Document Summary
Acb 3309 lecture 1 structural basis of cell bio. Course goals: describe how tissues are structured to perform various functions. Integrate knowledge gained in this course with your other life science courses. Histology: the study of the microscopic structure of tissues and organs. Tissue: a group of similar cells and their products that have a common function. Yellow = inner lining = endothelium (non-thrombogenic lining so prevents blood from clotting in the vessel) Chemical composition of tissues: carbohydrates, energy storage system stained or washed out bc of way section is prepared. In animals, cellular structure is mitochondria, polymer is glycogen, monomer is glucose. In plants, cellular structure is chloroplast and polymer is starch: nucleic acids, blueprints of cells, tissues and our body. Found in dna and rna: proteins, lipids, energy storage system, need to colour (stain) these macromolecules to see them. Light microscope resolution = 0. 2 um (200nm: routine slide preparation.
