Plants that are pollinated by wind produce much more pollen than plants that are pollinated by animals. why do you suppose this is so?

The wind does not deliver pollen directly to any particular plant. Pollinating animals are encouraged to visit the next flower. The wind deposits pollen everywhere at once. Wind pollinated plants therefore have a much greater area to cover, and produce more pollen.

A) acceleration. this seems to be the one that makes sense.

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
