Solution

(a) No, there is no relationship between the size of an organism and its chromosome number.

(b) No, the process of reproduction follows a common pattern and is not dependent on the number of chromosomes.

(c) Yes, since the major component of a chromosome is DNA, if there are more chromosomes in a cell, the quantity of DNA will also be more.
