Correlate the number with the size of the organism and answer the following questions.(a) Do larger organisms have more number of chromosomes/cells? (b) Can organism with fewer chromosomes reproduce more easily than organisms with more number of chromosomes? (c) More the number of chromosomes/cells greater is the DNA content. Justify.

1. The number of chromosomes has nothing to do with the size of the organism.

2. In comparison to creatures with more chromosomes, organisms with fewer chromosomes do not need to reproduce as quickly.

3. DNA makes up chromosomes. As a result, having more chromosomes means having more DNA.
