Which of the following is not a component of a prokaryotic cell? Ribosome Plasma membrane Nucleus Cytoplasm

Break Down the Problem

1. Identify the components of a prokaryotic cell.
2. Determine which option does not belong to prokaryotic cells.

Relevant Concepts

• Prokaryotic cells are defined as cells without a true nucleus and generally have a simpler structure than eukaryotic cells. Key components include:
  • Ribosomes: Involved in protein synthesis.
  • Plasma membrane: A lipid bilayer that controls the entry and exit of substances.
  • Cytoplasm: The gel-like substance inside the cell where metabolic processes occur.
  • Nucleus: A membrane-bound structure that contains genetic material, found in eukaryotic cells.

Analysis and Detail

1. Ribosome: Present in prokaryotic cells, performing essential protein synthesis.
2. Plasma membrane: Standard in all cells, acting as a barrier and medium for communication.
3. Cytoplasm: Found within prokaryotic cells to host cellular processes.
4. Nucleus: Absent in prokaryotic cells; they have nucleoid regions where DNA is located, but no membrane-bound nucleus.

Verify and Summarize

The components of a prokaryotic cell include ribosomes, plasma membrane, and cytoplasm. The only component listed that is not part of a prokaryotic cell is the nucleus.

Final Answer

Nucleus is not a component of a prokaryotic cell.
