What separates the internal environment of the body from the external environment?
The cell membrane separates the internal environment of the body from the external environment. It acts as a physical barrier that controls the passage of substances in and out of the cell, maintaining the cell's internal balance.
What cell organelles is made mostly of fats and proteins and controls substances moving in and out of the cell?
The cell membrane is made mostly of fats and proteins, and it controls the movement of substances in and out of the cell by acting as a selectively permeable barrier. It regulates the passage of ions, molecules, and other substances to maintain the internal environment of the cell.
What would happen if the membrane were completely made of polar substance?
The cell would be unable to maintain a stable internal environment.
Keeps cell contents separate from external environment?
A cell membrane acts as a barrier that separates the internal environment of a cell from its external environment. This selective boundary allows the cell to control the movement of molecules in and out of the cell, maintaining cellular homeostasis and protecting the cell's internal components.
What head of the phospholipids can interact with the internal environment of the cell?
The polar head of phospholipids, which consists of a phosphate group and a glycerol molecule, can interact with the internal environment of the cell. This head is hydrophilic, or water-loving, allowing it to interact with the aqueous cytoplasm inside the cell.
What is the fluid link between the external and internal environment?
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
What does the cell memberance do?
The cell membrane acts as a barrier between the extracellular fluid (ECF) and the intracellular fluid (ICF) allowing the cell to selectively control its internal environment so that it can carry out complicated biochemical reactions in a stable environment.
What system maintains the internal fluid environment by acting as an intermediary between the blood in the capillaries and tissue cell?
Lymphatic system
What separates the internal environment of the body from the external environment?
The cell membrane separates the internal environment of the body from the external environment. It acts as a physical barrier that controls the passage of substances in and out of the cell, maintaining the cell's internal balance.
Which cell part is the internal fluid found in all cell?
Cytoplasm.
What is the semifluid internal environment of the cell?
Cytoplasm
What cell organelles is made mostly of fats and proteins and controls substances moving in and out of the cell?
The cell membrane is made mostly of fats and proteins, and it controls the movement of substances in and out of the cell by acting as a selectively permeable barrier. It regulates the passage of ions, molecules, and other substances to maintain the internal environment of the cell.
Allows communication between the internal and external cell environment?
The cell membrane allows communication between the internal and external cell environment. This is due to is selective permeable nature of the membrane.
The area around a cell has a high concentration of sodium ions. as a result the cell membrane expands and bursts. which problem was the cell most likely having?
The cell is unable to maintain a stable internal environment
What happen to cell if external environment has greater solute than internal environment of cell?
Water will leave the cell by facilitated diffusion and the cell will shrink and die.
What is the fluid substance that fills the cell?
"cytoplasm" (which is mostly water)
What allows communication between the internal and external cell environment?
cell(plasma) membrane
