Grass
Explanation
Venation refers to the arrangement of veins and veinlets in the lamina of a leaf. It is a primary morphological characteristic used to distinguish between the two major groups of angiosperms: Monocotyledons (Monocots) and Dicotyledons (Dicots).
Analysis of Venation Types:
- Parallel Venation: In this type, the veins run parallel to each other within the lamina. This is the characteristic feature of Monocotyledonous plants. Common examples include Grass, Wheat, Maize, and Banana.
- Reticulate Venation: In this type, the veins and veinlets form an intricate network or web. This is the characteristic feature of Dicotyledonous plants. Examples include Rose, China Rose (Hibiscus), and Mustard.
Conclusion:
Among the given options, Grass is the only monocot and therefore exhibits parallel venation. Rose, China Rose, and Mustard are dicots and exhibit reticulate venation.
Key Takeaway:
Monocots typically possess leaves with parallel venation, whereas Dicots typically possess leaves with reticulate venation.
