63. The morphological feature that allows animal cells to adopt highly variable shapes, migrate throughout tissues, and engulf large foreign particles is the

A. Rigidity of their intermediate filaments
B. Absence of a restrictive, non-living cell wall matrix
✓
C. Presence of dense extracellular cellulose
D. Continuous synthesis of internal turgor

📝 Explanation

Lacking a rigid cell wall allows the animal plasma membrane to stretch, fold, and change shape smoothly, guided by the dynamic cytoskeleton.

📖 Additional Information

  • Rigidity of their intermediate filaments
  • Absence of a restrictive, non-living cell wall matrix
  • Presence of dense extracellular cellulose
  • Continuous synthesis of internal turgor
