Based on the data in the table, the most accurate inference is Cells spend most of their time in interphase because cells need time to grow, copy their DNA, and prepare for division.
Here's the rationale:
The majority of cells (61%) are in the interphase, which includes the stages of growth (G1), DNA synthesis (S), and preparation for mitosis (G2).
The percentages for prophase, metaphase, anaphase, telophase, and cytokinesis are much lower, indicating that these stages are relatively shorter in duration compared to interphase.
This aligns with the general understanding that cells spend a significant portion of their life cycle in interphase, where they carry out various activities such as growth and DNA replication before undergoing cell division.
The other options are not well-supported by the data:
The data doesn't indicate that cells spend most of their time in mitosis (second option). In fact, the mitotic stages (prophase, metaphase, anaphase, telophase, and cytokinesis) collectively make up a smaller percentage compared to interphase.
There's no clear indication in the data that supports the idea of more cells undergoing prophase than telophase due to the breakdown of the nuclear envelope and condensation of genetic information. The percentages for prophase and telophase are relatively low, and the difference between them is not substantial.
