in the life cycle of a
flowering plant
(angiosperms)
Seed types
• Monocot seeds and Dicot seeds
• Example of a monocot seed is a corn seed
• Example of a Dicot seed is an apple seed

Parts of a monocot seed
Corn seed

Roots of Angiosperms
Dicots have one long
thick root called a
taproot with
secondary small roots
growing from it.
Monocot Roots
The monocot root is made up of small
branching fibers
Stems
• Stems contain tubes with veins that carry food
down to the plant’s roots and water and minerals
upward to the leaves.
The bundles of veins within a
monocot stem are scattered.
The bundle of veins of a
dicot stem are arranged in
a neat circle
Leaves
• Leaves of a Monocot plant have parallel veins
• Leaves of a Dicot plant have intersecting veins
that form a branching pattern.
