Identifying protiens(starch,gelatin,glucose) using the Biuret test |
Starch negative protien(blue) Glucose negative(Blue) Gelitin positive protein and turns (voilet) |
|
|
|
Detection of a polysccharide (starch) using (IKI) test iodiine pitassium iodine -organic molecule |
Starch (blue-black) positive Glucose -orange-negitive Gelutin -Orange - negitive |
|
|
|
Detection of monosaccharides (sugar) using Benedicts test |
Starch -blue-negityiive Glucose-orange brown- moderate sugar- positive Gelatin-blue-negitive The appearance of green , Orange, or brick red indicates presents of mono- or disaccharide |
|
|
|
Amino acids |
Protien polymers linked together by peptide bonds |
|
|
|
Osmosis |
when water movement is across and semipermeable membrane that allows water diffusion and prevent solutes diffusion |
|
|
|
Tonicity |
The measure of solute concentration |
|
|
|
Isotonic (iso=equal,same)! |
If the cell is in an environment in which the concentration of salute Is the same on both sides of the membrane The solution will be isotonic |
|
|
|
The cell is membrane is semipermeable |
Which allow movenent of certain substances in an out of thr cell and prevent other from doing so |
|
|
|
Hypertonic (hyper = more, higher) |
When the concentration of the solutes in EFC is higher the solution is |
|
|
|
Hypotonic (hyp= less ,lower) |
If it is lower it is |
|
|
|
Epithelial tissue |
Covers the body and organs , and lines cavities , tubes and hollow organs. MAJOR Characteristics are basement membrane which connects it to the uderlying connection tissue. It has free apical surface- the cell face open space , surrounding of body lumen of a tube or organ |
It is avascular = no blood |
|
|
Shapes of cells |
Squamous- flat thin cell Columnar- taller than they are wide , appear almost rectangular Cuboidal- relatively cube like , appears almost square Transitional- the cell change shape due to the stretching of the organs they line Simple- single layer of cells Stratified - two or more layer of cells Pseudostratified - appears multilayer ed butin fact all cells are touching the basement membrane and are considered a single layerof cells |
