Study Notes

Bacteria Structure Key Components

Pili: Short projections on the bacterial surface, crucial for adherence to other bacterial cells and surfaces.
Flagella: Long, tail-like structures that enable motility by propelling the bacteria through liquid environments.
DNA (Nucleoid): Contains deoxyribonucleic acid, serving as the genetic blueprint that determines cell structure and function.
Cell Membrane: A semi-permeable barrier that separates the cell's interior (cytoplasm) from the external environment (cell wall).
Capsule: A gelatinous outer layer, also known as the "slime layer," that provides protection and enhances adherence to surfaces.
Plasmids: Small, circular DNA fragments that often carry genes for traits such as antibiotic resistance, found predominantly in bacteria and some eukaryotes.
Cell Wall: A rigid structure surrounding the cell membrane, offering additional protection and structural support to the bacterial cell.
Cytoplasm: The gel-like substance filling the interior of a cell, comprising cytosol and organelles, each performing vital functions for cellular processes.
