The purpose of holdfasts are to secure the algae in place, similar to how roots function, except they do not absorb nutrients like roots do.

What is a bundle of rootlike strands that attaches algae to rocks?
Holdfast
Are the stem holdfast and blade of brown algae the same as stems roots and leaves of land plants?
Algae have neither. Species of multicellular algae grow a body called a "thallus." A thallus may be simply a long string of cells, a bush-like or a feather-like structure, or a superficially plant-like structure, like those seen in kelp. The stem-like portions of a thallus (in those algae species that form a plant-like thallus) is sometimes called a "stipe." (The leaf-like portion is called a "blade," and the root-like portion called a "holdfast")
Which structure mediates the attachment of spores to a surface on which to grow?
a "root like" structure called a holdfast attaches spores to a surface on which they can grow.
What is the function of the air bladder of Fucus?
The Fucus is the a brown algae seaweed that comes with an air bladder. The bladder is filled with oxygen, nitrogen and carbon dioxide.
How many species of algae are there?
No one really knows. Estimates vary widely. The UK Biodiversity Steering Group Report estimated there to be 20,000 algal species in the UK.Most authorities place the known number of species between 5,000 and 20,000.
What is the structure that anchors an algae?
Holdfast.
What is a bundle of rootlike strands that attaches algae to rocks?
Holdfast
Which part of brown algae is most important in photosynthesis?
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.

What is the area of City of Holdfast Bay?
The area of City of Holdfast Bay is 13.72 square kilometers.
What is the function of chloroplasts in algae?
It has a universal function. It carry out photosynthesis
What is the function of chloroplast in greenplants and algae?
chloroplasts are organelles found in green plants and eukaryote algae
Is algae a type of moss?
Algae is not a type of mold. Algae is an organism that is far different in its function than mold.
What are characteristics found in seaside plants?
holdfast attachments
Why Sargassum has a strong holdfast?
due to sun light and photosynthesis.
