Which amongst the following statement is correct regarding euglenoids?
(a) Majority of them are fresh water organisms found in stagnant water.
(b) They have both plant and animal like characteristics.
(c) They are purely photosynthetic organisms.
(d) They contain chlorophyll a.

Easy
Solution

Though euglenoids are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms. They contain pigment chlorophyll a which resembles plants but they lack cell wall and this property resembles animals. Majority of them are fresh water organisms found in stagnant water.
