What characteristics are common in bacterial cells?

Bacterial cells exhibit specific characteristics that distinguish them from eukaryotic cells. They typically possess a cell wall, which provides structural support and protection. The plasma membrane, located beneath the cell wall, regulates the movement of substances in and out of the cell, ensuring a controlled internal environment.

One of the defining features of bacterial cells is the absence of a true nucleus; instead, their genetic material is located in a nucleoid region, which is not membrane-bound. Additionally, bacterial cells generally lack membrane-bound organelles, such as mitochondria or the endoplasmic reticulum, which are found in eukaryotic cells. Instead, bacterial functions often occur in the cytoplasm or at the membrane.

These traits highlight the simplicity of prokaryotic cells, like bacteria, in comparison to more complex eukaryotic cells that contain organized organelles and a distinct nucleus. Finding the absence of a nucleus and organelles is key to identifying bacterial cells correctly.
