• A. Performing cementing to keep neighbouring cells together
• B. Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules
• C. Separates two cells from each other
• D. Stop substance from leaking across a tissue

Answer 1

The correct option is B Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules

A. Desmosomes perform cementing to keep the neighbouring cells together. It serve anchoring function.

B. Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells for rapid transfer of ions, small molecules and sometimes big molecules,

C. No such junction is present.

D. Tight junctions help to stop substances from leaking across the tissue.

So, the correct answer is 'Facilitate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules'.
