Guida verificata passo dopo passo1
Understand the difference between prokaryotic and eukaryotic cells. Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not.
Recall that animal cells and plant cells are types of eukaryotic cells, meaning they contain a nucleus enclosed by a membrane.
Recognize that prokaryotic cells, such as bacteria, lack a membrane-bound nucleus; their genetic material is not enclosed within a nuclear membrane.
Identify that the question asks for the type of cell without a membrane-bound nucleus, which points to prokaryotic cells.
Conclude that the correct answer is 'Prokaryotic cell' because it is the only cell type listed that lacks a membrane-bound nucleus.
