Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
The protective layer that covers the surface of a plant to prevent water loss is called the cuticle.
The structure that forms a protective layer rich in glycoproteins on the surface of cells is the glycocalyx. It helps in cell-to-cell recognition, protection from mechanical stress, and acts as a barrier against pathogens.
The outer layer of roots and stems, called the epidermis, develops from the protoderm, which is one of the three primary meristems in plant growth. The protoderm gives rise to the outer protective layer of cells that covers the plant's surface.
The protective layer of cells that covers the actively growing tip of a root is called the root cap. Its function is to help guide the root through the soil and protect the delicate cells of the root tip as it pushes through the soil in search of water and nutrients.
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
Periosteum is the type of bone that covers the surface of every bone in the body. It is a dense layer of vascular connective tissue that provides nourishment and serves as a protective layer for bones.
The outer surface layer of cells in plants is called the epidermis. In animals, the outermost layer of cells is called the epithelium. Both serve as protective barriers, regulate the exchange of substances, and provide a first line of defense against pathogens.
For most cells, it is the cell membrane. Cells have a plasma membrane that is very selectively permeable i.e, will allow entry of substances that are necessary for the cell functioning. In case of an egg cell, it is surrounded by follicular cells. It provides protection from various acidic conditions. For a plant cell, the cell wall serves as a barrier.
yes the cell membrane is the protective layer around cells that's underneath the cell wall.
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.
it is the outer most layer of the leave and so covers the leave surface except at the stomata
There isn't one. Epidermis means the outer layer of skin.
