1. ANGIOSPERMS
One way to categorize angiosperms is based on their seed leaves (monocot or dicot). Monocots & Dicots have different characteristics.

2. Monocots & Dicots

3. Roots
MONOCOT
DICOT
xylem & phloem alternate usually surrounding a central core of cells (called pith). Found in fibrous roots.
xylem is in the center and forms an X shape. Phloem is between the arms of the X. Found in taproots.

4. Stems MONOCOT DICOT vascular bundles (of xylem & phloem) are scattered
one ring or concentric rings of vascular bundles

5. Leaves MONOCOT DICOT usually have parallel veins
branched or netlike veins

6. Petals MONOCOT DICOT petals in multiples of 3
petals in multiples of 4 or 5

7. Flower Organs Sepal: protects the flower bud
Petal: attracts pollinators

8. Flower Organs Stamen: male reproductive organs
Filament: stalk that supports the anther
Anther: holds pollen grains

9. Flower Organs Pistil/Carpel: female reproductive organs
Stigma: sticky. Where pollen grains land
Style: connects the stigma to the ovary
Ovary: contains the ovules (after fertilization these will mature into fruits)

11. Co-Evolution
Co-Evolution: influence of closely associated species on each other in their evolution
Animals and Plants have coevolved for pollination of plants. Examples include bright colors, strong scents, & sweet nectar to attract pollinators.
