Bacterial Colonies

Bacterial colonies are visible groups of bacteria that grow on surfaces like agar plates or other substrates. Each colony originates from a single bacterial cell that divides and multiplies, forming a cluster. They can vary in size, shape, color, and texture, which helps scientists identify different bacterial species. The appearance of colonies provides important clues about bacterial growth patterns and characteristics. In essence, bacterial colonies are the visible evidence of microbial growth, allowing for study, identification, and understanding of bacteria in various environments.
