Classes of Plants Two classes : Angiosperms and gymnosperms Angiosperm = flowering plants Gymnosperms = non flowering plants (usually involves reproduction through seeds)
Monocot vs. Dicot Angiosperms (flowering plants) are divided into monocots and dicots As the zygote grows into the embryo, the first leaves of the young plant develop and are called cotyledons (seed leaves) Monocots have one cotyledon (corn, lily, etc). Dicots have two cotyledons (bean, oak, etc).
Monocot vs. Dicot Number of cotyledons: one vs. two
Monocot vs. Dicot Leaf venation pattern: Monocot is parallel Dicot is net pattern
Monocot vs. Dicot root Monocot: Dicot: Fibrous root Tap root
Monocot vs. Dicot Flower parts: Monocot: Dicot: in groups of three in groups of four or five
Monocot vs. Dicot Vascular bundle position: Monocot: scattered throughout the stem Dicot: arranged in a circle
Monocot vs. Dicot Stem types: Monocot: Dicot: Herbaceous herbaceous or woody
