The function of the cell membrane is to control the movement of substances in and out of the cell.
The correct answer is "control the movement of substances in and out of the cell."
To arrive at this answer, we can eliminate the other options by understanding the function of the cell membrane. Here's how you can reason this out:
1. Control the movement of substances in and out of the cell: The cell membrane is responsible for regulating the transport of molecules and ions into and out of the cell. It allows certain substances to enter or exit the cell while preventing others from doing so. This selective permeability is crucial for maintaining the internal environment of the cell.
2. Generate energy: Energy generation in a cell primarily occurs in the mitochondria, not the cell membrane. The cell membrane's role is more focused on controlling transport rather than energy production.
3. Synthesize proteins: Protein synthesis occurs in the ribosomes and endoplasmic reticulum, not the cell membrane. Though the cell membrane plays a role in the transportation of proteins, its primary function is not protein synthesis.
4. Store genetic information: Genetic information is stored in the nucleus of eukaryotic cells or within the nucleoid region in prokaryotic cells. The cell membrane does not directly store genetic information.
Therefore, based on this reasoning, we can conclude that the correct function of the cell membrane is to control the movement of substances in and out of the cell.
