Difference between pexoisome and proteosome Reticular connective tissue is found around the liver the kidney the spleen and lymph nodes as well as in bone marrow Function edit The fibers form a soft skeleton stroma to support the lymphoid organs lymph node stromal cells red bone marrow and spleen Osmium part of fixation for light microscopy it is the only fixing agent known which completely and easily fixes fats cilia and flagella are a 9 2 array a ring of nine microtubules is surrounded by two more microtubules Chemotaxis movement of an organism in response to a chemical stimulus Why is microfilament needed in endocytosis Be familiar w tissues that have intermediate filaments Tissue specific protein table 2 5 Nuclelos produce ribosomes from rRNA complex and proteins What does osteoblast do when they re in inactive form Whats osteocalcin SEM And TEM Difference HI Neha these are some of the differences SEM is based on scattered electrons while TEM is based on transmitted electrons SEM focuses on the sample s surface and its composition whereas TEM provides the details about internal composition Therefore TEM can show many characteristics of the sample such as morphology crystallization stress or even magnetic domains On the other hand SEM shows only the morphology of samples The sample in TEM has to be cut thinner whereas there is no such need with SEM sample TEM has much higher resolution than SEM SEM allows for large amount of sample to be analysed at a time whereas with TEM only small amount of sample can be analysed at a time SEM is used for surfaces powders polished etched microstructures IC chips chemical segregation whereas TEM is used for imaging of dislocations tiny precipitates grain boundaries and other defect structures in solids In TEM pictures are shown on fluorescent screens whereas in SEM picture is shown on monitor SEM also provides a 3 dimensional image while TEM provides a 2 dimensional picture
