Examination of Nature’s Tissue Fibers: A Study of Cell Biology,Examination of the nature tissue fibers. Work 1. Boiling with alkalis. When boiled with alkalis (10% sol. NaOH or KOH) fiber of tissue of animal origin (silk, wool) are dissolved, of vegetable (cotton, flax) are just swell. The reaction is carried out in a test tube, into which add 2-3 ml of NaOH (KOH) solution and placed a piece of the examinated tissue. Boil on the spiritlamp (under the hood) 1-2 min.

Examination of Nature’s Tissue Fibers: A Study of Cell Biology

Tissue fibres are microscopic structures that are found in most living organisms. They are composed of proteins and other molecules that give tissues their structure and strength. The types of tissue fibres present in an organism depend on its evolutionary history and the environment in which it lives. For example, animals that live in water tend to have more collagen fibres, while terrestrial animals tend to have more elastin fibres. Understanding the structure and function of tissue fibres is an important part of cell biology and can help us better understand how organisms develop and evolve. Tissue fibres can be grouped into two main categories: collagen and elastin. Collagen fibres are strong and flexible and provide support to cells and tissues. Elastin fibres are more elastic, allowing tissues to stretch and compress. In addition, elastin fibres are important for cell motility, as they enable cells to move and change shape. Both collagen and elastin fibres are produced by cells and are essential for the survival and proper functioning of an organism (Holt et al., 2019; Sharma et al., 2020).
The structure of tissue fibres can be studied using a variety of techniques, such as electron microscopy and immunohistochemistry. Cont…
