The desmosomes are concerned with

Correct answer: B. Cell adherence

  • A. Cell division
  • B. Cell adherence
  • C. Cytolysis
  • D. Cellular excretion

Explanation

In desmosomes, circular patches of cell membranes are held together by interaction of proteins that extend through each membrane into the space between cells. The cell membrane has a dense plate of proteins for mechanical support on the inner side and bears fine filaments, the tonofibrils, radiating into the cell. The desmosomes act as "spot welds" and keep the cells firmly together.
