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 tissue
1. 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
Epidermis
Vascular
bundles
• Vascular bundles
(xylem & phloem)
are scattered
throughout the
ground tissue.

• Dicot stems have
vascular bundles
arranged in a
ringlike pattern.
