Forms a barrier between the living material inside the cell and outside environment of the cell?
The cell membrane
What acts as a barrier between the inside of the cell and the cell's environment?
Cell membrane
How does epithelial tissue do its job?
Epithelial tissues are used in multicellular organisms to protect areas of their bodies that come into contact with the external environment, so they are mostly found in skin and the gastrointestinal tract.
Comparison between epidermal tissue of plants and epithelial tissue of animals?
Epidermal tissues in plants includes several differentiated cell types. They are epidermal cells, guard cells, subsidiary cells, and epidermal hair. Many plants have waxy cuticle layer deposited on top of the epidermal cells. Epithelial tissues consist of epithelial cells which form continuous sheets that are attached to each other at many locations by tight junctions and desmosomes. Both plant epidermal tissues and animal epithelial tissues form the most numerous and largest tissues for their specific organisms. Both plant epidermal tissues and animal epithelial tissues also are very densely packed together, leaving very little intercellular space. The plant epidermal tissues functions in prevention of water loss and act as a barrier to fungi and other invaders. It also regulates gas exchange in plants and absorb water and minerals nutrients(especially in roots) The epithelial tissues not only covers the external environment of plant from the external environment but also lines the surfaces of internal organs of an organisms, unlike the plant epidermal tissues that only act as barrier between external environment and external environment.Functions of epithelial tissue includes secretion, selective absorption, protection. transcellular transport and detection of sensation. Other than that, both of the structure act mainly as protective barrier between the internal environment of living thins and the external environment.
What is the function of brondchial tubes?
The bronchial tubes serve as a passageway for air between the external environment (through the nose or mouth) and the lungs.
What is direct external environment and indirect external environment?
distinguish between direct& indirect environment
What type of tissue would be creating a waterproof barrier between the body and the environment?
Skin creates a water proof barrier between the body and environment.
How do partial pressures of gases influence the exchange of gas?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.
What are barrier between the inside of a cell and its environment?
A membrane.
What part of the cell forms a barrier between the cell and it and environment?
The barrier between the external environment and the inside of the cell is the cellular membrane, or just cell membrane. A cell wall is also present in plant cells, but substances can still enter through the cell wall. Harmful substances are stopped only when reaching the cell membrane. Some unicellular bacteria (or viruses) form an external layer outside the cell membrane, known as an envelope.
What is the barrier between the inside of a cells and its environment?
plasma membrane
What is the barrier between the inside of cells and its environment?
plasma membrane

What is the balance between the internal and external environment?
walls
What is a barrier between the inside of of a cell and it's environment?
It is the cell membrane.
What are the differences between internal and external environment?
The differences between internal and external environment is: Internal environment involve within the organization, which are the employee attitudes,new equipment,strategy,work forces. The organization has the control of these matters because it happen within the organization unless like external environment. AND for the external environment,is clearly stated with the word external itself which means outside of the organizations which effect the changes in the organization which the organization does not have the control of it. External environment are involved by the PESTLE- Politic, Economy, Social, Technology, Legal and Environment.
