In Light microscopes and TEMs the beam of shed visible white ons/electrons pass by means of and through the objective, and there is an image produced as some parts of the exemplar absorb more light/electrons than others, but sometimes the ensample is transparent so it will facet white because light/electrons pass through so the object is stained Light Microscopeelectron Microscope Dye- usually methylene blue/eosinSpecimen immerge in metal like lead, the metal ions scatter electrons to contrast. 4. forebode the linear magnification of an image Magnification = Length of read / Length of specimen 5.Outline the functions of the structures. PictureDescriptionFunction Large and contains chromatin. enwrap by a nuclear envelope ? double membrane. atomic pores go through the envelope. Nucleolus inside.Nucleus contains the cells genetic material. Chromatin contains desoxyribonucleic acid and proteins which regulate cell activities. instructions for making prot eins. Flattened membrane- plaster casting sacs called cisternae, rough is studded with ribosomes, unflurried is not. RER transports proteins and SER is involved in lipoid synthesis. Stack of flat, membrane butt on stacks. [Pitta bread!]Golgi bole receives proteins from ER and modifies them. Packages proteins into vesicles to transport them ? exocytosis Sausage shaped. duple membrane marooned by fluid filled space. inner membrane is folded to form cristae and the middle part of the mitochondria is called the matrix. Site of aerobiotic respiration, ATP is produced. In plant cells. Double membrane. Membranous sacs called thylakoids, plural form=granum. plural=grana. Site of photosynthesis, carbohydrate molecules made. Spherical sacs surrounded by a single membrane, with no clear internal structure. Contains enzymes.Enzymes flaw taper cells. E.g. white blood cell lyosomes break push passel invading microorganisms and lyosome in the sperms head breaks d own(p) the material surrounding the egg. ! TINY.
