Question

Which organelles might be needed in greater numbers than the generalized cell for a white blood cell, skeletal muscle cell, and pancreatic cell, respectively?

A. White blood cell: Nucleus (for DNA replication); Skeletal muscle cell: Mitochondria (for energy production); Pancreatic cell: Endoplasmic reticulum (for protein synthesis)

B. White blood cell: Mitochondria (for energy production); Skeletal muscle cell: Ribosomes (for protein synthesis); Pancreatic cell: Golgi apparatus (for processing and packaging)

C. White blood cell: Lysosomes (for digestion); Skeletal muscle cell: Nucleus (for DNA replication); Pancreatic cell: Endoplasmic reticulum (for protein synthesis)

D. White blood cell: Golgi apparatus (for processing and packaging); Skeletal muscle cell: Mitochondria (for energy production); Pancreatic cell: Ribosomes (for protein synthesis)

Answer 1

Option C is correct because white blood cells require lysosomes for the digestion of pathogens, skeletal muscle cells need mitochondria for energy production, and pancreatic cells use the endoplasmic reticulum for protein synthesis.

Step-by-step explanation:

The organelles that would be needed in greater numbers for a white blood cell, skeletal muscle cell, and pancreatic cell, respectively, are:

• White blood cell: Lysosomes (for digestion of invading pathogens)
• Skeletal muscle cell: Mitochondria (for ATP production needed for muscle contraction)
• Pancreatic cell: Endoplasmic reticulum (especially the rough ER for its role in protein synthesis for enzyme production)

Option C is the correct answer: White blood cell: Lysosomes (for digestion); Skeletal muscle cell: Mitochondria (for energy production); Pancreatic cell: Endoplasmic reticulum (for protein synthesis).
