membrane are composed of a lipid bilayer. their hydrophobic tails face the inside of the membrane and their hydrophilic heads face their environment.
The two major categories of body membranes are epithelial membranes and connective tissue membranes. Epithelial membranes include mucous membranes, serous membranes, and cutaneous membranes (skin). Connective tissue membranes include synovial membranes that line joint cavities.
There seems to be a spelling error in your question. Perhaps you meant "endoplasmic reticulum" which is a network of membranes found in cells responsible for protein and lipid synthesis.
A mitochondrion has two membranes.
The types of membranes lining cavities that communicate with the exterior of the body are mucous membranes. These membranes are found in areas such as the respiratory, digestive, urinary, and reproductive tracts, and they secrete mucus to protect and lubricate the tissues.

Bifacial leaves are leaves that have photosynthetic cells on both the upper and lower surfaces, allowing them to capture sunlight from both sides for increased efficiency. This adaptation is often seen in plants that grow in low-light environments or have a need to maximize their photosynthetic potential.
