Final Answer:
The order of cell structures from A(1) to E(5) is as follows:
1. Nucleus (5)
2. Nucleolus (4)
3. Rough endoplasmic reticulum (3)
4. Golgi apparatus (1)
5. Mitochondrion (2)
Step-by-step explanation:
The nucleus (5) is the control center of the cell, housing genetic material. The nucleolus (4) is a region within the nucleus responsible for ribosome synthesis.
The rough endoplasmic reticulum (3) is involved in protein synthesis and transport. The Golgi apparatus (1) processes and packages proteins for export. Lastly, the mitochondrion (2) is the powerhouse of the cell, producing energy through cellular respiration.
The correct order is crucial for understanding the flow of cellular functions. Starting with the nucleus (5) as the central hub of genetic information, the nucleolus (4) contributes to ribosomal formation.
The rough endoplasmic reticulum (3) is where proteins are synthesized, followed by the Golgi apparatus (1), which processes and packages proteins. Finally, the mitochondrion (2) generates energy. This sequence aligns with the cellular hierarchy, emphasizing the significance of each structure in maintaining cellular functions.
