Fifth step of collagen synthesis
Organelle which stains dark due to rRNA
Cells responsible for main function of organ
Muscle fibers which transmit sensory information
Gives rough ER it's name
Tissue where collagen fibers are arranged without definite orientation
Cell division which produces 2 haploid cells
Component of microfilament
Flattened/elongated top nuclei, multiple layers, dark top layer
Cells vary in height, but tend to be as long as they are tall
DefintionTerm
Proteins which span the bilayer
First step of collagen synthesis
Cells appear to be in layers, but all cells are in contact with basement membrane
