What is the external boundary of cell which regulates flow of materials into and out of the cell?
It is called the cell membrane. This is in Plant and animal cells, although the plant cell has the cellulose wall as well. The cell membrane is semi permeable. Water molecules can pass easily through it through a process call osmosis (the diffusion of water molecules).
What cell structure that allows cummunication between internal and external cell environment?
The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
Why do plant cells have a thick wall?
Plant cells have a thick cell wall made of cellulose to provide structure and support to the cell, protect it from mechanical damage, and help regulate the flow of nutrients and water in and out of the cell.
What is the function of xylem cell?
Xylem is a type of cell that distributes water throughout a plant. They have specialized cells that help water flow up a plant, to get where it is needed.
What is the purpose of the plant Cell wall in limiting osmotic flow into the Cell?
The plant cell wall provides structural support and protection, while also acting as a barrier that helps regulate the movement of water and solutes into and out of the cell. This helps prevent excessive swelling and bursting of the cell due to osmotic pressure differences between the cell and its surroundings.
What is the external boundary of cell that regulates flow of materials into and out of the cell?
Plasma Membrane
What is the difference between internal and external flow?
About of Blood's flow:A fluid flow is classified as being internal or external, depending on whether the fluid is forced to flow in a confined channel or over a surface. The flow of an unbounded fluid over a surface such as a plate, a wire, or a pipe is external flow. The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. The flow of liquids in a duct is called open-channel flow if the duct is only partially filled with the liquid and there is an free surface, e.g. the flows of water in rivers and irrigation ditches.
Why liquid is fluid?
A fluid is a substance, such as a liquid or gas, that can flow, has no fixed shape, and offers little resistance to an external stress.
Can a fluid flow?
Yes, fluids can flow. Fluid flow refers to the movement of liquids or gases through channels or containers under the influence of external forces like pressure or gravity. Fluid dynamics is a branch of physics that studies how fluids flow and interact with their surroundings.
What is a thermal conductor?
A substance / system that conducts heat to / from a surface, with resorting to (external) fluid flow.

Electrons in a galvanic cell normally flow?
A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.
What surrounds a plant cell and protects it?
The thin structure that surrounds the cytoplasm of a cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
What kind of muscle cell contract?
Smooth muscle cells contract in response to fluid flow.
Is every cell enclosed by a membrane?
Plant cells are enclosed by a cell membrane and cell wall. The cell wall is a rigid structure made up of cellulose and the cell membrane is a semipermeable membrane made up of protein and fat.
What is the importance of makes the plant cells turgid?
If it's a plant cell it needs good, fully-functioning palisade cells to let water flow in and out. A plant cell needs to be turgid so that the plant have a support and structure.
