Which of the following are functions of the prokaryotic cell wall?

• A. Facilitates the process of photosynthesis
• B. Provides structural support and shape to the cell
• C. Stores genetic information
• D. Regulates the movement of substances in and out of the nucleus

Answer: (B)

Verified step by step guidance

1. Understand the structure of a prokaryotic cell: Prokaryotic cells, such as bacteria, lack a nucleus and membrane-bound organelles. They have a cell wall, plasma membrane, cytoplasm, and genetic material.
2. Identify the composition of the prokaryotic cell wall: The cell wall in prokaryotes is primarily composed of peptidoglycan, a polymer that provides rigidity and strength.
3. Determine the primary function of the cell wall: The main role of the prokaryotic cell wall is to provide structural support and maintain the shape of the cell, protecting it from osmotic pressure and mechanical damage.
4. Evaluate the options given: Consider each option in the context of the cell wall's known functions. The cell wall does not facilitate photosynthesis, store genetic information, or regulate substances in and out of the nucleus (as prokaryotes do not have a nucleus).
5. Conclude with the correct function: Based on the analysis, the correct function of the prokaryotic cell wall is to provide structural support and shape to the cell.
