Pollen is the male contribution
to plant reproduction. It equates to Sperm in Animals and needs to
get to the egg to complete Fertilization. This process of Pollination is
necessary for most Plants to bear Fruit, Vegetables, and Seeds. The Pollen
can come from the same plant in some species, and from other nearby plants
in other species.
This transfer of Pollen can be
made by Bees, Beetles, Flies, Moths, Wasps, Butterflies, Animals, Birds,
Spiders, Wind, Lawnmowers, or your Pollination Brush. The International
value of Pollination is priceless since it supports life as we know it.
1- Some
Blooms, like the Hibiscus shown above, may lack natural pollinators because
they are less attractive than other nearby plants which bloom at the same
time. Then the Insects will visit the more attractive Flowers instead.
Plants may also have been imported
from a country which has natural pollinators which do not exist in your
area. Some Plants are so Pollinator specific that if their Pollinator becomes
extinct, so does the Plant .
2-
This Solitary Bee is dusted with yellow Pollen from the Plants it has been
visiting. Here it will crawl into the hole which a friendly Gardener has
provided for it, and deposit Pollen or a caterpillar in the cavity. Then
it will re-enter the hole tail-first to deposit an egg. When the cavity
is full of eggs and food, it will seal the hole and start a new one.
3-
Here a BumbleBee hangs upside-down on a Tomato Blossom, with its load of
yellow Pollen. Some BumbleBees are Solitary and some have small colonies
of several individuals which may share the chores of raising Brood.
4-
This Honey Bee is fanning its wings in preparation for flight after it
filled its leg "baskets" made of hair, with Pollen from nearby Flowers.
5-
Here a Wasp unintentionally Pollinates a Wild Garlic Flower while searching
for Nectar and tiny Insects.
6-
Butterflies Pollinate Flowers as they stick their long Proboscis into the
tiny Flowerlets to reach their favorite sweets. Some of these "drinking
straws" are several inches long.
7-
This Sphinx Moth hovers over a Butterfly Weed like a Humming Bird, while
its long Proboscis darts down into the sweet secretion below. More Pollinators
can be seen HERE.
If you have Plants which fail
to produce Seeds or Fruit, you may opt for the easy and enjoyable art of
Hand Pollination, using simple, inexpensive, and readily available supplies.

A
small Artist's Brush is the Pollen transferring tool of choice. It is gently
touched to the Pollen on the Anther and then touched to the Stigma, which
is itself often sticky enough to hold the Pollen while the necessary components
are transferred to the Egg.
If you desire to determine which
Pollen is transferred to a Stigma, then you will have to isolate the Bloom
from outside sources of Pollen. A Paper Bag will accomplish this nicely.
Plastic could be used, but it contributes to the growth of mold and mildew
and potential loss of your experiment.
Upon fertilization, the Flower
begins to form Fruit and Seeds. In the case of Apples or Tomatoes, the
Seeds are inside the Fruit. In the case of Beans and Peas, the "Fruit"
is the Seed. In the case of many Flowers, edible Fruit is not the goal.
Instead, a Pod may contain a few or many dozens of Seeds.
