Organelles can be separated from cell homogenate through:
Correct answer: C. Differential centrifugation
- A. Chromatography
- B. X-rays diffraction
- C. Differential centrifugation
- D. Auto-radiography
Explanation
Differential centrifugation is a widely used method for separating organelles from a cell homogenate. It takes advantage of the differences in size, shape, and density of the cellular components. During the process, the cell homogenate is subjected to a series of centrifugation steps at different speeds, allowing the larger and denser organelles to pellet at lower speeds while smaller components and debris remain in the supernatant.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
