38.Which one of the features is not observed (examined) to categorise the given plant as monocot or
dicot?
(a) number of cotyledons (b)type of root system (c)colour of petals (d) leaf venation
The answer is C color of petals.
Because monocots have single cotyledon, dicots have two. Monocots have fibrous roots where as dicots have tap roots. Monocots have parallel leaf venation, dicots have reticulate leaf venation. But color of petal can be any thing in both monocots and dicots.
