What are the primary functions of the central vacuole in plant cells?

• A. Protein synthesis and modification
• B. Photosynthesis and energy production
• C. DNA replication and repair
• D. Storage of nutrients and waste products

Answer: (D)

Verified step by step guidance

1. Understand that the central vacuole is a large, membrane-bound organelle found in plant cells.
2. Recognize that one of the primary functions of the central vacuole is to store nutrients and waste products. This helps maintain the cell's internal environment.
3. The central vacuole also plays a role in maintaining turgor pressure, which is the pressure of the cell contents against the cell wall. This is crucial for maintaining the plant's structural integrity.
4. Another function of the central vacuole is to store pigments and secondary metabolites, which can contribute to the plant's coloration and defense mechanisms.
5. Finally, the central vacuole can help in the breakdown of complex molecules, acting similarly to lysosomes in animal cells, by containing enzymes that degrade macromolecules.
