Summary Introduction
To explain: The reason for which euglenozoa cannot be classified either as plants or animals.
Introduction: The unicellular protists diplomonads, parabasalids, and euglenozoans are grouped as Excavata. This is based on the DNA sequence and cytoskeletal similarities, thereby showing evolutionary relatedness.
