9. Structure: electron micrograph of hepatocyte (EM 5)Identification: nuclear envelope, inner and outer membrane, nuclear poresNuclear envelopeHeterochromatinEuchromatinNuclear pore

10. EM 2bnucleuscytoplasm

36. Cells in mitosis32409

37. EM 10f: Arteriolar wall; 30,000x.Apical caveolaeCollagenDense bodiesElastic fiberEndothelial cellNuclear poreRER

38.

39. EM 19c: Sertoli cell; 13,300x.GolgiHeterophagic vacuoleLipid dropletMicrotubuleNuclear pores (cross-section)Sertoli cellSynaptoneural complex

40. Colchicine treatment – chromosomes do not separate and NE forms around each chromosome due to breakdown of MT.Multinucleated cell

41.

42. Cytochalasin B treatment-breaks down microfilaments-nucleus activity but cells do not undergo cytokinesisBinucleated cellNucleolusCytochalasin B treatment – chromosomes separate into two normal size nuclei, but the cytoplasm does not split in two
