Stain with basic dyes
Tissue where collagen fibers are arranged without definite orientation
Site of intracellular digestion
Fifth step of collagen synthesis
Responsible for movement of flagella and cilia

Collagen type in reticular tissue
Type of tissue that surrounds small blood vessels
Lightly stained areas in the nucleus
Non-differentiated/fused myoblast cells
Stain black with silver stain
Binds with elastin to form elastic fibers
Unicellular gland
Largest GAG/non-sulfated GAG
Muscle type that contains few mitochondria/myoglobin
Organelle which stains dark due to rRNA
Provides adhesion for epithelial cells
Fat cells where mitochondria produce heat
Proteins which span the bilayer
Outermost component of the cell
Cell capable of dividing but is not currently going through cell cycle
Fat cells where mitochondria produce ATP
Comprises interface between two cardiac muscle cells
Cells are taller than they are wide
Most common dye
Light bands of muscle
Cells appear to be in layers, but all cells are in contact with basement membrane
Reason why nucleolus is dark staining
Oxidizes hydrogen peroxide
Supporting tissue of organs
Adheres epithelial cell to basement membrane
Electron dense, coarse granules in the nucleus
Muscle type that contains abundant mitochondria/myoglobin
Cells are flat and very thin, single layer
Vesicle buds off and is secreted
Membrane formed by basal lamina and reticular lamina
Component of microfilament
Adheres one epithelial cell to another
Tissue where collagen bundles are in definite pattern
Flattened/elongated top nuclei, multiple layers, dark top layer

Flattened/elongated top nuclei, multiple layers, normal top layer
Gives rough ER it's name
Secretion of whole cell
