The cells above the stratum basale were polygonal cells with central nucleus and cytoplasm filled with rough endoplasmic reticulum, ribosome, golgi apparatus and tonofibril.
Clathrin-coated pits and vesicles Both endocytosis of material at the plasma membrane and exocytosis from the Golgi apparatus involve the formation of clathrin-coated pits and vesicles.
Enclosed in a bubble made of the same material as the cell membrane, the golgi apparatus also gives the antibody directions, telling it how to get to the edge of the cell.
So you know the golgi apparatus, endoplasmic reticulum, lysosomes, vesicles, all these things are made, we think, from the in folding of this what's called the endomembrane system or membrane on the inside.
