Final answer:
A dividing plant cell has entered telophase when nuclear envelopes form around the daughter chromosomes, and cytokinesis typically follows with the formation of a cleavage furrow in animal cells or a cell plate in plant cells.
Step-by-step explanation:
A dividing plant cell has entered telophase when nuclear envelopes form around the daughter chromosomes at each of the poles and nucleoli become visible in specific regions of the daughter nuclei. During this phase, chromosomes that have arrived at each pole begin to decondense, meaning they relax and lengthen after having been tightly coiled during earlier stages of division. The process of cytokinesis then typically follows telophase. In animal cells, cytokinesis is facilitated by the formation of a cleavage furrow that constricts and eventually divides the cell into two. In plant cells, however, a cell plate forms and leads to the development of a new cell wall that separates the daughter cells. The result of cell division in this context is typically four haploid cells if the division is meiotic or two diploid cells if it is mitotic.
