The outermost layer of animal cells is the cell membrane (also known as the plasma membrane). The outermost layer of plant cells is the cell wall.
The cell membrane allows the movement of nutrients and wastes into and out of the cell either through passive transport (no energy required) or active transport (energy required). This ensures that the environment inside the cell remains relatively constant (this is called homeostasis).Both animal cells and plant cells have cell membranes but the cell membrane in plant cells is covered by the cell wall.
The cell wall provides structural support and rigidity to plant cells. It also maintains the shape of the plant cell.

Do all cells have a cell membrane?
All cells need a membrane. The membrane helps with keeping in all the fluids and organelles plus it takes in and sends out important things. Plant cells and bacteria have cell walls which give an extra layer of protection.
Identify two of the three assumptions in the Cell Theory?
1. Cells are the basic unit of structure in all living things.2. Cells carry on all life processes.even though you only said two...3. Cells are produced by other living cells.
Are most living things made up of cells?
Yes, all living things are made up of cells and only living things.
Cells are alive but not all living cells are organisms?
All living things are organisms. There is no such thing as a living cell that is not an organism.
What are the three parts of the cells theory?
The cell theory states that... 1. All living things are composed of cells. 2. Cells are the basic units of structure and functions in living things. 3. All cells are produced from other cells.
What is the outermost component of all cells?
The outermost living part of a cell is the cell membrane. The cell membrane regulates what comes into the cell and what goes out of the cell. It is composed of a double layer of phospholipids and proteins.
What are the main chemical in the layer that surrounds all living cells?
water
What is the structure of a plasma membrane and what is the role of their hydrophilic heads?
That is the structure of plasma membrane adjectent or near the secondary cell wall in a cells. It's a living outermost boundary of all the cells.
What are the three roles of epidermis in plants?
The outermost layer of cells is called the epidermis.The epidermis protects all the part of the plant from water loss,mechanical support and invasion of parasitic fungi.As it is a protective tissue it is a continuous layer without any intercellular space
What is the outermost toughest portion of the hair called?
the cell wall is the outermost part of the human skin and also the outermost layer of all plants its called the epidermous
The outer living limit of a cell called?
Some cells have glycocalyces and this then would be the outermost part of the cell for them but all cells must have a plasma membrane and therefore I think this would be the best answer to the question.
Are plasma membrane outermost component of all cells?
No. Some secrete a covering.
What are all the names of the earths layers?
Going from outermost layer to innermost layer, the order is as follows: Crust Mantle Core Inner Core
What are all the layers of the earths name?
Going from outermost layer to innermost layer, the order is as follows: Crust Mantle Core Inner Core
All living things are composed of cells?
Yes all living things are composed of cells.
What is the basis of all living cells?
Protien is the basis of all living cells.
What is earth's outermost layer?
The crust, the portion that contains all human land habitation and all surface features.
