Question

Quizplus · Accepted Answer

Tissue growth occurs through cell division, so increasing the rate of cell division is the most likely way a tissue will increase in size.

 While tissues may also increase in size by recruiting cells from surrounding tissues or by increasing blood supply, increasing the size of its current cells is another potential means of growth. By increasing the size of its cells, the tissue is able to increase in size without having to devote as much energy to cell division.
