Which statement about net-veined leaves is true?

• A. Grass leaves have net-veined leaves
• B. Broadleaf weeds have net-veined leaves
• C. Grass-like plants have net-veined leaves
• D. Netted-veined leaves do not apply to weeds

Answer: (B)

Leaf venation patterns separate plant groups. Net-veined leaves have a branching network of veins (reticulate venation), which is common in broadleaf plants and many weeds that are dicots. In contrast, grass and grass-like plants show parallel venation, with veins running side by side from base to tip and little cross-connecting network.

So, broadleaf weeds having net-veined leaves is the true statement because they are typically dicots with this venation pattern. The other options don’t fit: grasses and grass-like plants do not have netted veins, and the idea that net-veined leaves don’t apply to weeds ignores the many broadleaf weeds that do have this leaf structure.
