Question

A dicot leaf having parallel venation is

• A. Eryngium
• B. Zizyphus
• C. Ricinus
• D. Cassia

Answer 1

The correct option is A

Eryngium

The phenomenon of arrangement of veins on the leaf is called as venation. There are two types venation, namely reticulate venation and parallel venation. Reticulate venation involves irregular distribution of veins to form a network. Examples of plants showing reticulate venation include rose, tulsi, Hibiscus, papaya, Ficus,Bambusa. Parallel venation involves the veins running parallel to each other. Examples of plants showing parallel venation include grains, banana, canna, grass, musa, plum, Zea (maize). Leaves of monocot plants show parallel venation and leaves of dicot plants show reticulated venation. However, there are exceptions in dicots like Corymbium, Calophyllum, Eryngium. They show parallel venation.

Thus, the correct answer is 'Eryngium.'
