V. Cells of connective tissue except blood secrete fibers of structural proteins called elastin.

• A. I, II and III only are wrong
• B. I, III and IV only are wrong
• C. III and V only are wrong
• D. I, II and V only are wrong

Answer 1

The correct option is B I, III and IV only are wrong

I. Adhering junctions cement the adjacent cells together. Hence, it is a wrong statement.

II. Areolar tissue contains various cells like fibroblasts, macrophages, adipocytes, mast cells and plasma cells. This statement is true.

III. Gap junctions facilitate the cells to communicate with each other. So, this is a wrong statement.

IV. Tight junctions help to stop substances from leaking across tissues. So, it is a wrong statement.

V. Cells of connective tissue except blood secrete fibres of structural proteins called elastin. It is a true statement.

Hence, the correct option is 'I, III and IV only are wrong'.
