When matching organelles with their functions, focus on their primary roles: mitochondria for energy, nucleolus for RNA, Golgi for protein transport, and ER for protein synthesis.
Step 1: Understanding the function of each organelle. Mitochondria: These organelles are known as the "powerhouses" of the cell because they are responsible for energy production in the form of ATP. Hence, the correct function for mitochondria is Energy production (Option III).
Nucleolus: The nucleolus is the site within the nucleus of the cell where ribosomal RNA (rRNA) synthesis takes place. This is the primary role of the nucleolus. Hence, the correct function for the nucleolus is Ribosomal RNA synthesis (Option IV).
Golgi complex: The Golgi complex (or Golgi apparatus) is involved in the processing, modification, and transport of proteins that are synthesized in the rough endoplasmic reticulum. Hence, the correct function for the Golgi complex is Protein processing and transport (Option I).
Endoplasmic reticulum (ER): The endoplasmic reticulum is primarily responsible for protein synthesis. The rough ER, in particular, has ribosomes attached to its surface and is involved in the synthesis of proteins. Hence, the correct function for the endoplasmic reticulum is Protein synthesis (Option II).
Step 2: Match the organelles with their respective functions.
Mitochondria - Energy production (Option III) - A - III
Nucleolus - Ribosomal RNA synthesis (Option IV) - B - IV
Golgi complex - Protein processing and transport (Option I) - C - I
Endoplasmic reticulum - Protein synthesis (Option II) - D - II
Step 3: Conclusion.
The correct matching is:
A - III: Mitochondria - Energy production
B - IV: Nucleolus - Ribosomal RNA synthesis
C - I: Golgi complex - Protein processing and transport
D - II: Endoplasmic reticulum - Protein synthesis
Thus, the correct answer is (4) A - III, B - IV, C - I, D - II.
