A conical or branching body, by which a seaweed is attached to its support, and differing from a root in that it is not specially absorbent of moisture.
An organ of a benthic alga that attaches the alga to the seafloor.
A specialized structure that attaches a thallus to the substrate. It may consist of a secreted substance with a characteristic shape, or the entire basal cell of the thallus (the holdfast cell) may be modified for attachment.
the root-like part of a seaweed. The holdfast attaches the seaweed to a hard surface.
attachment organ or macro-algae.
An algal-free thickeded mass of hyphae used for attachment. For example, the organ of attachment of Usnea, old man's beard.
restraint that attaches to something or holds something in place
a rootlike plant structure that anchors a seaweed
algal organ for attachment
A structure anchoring seaweed to rocks and other hard surfaces.
the part of a seaweed that anchors it to the ground or a hard surface. Unlike true roots, this merely grips the surface and does not absorb water or nutrients.
root-like tendrils that attach the sponge to rocks.
The part of the alga that holds it to the substrata.
the root analog in seaweed, used to anchor the thallus (body).
Root-like structure which anchors a seaweed
Anchoring base of an alga.
A holdfast is the root-like structure of kelp that holds the base of the plant in place on the sea floor. Unlike real roots, however, the holdfast does not obtain and supply nutrients to the rest of the plant.
The root-like base of marine algae that anchors or attaches the plant to the substrate. The root-like part of the thallus.
projection from the thallus which attaches the thallus to a surface, may be called an appressorium in the higher fungi.
