What is the function of rhizoids?

Rhizoids:

1. A rhizoid is a short, thin filament that may be found in fungus, plants, and sponges.
2. It links the organism's growing body to a substratum and is capable of absorbing vital nutrients.
3. The rhizoid is a root-like structure found in the thallus of fungi.

The function of rhizoids:

1. Rhizoids operate as roots, basically attaching the plants to the surface.
2. It can function as a feeding organ, as in Rhizopus, or as an anchoring organ, as in Chytridium.
3. In plants, such as liverworts and mosses in the division Bryophyta, rhizoids bind the gametophyte to the substratum and aid in mineral and water absorption.
