Final answer:
True. A cell's fate is determined during differentiation.
Step-by-step explanation:
True
During the process of differentiation, a cell becomes more specialized and takes on specific characteristics and functions. This is when a cell's fate is determined, as it becomes committed to a certain pathway of development. Differentiation is influenced by factors such as gene expression and activation of specific transcription factors. Therefore, the statement that a cell's fate is determined during differentiation is true.
