Question 5
A prokaryotic cell contains A. a nucleus. B. a vacuole. C. ribosomes. D. endoplasmic reticulum.
Worked Solution & Example Answer:A prokaryotic cell contains A - VCE - SSCE Biology - Question 5 - 2005 - Paper 1
Step 1
Identifying the Correct Answer
Answer
The correct answer is C. ribosomes.
Explanation
Ribosomes are essential components of all cells, including prokaryotic cells. They are responsible for protein synthesis. In contrast:
- A. a nucleus: Prokaryotic cells do not have a nucleus; instead, their genetic material is located in the nucleoid region.
- B. a vacuole: While some prokaryotic organisms may have similar structures, vacuoles are not typically considered essential components of prokaryotic cells.
- D. endoplasmic reticulum: This organelle is characteristic of eukaryotic cells, not prokaryotic cells.
Thus, ribosomes are the only option that is definitively present in prokaryotic cells.
