• B. Endoplasmic reticulum and chloroplast.
• C. Mitochondria and nucleus.
• D. Central vacuole and lysosome.
• E. All are correct.

Answer: (D)

Verified step by step guidance

1. Understand the function of recycling centers in a cell: Recycling centers are responsible for breaking down waste materials and cellular debris, and recycling components for reuse within the cell.
2. Identify the role of lysosomes: Lysosomes contain enzymes that digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria, making them key recycling centers.
3. Recognize the function of the central vacuole: In plant cells, the central vacuole stores nutrients and waste products, and can also break down complex molecules, contributing to recycling processes.
4. Evaluate the roles of other organelles: Ribosomes synthesize proteins, the Golgi apparatus modifies and packages proteins, the endoplasmic reticulum is involved in protein and lipid synthesis, chloroplasts conduct photosynthesis, mitochondria generate energy, and the nucleus houses genetic material. These functions do not primarily involve recycling.
5. Conclude that the central vacuole and lysosome are the correct recycling centers based on their roles in waste breakdown and recycling within the cell.
