Which of the following statements is TRUE?
A)Integrins and cadherins facilitate cell adhesion to extracellular substrates.
B)Cadherins on the surface of animal cells permit cells to adhere to other cells.
C)Cadherins are used in plant cells to attach the plasma membrane to the cell wall.
D)Integrins on one cell attach to cadherins on another cell to promote cell adhesion.

Question

Quizplus · Accepted Answer

Cadherins on the surface of animal cells are responsible for cell-cell adhesion, allowing cells to adhere to other cells. Integrins, on the other hand, facilitate cell adhesion to extracellular substrates such as the extracellular matrix. Cadherins are not used in plant cells, as they have a different mechanism of cell-cell adhesion involving plasmodesmata. Integrins and cadherins do not directly interact with each other to promote cell adhesion.
