If a daughter cell of a plant after mitosis contains 8 chromosomes and 16 pg DNA, then the number of chromosomes and the amount of DNA respectively at the end of S phase is:

After mitosis a cell 2n number of chromosome and 2c amount of DNA. After S phase, the amount of DNA doubles and the number of chromosomes remain the same. Therefore, number of chromosomes =2n= 8 and the amount of DNA is 4c= 16x2= 32pg.
