Q4

A researcher is studying different types of cells. In which cell type will he/she encounter the highest number of lysosomes ?

  1. (a) Pancreatic cell
  2. (b) Ovarian cell
  3. (c) Muscle cell in the thigh of a runner
  4. (d) White blood cellCorrect answer

Solution.

Answer: (d) White blood cell

  1. Phagocytic white blood cells, especially neutrophils and macrophages, digest engulfed microbes using lysosomal enzymes.
  2. Their defensive role makes white blood cells the best choice; high energy demand in muscle instead points to abundant mitochondria.
