Q. Which of the following characteristics features of Euglenoids:
(a) Have well defined cell wall
(b) Have a protein rich layer called pellicle
(c) Photosynthetic in presence of light, when deprived, behave like heterotrophs
(d) Predating (heterotrophic) on other smaller organism

Biological Classification

Solution:

Majority of them are fresh water organisms found in stagnant water. Instead of a cell wall, they have a protein rich layer called pellicle which makes their body flexible. They have two flagella, a short and a long one. Though they are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms. Interestingly, the pigments of euglenoids are identical to those present in higher plants. Example: Euglena
