Question

Quizplus · Accepted Answer

The number of chromosomes in diploid eukaryotic cells can vary considerably between different species, ranging from just 2 in some species of roundworms to over 1000 in some species of ferns. Therefore, option D is the only correct answer. Options A and B are incorrect as the number of chromosomes is not always 46 and cannot be predicted by the size of the organism. Option C is also incorrect as the number of chromosomes does not change with growth and aging, it remains constant throughout the life of an organism.
