Characteristics of Bacterial Cells

In the study of microbiology, understanding the structure and function of bacterial cells is critical in dissecting their role in ecosystems and health. Bacteria are unicellular organisms that replicate asexually through binary fission. They have distinct structural components, including a cell membrane, cytoplasm, ribosomes, and in some cases, a rigid cell wall made of peptidoglycan. The diversity of bacterial forms can be classified into shapes such as cocci (spherical), bacilli (rod-like), and spirilla (spiral).
