السؤال 18

Which observations could correctly describe ribosomes in a generalized animal cell? Select all that apply.

  1. Tiny particles floating freely in the cytoplasmالإجابة الصحيحة
  2. Large membrane sacs filled with cell sap
  3. Tiny particles attached to rough endoplasmic reticulumالإجابة الصحيحة
  4. Protein filaments forming an internal framework

الشرح

Tiny particles free in cytoplasm and tiny particles attached to rough endoplasmic reticulum can both be ribosomes. A large membrane sac is the wrong structural class because ribosomes are small and have no surrounding membrane. Protein filaments form the cytoskeleton's internal framework, whereas ribosomes are discrete ribonucleoprotein particles.
