Answer 1

The correct answer is HoldfastKey Points

The root-like structure at the base of an alga that binds it to a hard substrate like a stone is called the holdfast.
The holdfast is similar to a plant root in that it anchors the organism in place.
However, unlike plant roots, the holdfast's sole function is attachment and it does not extract nutrients.

Additional Information

Some other parts of a seaweed:
- Stipe: The stalk of seaweed between the holdfast and blade, which resembles a stem
- Frond: The term used to refer to the stipe and blade together
- Seaweeds are often found in dense growths on rocky shores or in shallow water.
- They are commercially important to humans and are used as fertilizers or as sources of polysaccharides
- The midrib is the central vein of a leaf that runs from the leaf base to the tip.
