The lengths of meristematic (l ₘ) and fully-elongated cells (l ₑ) were measured in the roots of 118 monocot and dicot species of herbaceous plants from 20 angiosperm families. The results were analyzed using the data on haploid DNA content (C ᵥₐₗ) for the same species from the website (http://data.kew.org/cvalues). The distribution range of l ₘ, l ₑ, and C ᵥₐₗ was wider in monocot plants compared to dicots. Values of l ₘ and l ₑ in monocot and l ₘ in dicot species correlated positively with C ᵥₐₗ. Dependence of l ₘ and l ₑ on C ᵥₐₗ was similar in diploid and polyploid species, both monocots and dicots. The average length of root cells differed less than the root length.
