Plants don't obtain their food from soil in the way animals obtain food by eating. Through photosynthesis, they produce sugars using light, carbon dioxide, and water.
Their roots mainly need access to water, oxygen, and essential mineral...
Certain plants can generate heat through a process known as thermogenesis.
Species including some arums and lotuses can maintain parts of their flowers at temperatures noticeably above the surrounding air. Heat can help spread scent molecules...

Ocean waves and currents continually sort, transport, and reshape these...
Certain plants noticeably change the position of their leaves according to the day-night cycle.
This movement is called nyctinasty. Leaves may fold together, droop, or rise as light conditions change, with internal biological rhythms also...
