Understand the question: The problem is asking for a feature that is shared by all cells, regardless of whether they are prokaryotic or eukaryotic. This requires knowledge of the basic structures and functions common to all cells.
Review the options: Analyze each option to determine if it applies universally to all cells. For example, a cell wall is present in plant cells and some prokaryotes but not in animal cells, so it is not a universal feature.
Recall the universal features of cells: All cells, whether prokaryotic or eukaryotic, share certain characteristics. One of these is the presence of a plasma membrane, which acts as a selective barrier regulating the entry and exit of substances.
Eliminate incorrect options: Chloroplasts are specific to plant cells and some protists, and a nucleus is only found in eukaryotic cells. These features are not shared by all cells.
Conclude the correct answer: The plasma membrane is the feature shared by all cells, as it is essential for maintaining the integrity and functionality of the cell.
