Final answer:
The number of chromosomes in a monoploid cell can be found by dividing the total number of chromosomes by 4. In this case, there would be 15 chromosomes in a monoploid cell.
Step-by-step explanation:
The plant has a total of 60 chromosomes, represented by 4n. In this case, 'n' represents the number of chromosomes in a monoploid (haploid) cell. To find the number of chromosomes in a monoploid cell, we divide the total number of chromosomes by 4. So, 60/4 = 15 chromosomes would be found in a monoploid cell.
