Epithelial tissue protects your body from moisture loss‚ bacteria‚ and internal injury. There are two kinds of epithelial tissues: Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example‚ the outermost layer of your skin and other organs‚ and the internal surface lining of your lymph vessels and digestive tract.

The cell‚ which is the smallest unit of life‚ is surrounded by a plasma membrane. The plasma membrane functions somewhat like a wall‚ as it keeps the internal contents from the external environment. Just like a wall‚ the membrane is also somewhat permeable‚ except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out. The plasma membrane is a very thin structure‚ which has some very important tasks. One of the main tasks that it performs

EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the
