EXHIBIT 20
Agriculture and gardening both depend on pollination, which is the transfer of pollen from the male part of a flower to the female part of (usually) another flower. This reproductive event is basically how flowers "have sex" but it is also how flowering plants produce fruits and seeds. Without pollination there is no agriculture, and without agriculture there would be insufficient food-production for the human population living on planet Earth. Most agricultural plants depend on various animals for pollination. Check out some pollination information (yeah, I said it!) below.
Directions to Exhibit 21
Turn so the Butterfly Garden is to your back. The small building with the big oak trees in front of it is C1, the Administration Building. Exhibit 21 is next to the oak tree on your right.
