3 ways in which pollen gets from flower to flower, and which way is used by the majority of plants?
1. They don't; obligate selfers-- plants/flowers self pollinate
2. Abiotic: Wind, water
3. Biotic: insects, birds, bats, etc etc etc (used by majority)

Explain pollination syndrome.
- correlated suite of floral traits evolved in response to a particular type of pollinator. Typically, diffuse coevolution between groups of plants and animals.

Define diaspore. What is the cost and benefit?
= Any part of an organism capable of dispersing, give rise to new individual.
Cost: use of resources, risk of predation, not encountering better environment
Benefit: might encounter more favorable environment.

Cost to plant (animal pollination) 3 things:
. advertisement (petals, scent)
. reward (nectar, pollen, floral parts)
. potential damage
. reward (nectar, pollen, floral parts)
. potential damage

Name 2 benefits to plant (animal pollinators):
- animal vectors more reliable/efficient than wind
- increased potential for outcrossing
- increased potential for outcrossing
