Monocot vs. Dicot Flowering Plants

IB Assessment Statement

• Outline three differences between Monocotyledons and Dicotyledons

Angiosperms

• Angiosperms are plants that produce flower.

• More than 80% of all plants are angiosperms.

Tow types of Angiosperms

1. Monocotyledons (monocots)

2. Dicotyledons (dicots)

Monocots and Dicots

• All monocots and dicots have vascular tissue.

– Vascular Tissue are tubes that carry food and water to different parts of the plants:

– There are two types of vascular tissue1. Phloem – Tubes that carry food from one part of the

plant to the other

2. Xylem – Tubes that carry water from ROOTS to Leaves

Monocots

• Monocots only have one cotyledon.– A cotyledon is a seedling (baby seed) leaf

Dicots

• Dicotyledon have two cotyledon (baby seed leaves)

Monocot Stems

• Vascular bundles

(xylem & phloem) are scattered throughout the ground tissue.
