Organelles can be separated from cell homogenate through:

Correct answer: C. Differential centrifugation

  • A. Chromatography
  • B. X-ray diffraction
  • C. Differential centrifugation
  • D. Auto-radiography

Explanation

The correct answer is differential centrifugation because it utilizes differences in size and density to isolate organelles from a cell homogenate. The process involves centrifuging the homogenate at progressively higher speeds to selectively sediment different organelles. Chromatography, X-ray diffraction, and auto-radiography are not suitable for this purpose: chromatography separates chemical mixtures, X-ray diffraction examines atomic structures, and auto-radiography detects radioactive materials.
