Weed Identification and Morphological Features Quiz

Grasses, sedges, and broadleaf weeds are the three major groups of weeds based on their morphological features.

Grass plants have parallel venation, while broadleaf weeds have netted venation.

Weedy plants are successful because they produce a large number of seeds and their seeds can remain viable for many years.

A plant that completes its life cycle in one year is an annual.

A selective herbicide is more toxic to some groups of plants than others.
