Cleavage furrow definition biology quizlet
In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division. The same proteins responsible for muscle contraction, actin and myosin, begin the process of forming the cleavage furrow, creating an actomyosin ring. … WebApr 11, 2024 · Definition. Cleavage furrow refers to an indentation that appears on a cell’s surface when the cell is preparing to divide while a cell plate refers to a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell.
