THALLUS Meaning and
Definition
-
Thallus is a noun that refers to the vegetative body of a nonflowering plant, such as algae, fungi, and lichens. It is a structurally undifferentiated or relatively simple flattened structure that lacks true leaves, roots, or stems, and serves as the primary organ for photosynthesis and nutrient absorption.
In algae, the thallus can range from unicellular to multicellular, with the latter often forming a filamentous or sheet-like structure. These thalli are typically composed of distinct pigmented cells and are responsible for both food production and reproduction.
Thalli in fungi are most commonly seen in the form of a mycelium, a network of hyphae that collectively constitutes the vegetative body. These thalli are highly adaptable and allow fungi to grow on diverse substrates, decompose organic matter, and perform other important ecological functions.
In lichens, which are a symbiotic association between a fungus and an alga or a cyanobacterium, the thallus represents the combined body of both partners. The fungal hyphae provide a supportive structure while the algal or cyanobacterial cells carry out photosynthesis.
Overall, the thallus is a crucial feature in nonflowering plants. It acts as a flexible, adaptable, and functional body structure that enables these organisms to survive and thrive in various environments, contributing to their ecological significance and diversity.
