1. Dispersed by the agency of water; such as, floating seeds, fruits, or vegetable parts: Mangrove trees utilize hydrochores as a means of reproducing because they live in water and when their seeds fall down, they grow roots as soon as they touch any kind of soil.
During low tides, these processes of hydrochores might fall in soil instead of water and start growing right where they fall; however, if the water level is high, they can be carried far away from where they fell.2. A dependence on water for dissemination.
