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.
Verified step by step guidance1
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 storage or transport out of the cell.
Consider the role of the endoplasmic reticulum and chloroplast. The endoplasmic reticulum is involved in protein and lipid synthesis, while chloroplasts are responsible for photosynthesis in plant cells.
Evaluate the functions of mitochondria and the nucleus. Mitochondria are the powerhouses of the cell, generating ATP, and the nucleus houses the cell's DNA and controls its activities.
Identify the role of 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.
Conclude that the central vacuole and lysosome are the correct answer as they are primarily involved in recycling and waste management within the cell.
