Multiple Choice
Which statement best describes the presence of a cell membrane in cells?
A
All cells have a cell (plasma) membrane.
B
Only animal cells have a cell membrane; plant cells do not.
C
Only eukaryotic cells have a cell membrane; prokaryotic cells do not.
D
Cells with a cell wall do not have a cell membrane.
Verified step by step guidance1
Step 1: Understand the role of the cell membrane. The cell membrane, also known as the plasma membrane, is a fundamental structure that surrounds the cell, controlling the movement of substances in and out of the cell.
Step 2: Recall that all cells, whether prokaryotic or eukaryotic, have a cell membrane. This membrane is essential for maintaining the internal environment of the cell.
Step 3: Recognize that plant cells and some other cells have an additional outer layer called the cell wall, but this does not replace the cell membrane; rather, the cell membrane lies just beneath the cell wall.
Step 4: Eliminate incorrect statements: animal cells are not the only cells with a membrane, prokaryotic cells also have membranes, and cells with cell walls still have cell membranes.
Step 5: Conclude that the best description is that all cells have a cell (plasma) membrane.
