{'cell organelles': [0, 1, 2, 7], 'ribosomes': [1, 0, 0, 0], 'endoplasmic reticulum': [2, 0, 0, 2], 'mitochondria': [2, 0, 1, 2], 'golgi body': [1, 0, 1, 1], 'lysosome': [3, 0, 3, 7], 'own dna': [0, 0, 0, 1], 'plastids': [2, 0, 1, 4]}

Option 1: Golgi body and Endoplasmic Reticulum

The Golgi body and endoplasmic reticulum are both involved in the processing, modification, and transport of proteins, lipids, and other molecules in the cell. However, they do not possess their own DNA and ribosomes. Ribosomes are involved in protein synthesis and are found either bound to the endoplasmic reticulum or free in the cytoplasm. Therefore, option 1 is incorrect.

Option 3: Lysosome and Golgi body

Lysosomes are responsible for breaking down waste materials and cellular debris. While they contain some enzymes, they do not have their own DNA and ribosomes. As explained earlier, the Golgi body is involved in protein modification and transport but does not have its own DNA and ribosomes. Hence, option 3 is also incorrect.

Option 4: Vacuole and Plastids

Vacuoles are responsible for storing water, nutrients, and waste products in plant cells. They do not have their own DNA and ribosomes. Plastids, such as chloroplasts, are involved in photosynthesis, but they do possess their own DNA and ribosomes. However, this option is incorrect as vac
