Most animal cells exhibit anchorage dependence,which means that in order to divide,
A)all chromosomes must be attached to spindle microtubules.
B)nonkinetochore microtubules from opposite poles must overlap and be attached by motor proteins.
C)cell-surface phospholipids must be attached to those of adjoining cells.
D)cells must be attached to a substrate or extracellular matrix of a tissue.

Quizplus · Accepted Answer

Anchorage dependence refers to the requirement of animal cells to be attached to a substrate or extracellular matrix of a tissue in order to divide. This attachment provides signals that regulate the cell cycle, ensuring that the cell divides only when conditions are appropriate. Without this anchorage, cells may undergo uncontrolled division and potentially become cancerous. Therefore, the best choice is D.
