Pollination and Dispersal

Pollination Strategies

Wind Pollination Small petals, exposed parts

Wind Pollination Lots of pollen ragweed pollen

Water Pollination Uncommon Floating parts

Animal Pollination - Bee Shallow flowers and bright colors Purple, yellow “targets”

Animal Pollination - Butterfly Long, narrow tube Bright colors

Dispersal Strategies “The apple may not fall far from the tree, but the seeds can go a long way.”

Wind Dispersal Dry fruits Float easily Shaped for gliding

Water Dispersal Fruits can float Why did you think palm trees grow on the beach…to get a tan?

Animal Dispersal - Sticking Fruits have hooked barbs to stick to animal fur (or clothes!)

Animal Dispersal – Passing Through Seeds need to be eaten Fruits are colorful and sugary Ripen when seeds are mature
