Seed Dispersal

How do plants spread their seeds?

Seeds Spread by the Wind

• Small seeds• “parachute” or

“wing-like structure”

Spread by Water

• Seeds have thick shell to protect from waves and rocks.

• Buoyant so they can float along in river or ocean currents

Seeds Spread by Animals

• Small hooks catch on animal fur as they pass by

• Seeds are dispersed later as animals lick, bite or rub them off

Seeds Spread by Animals• Deer eat fruit • Seeds are not destroyed

as they move through the animal’s digestive system

• Seeds are dispersed in the animal’s poop

• Squirrels hide nuts each year but for the winter but forget where some are located
