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

  2. Angiosperms have seeds enclosed in some type of fruit. • A flower is the reproductive structure of angiosperms. • A fruit is a mature ovary of a flower. • Angiosperms, or flowering plants

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

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

  5. A cotyledon is an embryonic “seed leaf.” Botanists classify flowering plants into two groups based on seed type.

  6. Stem type can be woody or herbaceous. Wood is a fibrousmaterial made up ofdead cells. Wood has highconcentrations oflignin and cellulose. Woody stemsare stiff. Oak Flowering plants are also categorized by stem type and lifespan.

  7. Stem type can be woody or herbaceous. Wood is a fibrousmaterial made up ofdead cells. Wood has highconcentrations oflignin and cellulose. Woody stemsare stiff. Flowering plants are also categorized by stem type and lifespan. • Herbaceous plants do not produce wood. Iris

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

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

  10. Annuals mature from seed, flower, and die in one year. • There are three types of plant life spans. • Biennials take two years to compete life cycle. • Perennials live more than two years. Big bluestem
