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

توضیح

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.
