Question

On a field trip, students collect a few samples to analyze back in their classroom. One student picks a blade of grass in the field and identifies it as a dicot leaf, but his partner thinks it is a monocot. Which explanation supports his partner’s opinion?

a) Presence of reticulate venation
b) Parallel venation
c) Presence of pinnate venation
d) Lack of venation

Answer 1

Monocot leaves have parallel venation, while dicot leaves have reticulate venation.

Step-by-step explanation:

The partner is correct in saying that the leaf is a monocot because monocots have leaves with parallel venation. Dicot leaves, on the other hand, have reticulate venation. Parallel venation means that the veins of the leaf run in straight lines across the length of the leaf without converging at a point. In contrast, reticulate venation forms a net-like appearance, with veins that branch out and connect with each other.
