Which plant type has leaf veins that are netted?

• A. Grass
• B. Horsetails
• C. Herbaceous broadleaves
• D. Biennials

Answer: (C)

Netted (reticulate) leaf veins are a hallmark of dicotyledonous plants, which include many herbaceous broadleaf species. In these leaves the veins form a branching, interconnected network rather than running in parallel. This contrasts with grasses, whose leaves show parallel venation with veins arranged side by side from base to tip, a pattern common in monocots. Horsetails exhibit a simple or forked vein pattern that isn’t a true netted network, and a plant’s growth habit (biennial) doesn’t determine leaf venation. Because herbaceous broadleaves typically display the reticulate venation pattern, they are the plant type described.
