Lec-2, Structure of Bacterial Cells

Morphology of bacterial cells:
• Shape : it is determined by the bacterial rigid cell wall, the bacteria are classified according to their shapes into four basic groups:
Cocci: are spherical shape.
Bacilli : are rods shape.
Spirochetes : are spiral–shaped.
Pleomorphic: appear in many shapes.
• Size: the size of bacteria ranged from 0.2-5 micrometer (?m).
• Arrangement of bacteria: Certain bacteria are arranged in single cell or in pairs, some in chains, and others in groups.
