Here are the essential concepts you must grasp in order to answer the question correctly.
Prokaryotic vs. Eukaryotic Cells
Prokaryotic cells are simple, unicellular organisms without a nucleus or membrane-bound organelles, while eukaryotic cells are more complex, containing a nucleus and various organelles. This fundamental distinction is crucial for understanding cellular biology and the organization of life forms.

Cell Wall Composition
The presence or absence of a rigid cell wall is a significant characteristic that can help differentiate between prokaryotic and eukaryotic cells. Many prokaryotes, such as bacteria, have a cell wall made of peptidoglycan, while most eukaryotic cells, like plant cells, have a cellulose-based wall, and animal cells lack a cell wall entirely.

Internal Membranes and Ribosomes
The presence of internal membranes is a key feature of eukaryotic cells, which compartmentalize cellular functions, while prokaryotic cells lack such structures. Ribosomes, present in both cell types, are essential for protein synthesis, but their size and location can provide clues about the cell type, with eukaryotic ribosomes being larger and found in the cytoplasm or attached to the endoplasmic reticulum.
