From the internet, gather information about the chromosome numbers of five animals and five plants. Correlate the number with the size of 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.

(a) No, there is no relationship between size of organism and its chromosome number. A smaller organism may have more chromosomes than a larger organism.
(b) No, process of reproduction follows a common pattern and is not dependent on the chromosome number. Ability to reproduce depends on a variety of factors like availibility of nutrients, water, suitable mate, etc.
(c) Yes, since the major component of chromosome is DNA, if there are more chromosomes in a cell, the quantity of DNA will also be more.
