RHIZOID Meaning and
Definition
-
A rhizoid is a slender, root-like structure that is found in certain plants and fungi. It is typically tubular or filamentous in shape and functions as an anchoring and absorbing organ. Rhizoids are nonvascular, meaning they lack specialized tissues for conducting water and nutrients.
In plants, rhizoids are commonly observed in bryophytes such as mosses and liverworts. They emerge from the lower surface of the plant's gametophyte, which is the dominant multicellular phase in the lifecycle of these plants. Rhizoids play a crucial role in absorbing water and mineral salts from the environment. They also aid in anchoring the plant to the substrate, preventing it from being washed away by water currents or winds. Rhizoids are typically one cell thick and have fine projections called rhizoids hairs, which further increase their surface area for efficient nutrient absorption.
In fungi, rhizoids are similar structures that serve as the hyphae that anchor the fungal mycelium to the substrate. These specialized structures aid in obtaining nutrients for the fungus by secreting enzymes that break down organic matter. Rhizoids in fungi can be either superficial, growing above the substratum, or penetrating, growing into the substratum.
Overall, rhizoids are essential structures in various organisms, enabling them to absorb nutrients and anchor themselves in their respective habitats.

Etymology of RHIZOID
The word "rhizoid" is derived from the Greek word "rhiza", meaning "root", and the suffix "-oid", meaning "resembling" or "similar to". In biological terms, a rhizoid is a root-like structure that serves for anchorage, absorption, and sometimes as a means of asexual reproduction in certain non-vascular plants, fungi, and some algae.
