Question

in the human body, when a tissue becomes damaged it usually is replaced with scar tissue. the liver is a unique organ because it is able to regenerate tissue if it becomes damaged. which principle from the cell theory supports this finding? sc.912.l.14.1
a. cells are created by free - cell formation.
c. existing cells are produced by other living cells.
d. cells communicate with each other and produce special chemical messengers to repair tissue.
b. cells generate more cells during cell division.

Explanation:

Cell theory states that all cells come from pre - existing cells. When the liver regenerates damaged tissue, new cells are formed from existing liver cells. Option A is incorrect as free - cell formation is not a valid part of modern cell theory. Option D is not a principle of cell theory. Option B is a bit too general as cell division is a process but the key principle is that new cells come from existing ones (Option C).

Answer:

C. Existing cells are produced by other living cells.
