Question

Choose the correct matching of cell organelles with their structure and function:

• A. I, II, III, IV
• B. II, III
• C. II, III, IV
• D. II only

Hint:

Always remember: Mitochondrion is the powerhouse producing ATP, and Chloroplast carries out photosynthesis. Other organelles like Golgi and Nucleolus require careful distinction based on their specific roles in protein processing and rRNA synthesis.

Answer 1

The Correct Option is B

Step 1: Understand the given columns.
Column A lists cell organelles:
I. Golgi bodies
II. Mitochondrion
III. Chloroplast
IV. Nucleolus
Column B lists structural characteristics or descriptions:
- Single membraned, powerhouse of cell, carbohydrate synthesis, ribosomal factory.
Column C lists their functions:
- Protein synthesis, DNA replication, protein synthesis, 80S and 70S ribosomes synthesis.

Step 2: Match organelles with correct structure and function.
- Golgi bodies: single-membrane organelle, involved in processing and packaging proteins, not in carbohydrate synthesis specifically in this context.
- Mitochondrion: double-membraned, powerhouse of the cell, produces ATP. Correct match.
- Chloroplast: double-membraned, site of carbohydrate synthesis (photosynthesis). Correct match.
- Nucleolus: site of ribosomal RNA synthesis and assembly of ribosomal subunits (80S in eukaryotes, 70S in prokaryotes).

Step 3: Eliminate incorrect matches.
- Golgi body does not match perfectly with any function listed in column C.
- Nucleolus does not match precisely with functions given (if 80S/70S ribosome synthesis is listed for cytoplasm; nucleolus is the site of rRNA synthesis).

Step 4: Conclusion.
Only Mitochondrion (II) and Chloroplast (III) correctly match structure and function.
