Why are adhering junctions common in tissues subject to constant abrasion or stretching, such as skin?
A) These cells need to communicate by allowing cytoplasm to flow between adjacent cells.
B) The cells in these tissues require strong cell-to-cell junctions to hold them together.
C) Adhering junctions prevent harsh enzymes from flowing between adjacent cells.
D) These tissues do not have basement membranes.
E) Adhering junctions allow production of a protective cuticle.

Quizplus · Accepted Answer

Adhering junctions provide strong mechanical attachments between adjacent cells through cytoplasmic filaments and transmembrane proteins. This structural support is crucial in tissues like skin that undergo constant physical stress, ensuring the cells remain intact and connected despite abrasion or stretching.
