Epidermis
The outer layer of our skin is composed of dead epithelial cells.
The tissue on the outermost part of your body is the skin, which is made up of epithelial tissue. The layer that comes into contact with the atmosphere is called the epidermis.
No. they are dead skin cells, or epithelial tissues. Lipids are fats
Dead bacteria and cells in the tissue form pus, which is a collection of white blood cells, dead tissue, and bacteria. The body's immune system responds to this as a sign of infection and works to eliminate it. Pus may need to be drained to facilitate healing.
xylem
Epithelial debris refers to the remnants of dead or damaged epithelial cells that can accumulate in various tissues or body fluids. This debris can arise from normal cellular turnover, injury, inflammation, or disease processes. In medical contexts, the presence of epithelial debris may indicate underlying conditions, such as infections or tissue damage, and can be assessed through laboratory tests or imaging studies. Its analysis can provide important diagnostic information regarding the health of epithelial tissues.
Dead bacteria and cells in tissue contribute to the formation of necrotic tissue or pus, depending on the context. Necrotic tissue results from cell death due to injury or infection, leading to inflammation and tissue breakdown. Pus, on the other hand, is a thick fluid that accumulates during an immune response, containing dead bacteria, dead cells, and immune cells. Both indicate an ongoing inflammatory process in the body.
no, its comprised of dead cells
yes that's what a scab is
A few layers of cells forms the basic packing tissue. This tissue is called parenchyma, A type of permanent tissue. It consists of relatively unspeciallised cells with thin cell walls. They are live cells. They are usually loosely packed and have large spaces between them. Then cholenchyma-this tissue provides support to plants and also stores food. In some situations, it contains chlorophyll and performs photosynthesis. Scalenchyma-this tissue makes plant hard and stiff. The cells of this tissue are dead. Example- bark of tree
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
