Which junction seals cells to stop water leaking between them?

  1. Tight junction
  2. Gap junction
  3. Desmosome
  4. Hemidesmosome
Show answer and solution

Correct answer: A. Tight junction

Tight junctions form a seal that keeps water and solutes from passing between cells.

Which junction links cells strongly via cadherins and intermediate filaments?

  1. Gap junction
  2. Desmosome
  3. Tight junction
  4. Hemidesmosome
Show answer and solution

Correct answer: B. Desmosome

Desmosomes give strong cell to cell attachment by connecting cadherins and intermediate filaments.

Which junction attaches epithelial cells to the extracellular matrix?

  1. Desmosome
  2. Gap junction
  3. Hemidesmosome
  4. Tight junction
Show answer and solution

Correct answer: C. Hemidesmosome

Hemidesmosomes anchor cells to the extracellular matrix using integrins rather than cadherins.
