• The Cell

Eukaryotic (with membrane bound nucleus)
Prokarotic (without membrane bound nucleus)

A Typical Animal Cell

• Nucleus
• Nucleolus
• Mitochondria
• Endoplasmic Reticulum
• Golgi Apparatus
• Peroxisomes
• Lysosomes

• Chloroplast
• Amyloplast
• Vacuole
• Plasmodesmata
• Centrioles

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

8
Lactobacillus

• Rod shaped
• In yogurt
• Lives on lactose (milk sugar)

9
Oscillatoria

• Identifying Characteristics
• Long, green filaments
• Chloroplasts arranged along periphery

10
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

11
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

12
Paramecium

• Identifying Characteristics
• Slipper shaped
• Food gullet
• Macronucleus micronucleus
• Anterior posterior contractile vacuole
• Cilia
