Final answer:
Prokaryotic cells have a cell wall that provides protection against osmotic pressure, while eukaryotic cells have complex organelles that enable multicellular organisms to perform complex and specialized tasks. Eukaryotic organelles facilitate compartmentalization which is essential for multicellular organization, tissue differentiation, and complex life forms.
Step-by-step explanation:
Two key differences between prokaryotic and eukaryotic cells are structure and complexity. Prokaryotic cells do indeed have a cell wall that provides structural support, aiding in protection against osmotic pressure. However, this is not primarily for locomotion. On the other hand, eukaryotic cells possess complex organelles that allow for specialized functions through compartmentalization.
Eukaryotic cells, with their various organelles, enable multicellular organisms to perform more complex and specialized tasks. For instance, the presence of a nucleus with a double membrane in eukaryotic cells protects and regulates access to DNA, something that prokaryotes lack. Additionally, the eukaryotic organelles, such as mitochondria and chloroplasts, capture and transfer energy through cellular respiration and photosynthesis, respectively, which are essential processes for multicellular life. The structural complexity of eukaryotic cells supports multicellular organization, tissue differentiation, and ultimately, complex life forms.
