In this specimen of onion root cells, what is the amount of time, in minutes, spent in interphase

Approximately it will consume 55% of the total time in the interphase i. e. 800 minutes.

Explanation:

The time required in different phases are as follows:

It takes 800 minutes for interphase

It takes 400 minutes for prophase

It takes 120 minutes for metaphase

It takes 80 minutes for anaphase

It takes 40 minutes for telophase

Total - - 24 hours

From this it can be concluded that around 55% of the time spent in the interphase, whereas only 28% in the prophase, 8% time for metaphase, 6% Anaphase and 3% Telophase. This is all happens in the onion cell but in case of the human cell, prophase it takes about 15 min, in prometaphase it takes 15 mins, metaphase takes in about 20 min, Anaphase takes minimum of 3 min and telophase is about and cytokineses are about less then 10 mins.
