Epithelial tissue always has an exposed outer surface anchored to connective tissue by a thin, non-cellular structure called the basement membrane.
<h3>What is the basement membrane? </h3>
Thin layers of a specialized extracellular matrix that form the supporting structure supporting the growth of epithelial and endothelial cells are called the basement membranes. They surround the muscle and fat cells and the Schwann cells of peripheral nerves.
There is one common denominator regarding the basement membrane. This is because they are always in close opposition to cells.
It has been well demonstrated that basement membranes are not only for the provision of mechanical support and for dividing the tissues into compartments but also influence cellular behavior.
Collagen IV,laminin-entactin/nidogen complexes, and proteoglycans are the major molecular components of the basement membrane.
Therefore, epithelial tissue is anchored to connective tissue by a thin, non-cellular structure called the basement membrane.

Ocean floor is much more denser than the continental crust that's why the oceanic crust subduct rather than the continental crust
A.Breathing because even plants "Breathe" its just called transpiration and respiration
Answer:
Gram negative bacteria don't retain purple color as they contain thin cell wall which is composed of peptidoglycans present between inner cytoplasmic cell membrane and bacterial outer membrane.
Explanation:
They contain some characters like-
- The outer membrane is important as it protects them from antibiotics,detergents that damages the peptidoglycans of cell membrane.
- The outer membrane is composed of lipopolysaccharide that secrets lipid A component which causes toxic reaction.
- This toxic reaction creates different health hazards like high fever,increase respiratory rate,low blood pressure etc.
- Braun's lipoprotein present between outer membrane and peptidoglycans by a covalent bond.
