Answer:
Correct Answer: B
Solution:
The number of dicot species is over 200,000.
About 50,000 species of monocots are known.
Dicots are characterised by the presence of two cotyledons in the seed, generally reticulate venation in leaves, concentric tissues in the stem with open vascular bundles arranged in a ring, penta or tetramerous flowers.
Where as monocots have single cotyledon, parallel venation scattered closed vascular bundles.
