A thallus typically names the whole body of a multicellular stationary creature wherein there is no association of the tissues into organs. Even however thalli don't have coordinated and unmistakable parts (leaves, roots, and stems) as do the vascular plants, they might have comparable to structures that look like their vascular "counterparts". The closely resembling structures have comparative capacity or naturally visible design, however unique minute construction; for instance, no thallus has vascular tissue. In extraordinary cases like the Lemnoideae, where the design of a vascular plant is indeed thallus-like, it is alluded to as having a thalloid construction, or in some cases as a thalloid. Albeit a thallus is generally undifferentiated as far as its life systems, there can be noticeable contrasts and practical contrasts. A kelp, for instance, may have its thallus isolated into three locales. The pieces of a kelp thallus incorporate the holdfast (anchor), stipe (upholds the edges) and the edges (for photosynthesis).
