Cell Junctions and Cell Signalling Pathways · Zoology

Desmosomes mainly provide which function to tissues?

  1. Chemical signaling between adjacent cells
  2. Electrical coupling for rapid communication
  3. Strong mechanical adhesion
  4. Selective transport across the membrane
Show answer and explanation

Correct answer: Strong mechanical adhesion

Desmosomes anchor cells together by linking intermediate filaments. This provides mechanical strength, especially in tissues exposed to stress like skin.
