angiosperms

Plant Non-Vascular Ph.Hepatophyta Marchantia Vascular Seedless plants Ph. polypodiophyta fern seed plants Gymnosperms Ph . Pinophyta Pinus Angiosperms Ph. Magnoliophyta Monocot Zea maize Dicot Capsella

angiosperms Known as flowering plants Produce reproductive structures called flowers and fruits Produce seeds that are enclosed in ovaries (fruit) Includes phylum Magnoliophyta

Characteristics of Monocots . one cotyledon leaves have parallel veins . e.g. zea maize

Characteristics of Dicot . Seeds with two cotyledons . leaves have veins in network . e.g. Capsella
