... Seagrasses form extensive beds or meadows, which can be either monospecific (made up of one species) or multispecific (where more than one species co-exist). In temperate areas, usually one or a few species dominate (like the eelgrass Zostera marina in the North Atlantic), whereas tropical beds usu ...

... The auxin from the top of the plant, the apical meristem is produced in relatively high conc, so the shoot is stimulated. However the lateral buds remain dormant as high concs of auxin inhibit their growth. As the auxin diffuses down the plant it becomes less concentrated, and is inactivated by enzy ...
