Veneer Core Hardwood Plywood (VC). Veneer Core plywood is made from alternating layers of fir slices (common plywood) with a surface veneer of a finished woodgrain such as oak or maple. This construction gives VC plywood a distinct advantage over others in strength.or a 1/2 sheet, there are typically 7 to 9 plies. Being birch, the surface does not finish as nicely as the maple counterpart, and there is a tendency for splintering at the edge of a machined cut. Appleply Appleply is a manufacturer's name for high density maple plywood.
In cell biology, an organelle /ÉrÉ¡ÉËnÉl/ is a specialized subunit within a cell that has a specific function.nder the more restricted definition of membrane-bound structures, some parts of the cell do not qualify as organelles. Nevertheless, the use of organelle to refer to non-membrane bound structures such as ribosomes is common. This has led some texts to delineate between membrane-bound and non-membrane bound organelles.
Membrane-bound organelles. Eukaryotic cells contain collections of proteins that function as a unit called organelles. Some of these organelles are surrounded by a membrane similar in structure to the cell membrane but with a different composition of protein and phospholipid.Membrane-bound organelles offer several advantages to eukaryotic cells.ome of these organelles are surrounded by a membrane similar in structure to the cell membrane but with a different composition of protein and phospholipid.
