Which of the follow is true about prokaryotic cells?
A
They have a plasma membrane, nucleoid, and nucleus
B
They have a plasma membrane, nucleoid, and no nucleus
C
They have a plasma membrane, and reproduce slowly
D
They have a plasma membrane, reproduce slowly, and divide through binary fission
Verified step by step guidance1
Understand the basic structure of prokaryotic cells: Prokaryotic cells are characterized by the absence of a nucleus. Instead, they have a region called the nucleoid where their genetic material is located.
Identify the components of prokaryotic cells: Prokaryotic cells have a plasma membrane that encloses the cell, and they lack membrane-bound organelles such as a nucleus.
Consider the reproduction method of prokaryotic cells: Prokaryotic cells reproduce through a process called binary fission, which is a relatively quick method of cell division.
Evaluate the statements: The statement 'They have a plasma membrane, nucleoid, and no nucleus' correctly describes prokaryotic cells, as they do not have a nucleus but do have a nucleoid.
Eliminate incorrect options: The other statements either incorrectly describe the presence of a nucleus or inaccurately describe the reproduction speed and method of prokaryotic cells.
