Verified step by step guidance
1
Identify the key structural differences between prokaryotic and eukaryotic cells. Prokaryotic cells are generally simpler and lack membrane-bound organelles, while eukaryotic cells have complex structures with membrane-bound organelles.
Understand that the presence or absence of a nucleus is a fundamental distinction. Prokaryotic cells do not have a nucleus; their genetic material is located in a nucleoid region. Eukaryotic cells have a defined nucleus that houses their genetic material.
Evaluate the statement about cell size. Typically, prokaryotic cells are smaller than eukaryotic cells, not larger.
Consider the presence of mitochondria. Eukaryotic cells contain mitochondria, which are the powerhouses of the cell, whereas prokaryotic cells do not have mitochondria.
Examine the statement about cell walls. While many prokaryotic cells have a cell wall, some eukaryotic cells, such as plant cells, also have a cell wall. Therefore, this is not a distinguishing feature between all prokaryotic and eukaryotic cells.
