Final answer:
True, most cells grow to a certain size, halt growth, and then divide. The cellular growth process is highly regulated, usually halting when conditions are suboptimal or when cells have differentiated to perform specific functions, unlike cancer cells which can exhibit uncontrolled growth and division.
Step-by-step explanation:
True. Most cells do reach a certain size, stop growing, and then divide. This process is tightly regulated and occurs during the cell cycle. When cells experience unfavorable conditions, they may enter a state known as G0 phase, where they stop dividing and remain dormant until conditions improve. Cells go through stages of growth, such as G1 and G2, where they synthesize materials needed for cell division, but these phases do not necessarily involve an increase in cell size. Terminally differentiated cells permanently exit the cell cycle in the G0 phase and do not divide further. In contrast, cancer cells often lack the control mechanisms that regulate cell division and can grow and divide uncontrollably.
