A close-up shot shows a person opening a small drawer in a museum exhibit. The exhibit has the Portuguese text "na macropomum] e o tucunaré habitam os rios da região amaz..." visible above the drawer. When the drawer is opened, a backlit display shows a close-up image of a green leaf of a Sumaúma tree. Underneath the leaf is the text "FOLHA DA SUMAÚMA" followed by a description of the leaf's function in absorbing carbon dioxide during photosynthesis and releasing water as vapor. The drawer is white on the inside, and the handle is a small, round silver knob. The person's hand is visible opening the drawer.
