What is a selectively permeable membrane quizlet?
A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport.
What are selectively permeable membranes?
Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Why is the cell membrane selectively permeable quizlet?
The cell membrane is said to be selectively permeable because it lets certain substances pass through while restricting the passage of others.
Which of the following best describes selective permeability quizlet?
Which of the following best describes selective permeability? The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
What is the selectively permeable membrane and why is it so important?
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment.
What is a selectively permeable membrane and why is it so important that the plasma?
The selectively-permeable cell membrane protects the cell. It maintains the balance in the internal environment of the cell by transporting the toxic substances outside the cell and bringing the nutrients inside the cell.
Why is it called a selectively permeable membrane?
The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids.
What is an example of selectively permeable?
A selectively-permeable membrane is a membrane that allows only some substances and molecules to pass into or leave the cell. An example of a selectively-permeable membrane is the cell membrane. It allows the passage of only certain types of molecules through diffusion and occasionally by facilitated diffusion.
Why is the cell membrane selectively permeable?
Why is a selectively permeable membrane so important to living things quizlet?
Why is a selectively permeable membrane so important to living things? A) It allows cells to attach to adjacent tissues. B) It provides a good barrier between the inside and outside of the cell.
Which of the following statements most accurately describes a selectively permeable membrane quizlet?
Which of the following most accurately describes selective permeability? Only certain molecules can cross a cell membrane. Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Which best describes a selectively permeable plasma membrane?
Which best describes a selectively permeable plasma membrane? only certain substances can pass through the membrane. What will happen when a cell is placed in a solution with a high salt concentration?
