Holdfasts anchor large algae to the ocean floor. They substitute for roots:)
filum terminale
Most macroalgae (multicellular algae) are made up of three parts. The blade is a leaf-like structure that captures light and carries on photosynthesis. The stipe is the stem of the algae. The holdfast is the anchor for the algae; it holds the algae to a solid surface such as a rock or pier. Although the holdfast may look like roots, it does not function to get nutrients or water. Some algae may have a fourth structure, the pneumatocyst; this structure is an air bladder on the stipe or blade that functions to keep the algae afloat in the water column.

The ciliary body is a specialized structure which anchors the iris with the choroid. It makes aqueous humor and anchors the lens via the zonules, through which it modulates lens changes.The ciliary body is a specialized structure which anchors the iris with the choroid.

That anchoring structure is called the placenta.
The basal body is a structure that anchors the base of the flagellum and allows it to rotate.
Two styles of anchors are heavy and light anchors. Types of anchors are as follows: Danforth anchors, plow anchors, spade anchors, Delta anchors, claw anchors, mushroom anchors, and navy anchors.
They are called rhizoids.
