1. KEY CONCEPT The largest phylum in the plant kingdom is the flowering plants.

2. Flowering plants have unique adaptations that allow them to dominate in today’s world.
Flowers allow for efficient pollination.
animals feed on pollen or nectar
pollen is spread from plant to plant in process

3. Fruit allows for efficient seed dispersal.
Fruit is flower’s ripened ovary
Surrounds and protects seed(s)
Many forms, each function in seed dispersal

4. Botanists classify flowering plants into two groups based on seed type.
A cotyledon is an embryonic “seed leaf.”
Monocots have:
a single seed leaf.
leaf veins usually parallel
flower parts usually in multiples of 3
bundles of vascular tissue scattered in stem

5. Dicots have
two seed leaves.
leaf veins usually netlike
flower parts usually in multiples of 4 or 5
bundles of vascular tissue in rings in stem

6. Flowering plants are also categorized by stem type and lifespan.
Stem type can be woody or herbaceous.
Wood is a fibrous material made up of dead cells.
Wood has high concentrations of lignin and cellulose.

Herbaceous plants are softer and more flexible.

8. There are three types of plant life spans.
1. Annuals mature from seed, flower, and die in one year.
Wheat

9. There are three types of plant life spans.
1. Annuals mature from seed, flower, and die in one year.
2. Biennials take two years to compete life cycle.
