Monsanto held a ribbon-cutting ceremony on Friday to open 36 new greenhouses at its Chesterfield Research Center.

The celebration of the state-of-the-art greenhouses was held against the backdrop of last month's announcement that Bayer will buy Monsanto in a $66 billion deal.

Monsanto CEO Hugh Grant told the crowd, made up of mostly employees and a few members of the media, that Bayer's acquisition is an opportunity.
