Answers
Explanation:
Many marine, beach, pond, and swamp plants have waterborne seeds, which are buoyant by being enclosed in corky fruits or air-containing fruits or both; examples of these plants include water plantain, yellow flag, sea kale, sea rocket, sea beet, and all species of Rhizophoraceae, a family of mangrove plants. Sea dispersal of the coconut palm has been well proved; the fibrous mesocarp of the fruit, a giant drupe, provides buoyancy. Once the nuts are ashore, the mesocarp also aids in the aboveground germination process by collecting rainwater; in addition, the endosperm has in its “milk” a provision for seedling establishment on beaches without much fresh water. A sea rocket species with seeds highly resistant to seawater is gaining a foothold on volcanic Surtsey Island, south of Iceland. Purple loosestrife, monkey flower, Aster tripolium, and Juncus species (rushes) are often transported by water in the seedling stage.
