Directives for Naming Organisms
• The first name is always the Genus name
• The second name is always the species name
• The first letter of the first name is always in upper case &
the first letter of the species name is always in the lower
case
• The name is written in italics or alternatively underlined
• e.g. Amoeba proteus OR Amoeba proteus
Lactobacillus
• Rod shaped
• In yogurt
• Lives on lactose (milk sugar)
Oscillatoria
Identifying Characteristics
• Long, green filaments
• Chloroplasts arranged along periphery
Gloeocapsa
Identifying Characteristics
• Loosely arranged colony of cells
• Usually about 6-12 cells in one bundle
• Cells are green and round
• Colony covered by gelatinous sheath
Amoeba
Identifying Characteristics
• Irregular shape
• Pseudopodia (false feet): cytoplasmic extensions
that aid in locomotion & phagocytosis (cell eating)
• Note: Contractile vacuole is NOT an identifying
characteristic peculiar to Amoeba
Paramecium
Identifying Characteristics
• Slipper shaped
• Food gullet
• Macronucleus & micronucleus
• Anterior & posterior contractile vacuole
• Cilia
