The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
surfaces
Biofilms of microorganisms, especially cyanobacteria, are found on the outter surfaces of stromatolites.
They have rocky surfaces.

They cover the surfaces and the cavities of the body. Outer most layer of surfaces is an epithelial cell
receptors
Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
Excretion is the means by which waste material is removed from cells through the porous outer membrane.
Mostly on the inner and outer surfaces of the heart (pericardium & endocardium).
surfaces
Squamous epithelial cells are a sub-type of epithelial cells (cells which line glands and the inner and outer surfaces of the body). These cells are characterized as being very thin and flat epithelial cells and populate organs such as the skin and esophagus.

No. While prokaryotic Cells have their Cell Coats make from various mostly Cellulosic materials, eukaryotic Cells produce a [sugar-protein] glyco-callyx coat.
No the outer layer of the skin is not made of living cells. it is made of dead cells.
