides flexibility for movement and shape changes.
Flagella: They typically possess two flagella: one long and one short.
Mixotrophic Nutrition: They exhibit a dual mode of nutrition—photosynthetic in sunlight (using pigments identical to higher plants) and heterotrophic (predatory) when sunlight is unavailable.
