Protozoan Fine Structure and Functional Microanatomyhysiological functions not found in other groups. Some taxonomic distinctions are based on the presence of these characteristic organelles. For example, the Kinetoplastida are characterized, among other features, by the presence of a mitochondrial-like body possessing a large mass of DNA called a ki

The protozoa comprise a vast ensemble of organisms with wide diversity in morphology and environmental adaptations. One of the major unifying principles, however, amidst this di

David M. Harland,Ralph D. Lorenzilia are clustered at sites on the surface of the cell, either as somewhat loosely arranged tufts or organized into cirri (Figure 6.2c). A cirrus is a composite group of cilia (few to hundreds of cilia), often tapering toward the distal end and acting in unison. They typically are found in localized
