Structure of the Mn 4 O 5 Ca core of the oxygen-evolving site in plants, illustrating one of many roles of the trace mineral manganese. [38] The list of minerals required for plants is similar to that for animals. Both use very similar enzymes, although differences exist. For example, legumes host molybdenum-containing nitrogenase, but animals ...

These include: O 2 and CO 2 (mainly from the air via leaves) and H 2 O, NO − 3, H 2 PO − 4 and SO 2− 4 (mainly from the soil water via roots). Plants produce oxygen gas (O 2) along with glucose during photosynthesis but then require O 2 to undergo aerobic cellular respiration and break down this glucose to produce ATP.
