Question

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.

Answer 1

(a) No, there is no relationship between size of organism and its

chromosome number.

(b) No, process of reproduction follows a common pattern and is

not dependent on the number of chromosomes

(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.
