While exploring a local park, Rhett observed various flowers and wondered which property is most likely to be exhibited by flower petals?

• hollow, to carry water and nutrients

• thick and sturdy, to support the stem

• brightly-colored, to attract pollinators

• green in color, to complete photosynthesis

Which example describes an abiotic method of seed dispersal?

• A seed is picked up and carried by the wind

• A squirrel collects seeds and stores them until spring

• A seed sticks to a raccoon’s fur and falls off in a new location

• A deer eats an apple, and the seeds come out in the deer’s waste

During a botanical garden visit, Jestin is observing the reproduction of flowering plants. Which structures are involved with fertilization in this process?

• leaf, ovary, anther

• anther, stalk, petal

• ovary, anther, pistil
