Protozoa Cell Diagram. Protective structures protozoa live in potentially dangerous environments and have evolved a variety of protective structures that help them survive. Protozoa is a parasite and in humans they are less than 50 μm in size.
Protozoa are divided into four major groups based on the structure and the part involved in the locomotion. Protozoa are a highly diverse group of eukaryotic unicellular organisms having a wide range of size morphological characteristics and physiological properties. The size of smaller protozoa is from 1 to 10 μm long.
A pellicle the pellicle is a tough flexible layer found outside the cell membrane on all types of ciliated protozoa.
Protozoa are eukaryotic cells. It helps provide the cell with a characteristic shape. This will also help you to draw the structure and diagram of giardia lamblia. In addition most have a tough outer membrane called a pellicle which maintains their form.
