1 the global level (how it's important to ecosystems), 2  the plant part level (how leaves are organized for the process), 3  and/or the cellular level (the chemical reactions occuring in the chloroplasts of the plant cells in the leaves of the plant).
Jupiter has 67 known moons, although 17 of them are awaiting official names. More are discovered with every space probe we send there. It is likely that there are more not yet identified. The most recent are extremely small.
Since 2003, 16 additional moons have been discovered but not yet named, bringing the total number of known moons of Jupiter to 67. As of 2013, this is the most of any planet in the Solar System; but additional undiscovered, tiny moons may exist.
