KEY CONCEPTThe largest phylum in the plant kingdom is the flowering plants.
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.
Fruit allows for efficient seed dispersal. • Fruit is flower’s ripened ovary • Surrounds and protects seed(s) • Many forms, each function in seed dispersal
Based on the number of cotyledons(an embryonic “seed leaf”) (this is like the first sprout from the seed) Monocots have a single seed leaf. leaf veins usually parallel flower parts usually in multiples of 3 bundles of vascular tissue scattered in stem Botanists classify flowering plants into two groups based on seed type.
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
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.

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