Thallus or Thallos (Greek: Θαλλός), perhaps a Samaritan, [1] was an early historian who wrote in Koine Greek. He wrote a three-volume history of the Mediterranean world from before the Trojan War to the 167th Olympiad, 112–108 BC, or perhaps to the 217th Olympiad (AD 89-93) or 207th Olympiad (AD 49-52).

Thallus (pl.: thalli), from Latinized Greek θαλλός (thallos), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria.

Thallus, plant body of algae, fungi, and other lower organisms formerly assigned to the obsolete group Thallophyta. A thallus is composed of filaments or plates of cells and ranges in size from a unicellular structure to a complex treelike form.

The meaning of THALLUS is a plantlike vegetative body (as of algae, fungi, or mosses) that lacks differentiation into distinct parts (such as stem, leaves, and roots) and does not grow from an apical point.

Mar 28, 2025 · Fungus - Structure, Reproduction, Nutrition: In almost all fungi the hyphae that make up the thallus have cell walls. (The thalli of the true slime molds lack cell walls and, for this and other reasons, are classified as protists rather than fungi.)

Mar 9, 2024 · Thalloid refers to a plant or organism resembling a thallus, a simple, undifferentiated structure, while thallus is the actual body of algae, fungi, or non-vascular plants, lacking true stems, roots, or leaves.

Mar 28, 2024 · Thallus is a plant body without true stems, leaves, or roots, found in algae and fungi, while mycelium is the network of fungal filaments (hyphae) vital for growth and nutrient absorption.

The thallus (Fig. 3) is a multicellular unit with a restricted number of cells, derived from two-celled ascospores through a defined number of mitotic divisions in multiple planes (Blackwell et al., 2020). A primary septum separates the larger cell of the ascospore from the smaller one.

Thallus refers to the vegetative tissue of some organisms in which these tissues are not organized into organs. Thalli do not have organized parts such as leaves, roots, stems, branches as well as vascular bundles.

What is the Importance of Thallus? The thallus is a special part of the body of fungi. Due to the presence of cell walls, it is known as the plant body part of fungi. This is where the fungi is similar to plants. The main thing you can find in the thallus is the filaments.
