  • இழையம் (Tissue (biology)) (அல்லது திசு ) என்பது, ஒரு உயிர்ச் செயலைப் புரியும் ஒத்த பண்புகளுடைய உயிரணுக்களின் கூட்டமைப்பு ஆகும். (wikipedia.org)
  • In biology , tissue is a cellular organizational level between cells and a complete organ . (wikipedia.org)
  • cells
  • A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. (wikipedia.org)
  • For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals. (wikipedia.org)
  • By contrast, a true epithelial tissue is present only in a single layer of cells held together via occluding junctions called tight junctions , to create a selectively permeable barrier. (wikipedia.org)
  • Muscle cells form the active contractile tissue of the body known as muscle tissue or muscular tissue. (wikipedia.org)
  • Cells comprising the central nervous system and peripheral nervous system are classified as nervous (or neural) tissue. (wikipedia.org)
  • The epithelial tissues are formed by cells that cover the organ surfaces such as the surface of skin , the airways , the reproductive tract , and the inner lining of the digestive tract . (wikipedia.org)
  • It remains, therefore, a localized zone of specialized tissue, never becoming diluted by the interposition of expanding or differentiating cells. (britannica.com)
  • Clearly, if the division planes in a cell mass are randomly oriented and individual cells expand uniformly, the tissue will enlarge as a sphere. (britannica.com)
  • On the other hand, if cell division planes are oriented regularly or the expansion of individual cells is directional, the tissue can assume any of a number of shapes. (britannica.com)
  • Cells of a tissue have similar origin and structure. (sarthaks.com)
  • Meristematic tissues have thin-walled completely arranged immature cells. (sarthaks.com)
  • Structurally or functionally similar types of cells constitutes simple permanent tissues. (sarthaks.com)
  • We postulate that the high level of expression of ZmTIP1 in these tissues facilitates rapid flow of water through the tonoplast to permit osmotic equilibration between the cytosol and the vacuolar content, and to permit rapid transcellular water flow through living cells when required. (plantphysiol.org)
  • In this paper we use in situ hybridization to examine the expression pattern of ZmTIP1 , a highly expressed tonoplast aquaporin of maize, in tissues and cells involved in water and solute uptake and transport. (plantphysiol.org)
  • Tissue is a group of cells with more or less common origin and doing a specific function. (easybiologyclass.com)
  • growth
  • The geometrical arrangements in the particular organ determine the way in which this occurs, but in general the consequence is that the meristem is continuously moving away from the maturing tissue as growth continues. (britannica.com)
  • frozen tissue
  • In the last couple of decades, developments in electron microscopy , immunofluorescence , and the use of frozen tissue sections have enhanced the detail that can be observed in tissues. (wikipedia.org)
  • forms
  • In the peripheral nervous system, neural tissues forms the cranial nerves and spinal nerves , inclusive of the motor neurons . (wikipedia.org)
  • contrast
  • In contrast, water and solutes that enter these principal conduits pass through living tissues and may encounter membrane barriers when they follow the transcellular path. (plantphysiol.org)
  • leaf
  • This is accomplished by slicing up a leaf (or other tissue) and then floating it in a solution containing wall-digesting enzymes like cellulase suspended in an inert osmotic agent in a buffered solution. (csbsju.edu)
  • water
  • Cell-to-cell flow can be a major transport route for water, although the extent to which water also follows an apoplastic path is still a matter of debate and may depend on the organ or tissue, its stage of development, or its physiological state. (plantphysiol.org)
  • come
  • This tissue covers all organismal surfaces that come in contact with the external environment such as the skin , the airways, and the digestive tract. (wikipedia.org)
  • human
  • Microscopic view of a histologic specimen of human lung tissue stained with hematoxylin and eosin . (wikipedia.org)
