Detailed explanation-1: -So, the correct answer is ‘Metaphase’
Detailed explanation-2: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Detailed explanation-3: -The cell cycle for onion root tips takes about 720 minutes (12 hours).
Detailed explanation-4: -From examination of two images taken under a microscope, approximately 450 cells were tallied. Approximately 60% of the cells were in interphase. The next most common stage observed was prophase, and 35% of cells were in this phase.
Detailed explanation-5: -It takes about 24 hours, or one-thousand, four-hundred and forty minutes, for an onion root-tip cell to complete the cell cycle.
