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.

Prothallus and thallus are both structures found in certain plants, but they differ in their characteristics and functions. A prothallus is a small, flat, and heart-shaped structure that is produced by ferns during their reproductive cycle.

Apr 15, 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.)

Aug 16, 2024 · Algae are simple, chlorophyll-containing organisms classified within the plant kingdom but distinct from higher plants. These organisms possess a plant body known as a thallus, which lacks the differentiation into roots, stems, or leaves typically observed in more complex plants.

A thallus is a simple, undifferentiated body structure found in some plants, particularly algae, that does not have true stems, leaves, or roots. This structure enables organisms like green algae to adapt and thrive in aquatic environments, showcasing how early plant forms may have evolved before more complex structures developed in land plants.

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.

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.
