blade of grass) - Scattered primary vascular bundles
- Monosulcate pollen (has one indention or dip in
surface) - Flower parts in multiples of three (either have
three of each or have a number that is divisible
by three)
5Characteristics of Monocots
Vascular Bundles Scattered
One Seed Leaf Inside Seed
Parallel Veins on Leaf
Three Petals, Three Leaves

- Dicots are unique flowers. 50 of all dicots
have woody stems among their other unique
features.
7Characteristics of Dicots
- Dicots have
- Two cotyledons (seed leaves)
- Net-veined leaves
- Primary vascular bundles in rings
- Floral parts in multiples of fives
- Tricolpate pollen
8Characteristics of Dicots
Dicot with two cotyledons on the right
Flower parts in multiples of five
Vascular bundles in rings
Net-veined leaves

10Copy and answer the ENTIRE question on your own
paper.
- 1. You collect a flower specimen while you are
out on a nature walk. It has 12 pink petals and
6 leaves with parallel veins around the flower.
Would you classify this plant as a monocot or a
dicot? Why? - 2. While out on the same nature walk, you
collect a blue flower. It has five flower petals
and leaves with webbed veins. It five leaves
around the petals. Would you classify this plant
as a monocot or a dicot? Why?
