How Do Flowers & Bees Help Each Other? | Sciencing
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma . The quality of pollinator service has declined over time and this had led to concerns that pollination will be less resistant to extinction All these relations together form a network of interactions between plants and pollinators. Flowering plants and bees share a mutualistic relationship, wherein flowers provide bees with food, and bees provide flowering plants with the. Much remains to be learned about pollinators and plants. Carol Ann of depen- dence and linkage in pollination sys- .. serves in Costa Rica and determined.
For example, bottle gentian has large, tightly-closed flowers that exclude most pollinators.
However, large bumblebees are strong enough to pry open the petals and crawl inside. Some flowers have developed such specialized relationships that they can only be pollinated by a single species.Pollination - the delicate balance between bees and flowers - Jennifer Leavey - TEDxGeorgiaTechSalon
Cacao trees, from which we get chocolate, have tiny, complex flowers that can only be pollinated by a teeny midge fly. In Madagascar, Charles Darwin encountered an orchid that has an inch deep flower. He reasoned there must be a pollinator with specialized equipment to feed from that flower, and sure enough, many years later, a moth with an inch long proboscis was discovered. Activity—Matching Flowers to Their Perfect Pollinator Partners Such unique, specialized relationships are not common, but you and your students can explore everyday flowers and their pollinator partners with the following activity: Discuss the ways plants use their flowers to attract pollinators—shape, color, smell.
Then look at each type of flower in your classroom sample and pose the following questions: Attempted copulation places the male in such a position that pollen sacs are attached to his body in a position that place the pollen on a stigma of another mimic flower with whom he "copulates".
So remarkable is the "fit" between pollinator and flower in many instances that one can often predict the type of pollinator a flower is adapted for by examining the flower's color, shape, scent, and other characteristics. Thus, pollinators and the plants they pollinate serve as examples of co-evolution. Review the material on flower structure from a previous topic. Then examine the table below that shows some common characteristics of flowers that are associated with the attraction of certain pollinators.
View Table 1 Note how the flowers' shape and color "fit" physiological and behavioral traits of their pollinators.
Birds, butterflies and moths "hover" while pollinating, so stigmas and anthers often protrude beyond the petals. Butterflies use color displays in matings and are attracted to bright colors.
Pollinator - Wikipedia
Butterfly-pollinated flowers are usually bright red, orange, or pink and open during the day when most butterflies are active. Moths, in contrast, are nocturnal and usually find females by following a pheromonal or chemical trail.
Moth-pollinated flowers are usually white or pale yellow with a heavy fragrance. Sciencing Video Vault After collecting nectar and pollen from many different flowers, bees fly back to their colonies.
What is Pollination?
They regurgitate nectar, mixed with enzymes, and expose the mixture to the air for several days, creating honey. This honey is used to feed the colony.
Pollen is mixed with nectar to form a protein-rich substance called beebread. Beebread is primarily used to feed young developing bees, called larvae. How Flowers Benefit From Bees Bees benefit flowering plants by helping the plants reproduce, via pollination. Because plants cannot seek out mates the way animals do, they must rely on outside agents, called vectors, to move their genetic material from one plant to another.

Such vectors include bees, certain birds and wind. Flowering plants carry the male portion of their genetic material in their pollen.
When bees fly from one flower to another, pollen is spread from plant to plant. If pollen from one flower is able to reach another flower of the same species, then that plant will be able to form seeds and reproduce.
