Welcome to the Pollination Department
1
Every place on Earth is an ecosystem, including our club site.
In today’s club adventure we will investigate pollination eco-services…

bees even do headstands for it! 5
Pollination is so much fun…,
Pollination is:1) Another name for the country of Polli
2) A new way to take a survey
3) How plants reproduce 6
If you guessed…. how most plants reproduce
You were right! 7
Let’s look at the parts of a flower.Male parts: stamens (anther and filament)
Female parts: pistil (stigma, style, ovary)
8
Flower Parts
Most flowers have both male and female parts, and it is best if pollen goes from one plant to the stigma of a different plant.
9
Here’s another
kind of flower, an Easter lily.
10
How do plants make sure that pollen goes from one plant to another?
Separate male and female flowers
11
Or plants might make sure that the male & female flower parts mature at different times.

Suga has lots of workers.Let’s meet some of them.

Why do pollinators visit flowers?
• To collect pollen. It is used as food for bee larvae.
23
Why do pollinators visit flowers?
• To collect nectar. It provides energy for the pollinator or its young.
24
What attracts pollinators to flowers?
•Flower color
•Flower odor
•Deception
25
Let’s stand up and pretend we are bees.
Adaptations for Pollinators:
• Red color• Flowers with
a tube shape• Large
amounts of sweet nectar
• Open during day
Hummingbirds often visit flowers that have:
Adaptations for Pollinators:
• White color• Flowers with a
tube shape• Large
amounts of sweet nectar
• Open during night
Hawkmoths often visit flowers that have:
Adaptations for Pollinators:Butterflies
• Many colors• Flower clusters
to land on• Odorless• Small floral
tubes with nectar
Adaptations for Pollinators:
•Tiny flowers•Many flower
parts missing
•No nectar•Open during
day or night
Wind pollinated plants have:
Adaptations for Pollinators:Bees are the most common and
important pollinators.
• Color: yellow, blue, white
• Short tube• Sweet scent• Ultraviolet

Threats to Pollinators
Pollinators are threatened by:
• Use of pesticides
• Lack of host plants
• Destruction of habitat
37
How can you help pollinators?• Don’t use pesticides
in areas where pollinators are visiting.
• Plant many different kinds of plants to provide nectar during the entire growing season.
• Leave some bare areas as homes for ground nesting bees.
What can we do to help the Pollination Department at our
site?
