USS Aries Arboretum - Cutaway View

Like most ships of Starfleet, the Aries also has an Arboretum. Sporting a more unique design than the rest of the fleet, the Zodiac class also has a distinct Arboretum. With support for up to six biomes, the Science team has managed to make several species from across the Federation grow.  All designed to help with air purification, they were also chosen for each species appreciation for the plants beauty. Aside from some basic science, and a back-up air purifier, the Arboretum also functions as a another crew lounge along with a place to host visiting dignitaries and VIPs. The front area is kept darker, partly for the Andorian vines, but also to enable more practical stargazing out of the viewports.

Built everything you see here except for:
The Ivy was generated with Ivy Generator - an open source app - and is custom wound around the parts of the set. 
The rest of the plants are available from DAZ.
