Correct answer: B. Organelles on the basis of their density

  • A. Bacteria on the basis of Gram staining
  • B. Organelles on the basis of their density
  • C. Bological molecules on the basis of their polarity
  • D. Chlorophyll pigments on the basis of their ability to absorb light

Explanation

Centrifugation is a technique that separates components of a mixture based on their density and size by spinning them at high speed. When centrifuged, denser organelles like nuclei will settle at the bottom, while less dense components remain higher up in the tube. Option B is correct because it accurately describes this separation process. Options A, C, and D describe processes or properties (Gram staining, polarity, and light absorption) that do not involve centrifugation.

About Cytoplasmic Organelles

Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
