Question

Holozoic nutrition is characteristic of which algae group?

• A. Xanthophyta
• B. Bascillariophyta
• C. Euglenophyta
• D. Cyanophyta

Answer 1

The correct option is C Euglenophyta

Holozoic nutrition refers to engulfment of whole/part of plant/animal in liquid/solid state. Absorption of liquid food through general body surface is referred to as absorptive nutrition. Euglenoids are unicellular flagellated eukaryotes that lack cell wall but have pellicle which is a semi-rigid proteinaceous structure and thus can change their shape. The heterotrophic Euglenoid engulf the particulate food through its pellicle i.e., holozoic nutrition.

Therefore, the correct answer is option C.
