Which are recycling centers for the cell?

• A. Ribosome and Golgi apparatus.
• 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 each organelle mentioned in the options. Ribosomes are involved in protein synthesis, and the Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
2. Consider the role of the endoplasmic reticulum and chloroplast. The endoplasmic reticulum is involved in the synthesis of proteins and lipids, while chloroplasts are responsible for photosynthesis in plant cells.
3. Evaluate the function of mitochondria and the nucleus. Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration, and the nucleus houses the cell's genetic material and controls cellular activities.
4. Focus on the central vacuole and lysosome. The central vacuole in plant cells stores nutrients and waste products, while lysosomes contain enzymes that break down waste materials and cellular debris, making them key recycling centers.
5. Conclude that the central vacuole and lysosome are the correct answer as they are primarily involved in recycling and waste processing within the cell.
