Protozoa
• Unicellular • @150μm• No cell walls• Trophozoite and cyst
forms• Classified by means of
locomotion• Examples:
– Paramecium– Amoeba

Bacteria
• Unicellular• @ 1-5μm in length• Cell wall• 3 shapes:– Cocci– Bacilli– Spirillum

Algae
• Most unicellular• Photosynthetic• Examples:– Green algae – 5-10 μm– Volvox – 500 μm
