Pollen DispersalPollen DispersalPollen DispersalPollen Dispersal• Animals

– pollen is usually barbed or sticky

– Mammals, birds, insects (bees, flies, etc.)• Wind

– pollen is usually light & aerodynamic

• Water – for plants that grow underwater

Seed DispersalSeed DispersalSeed DispersalSeed Dispersal

• Dispersal: movement away from an existing population

• Animals– Birds: reliant on color when finding food –

red, hot pink, orange. – Mammals: seeds pass through digestive

system, may contain laxative– Insects: have excellent senses of smell or

color vision or both

Seed DispersalSeed DispersalSeed DispersalSeed Dispersal• Wind

– Usually light (low density) & aerodynamic

– May have wings

• Water – For plants that grow in or near

large bodies of water (eg. coconut)

– Low density: float– Must be somewhat waterproof

1b. Is a pumpkin a fruit? Describe any evidence you use in making your inference.1b. A pumpkin is a fruit. A pumpkin forms the ovary of a flower and it has seeds inside.

2a. Describe two methods of seed dispersal.2a. Methods of seed dispersal include movement of seeds by animals, wind, and water.

2b. A new angiosperm species is discovered. What questions would you ask before predicting how its seeds are dispersed? Explain the rationale for asking each question.2b. Your response here! Example: Is the fruit fleshly? If yes, then it will probably be eaten by animals. Are the fruits dry, light weight, or buoyant? If yes, they may be dispersed by wind or water.

3b. Why is it adaptive for some seeds to remain dormant before they germinate?3b. Dormancy enables a seed to survive until environmental conditions become favorable. Dormancy may also allow for long-distance dispersal.

3c. The seeds of a bishop pine germinate only after exposure to the extreme heat of a forest fire. Evaluate the significance of this structural adaptation.3c. Since most of the trees in the forest will be destroyed by the fire, this adaption decreases competition for resources, thus creating a favorable environment. It also helps ensure that the species will survive fires.
