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

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

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

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. Woody stems are stiff. Oak

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