Which example is a function of the selectively permeable membrane of a cell?

Which example is a function of the selectively permeable membrane of a cell?

The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules. Movement across a selectively permeable membrane can occur actively or passively. For example, water molecules can move passively through small pores on the membrane.

What is another term for selectively permeable?

semipermeable membrane (redirected from Selectively permeable)

Which one of the following is a selectively permeable membrane?

plasma membrane

What kind of permeable is the cell membrane?


Which of the following is not an example of selectively permeable membrane?

The cell wall is the rigid hard covering of cell except for animal cells. It is the permeable structure that allows passing everything in and out of the cell. Thus, the correct answer is option B.

What do you mean by selectively permeable membrane class 9?

Answer- Plasma membrane called a selectively permeable membrane because it regulates the movement of substances from within to outside of the cell. This means that the plasma membrane allows the entry of some substances while preventing the movement of some other substance.

Which of the following is an example of impermeable membrane?

Egg shells are impermeable membranes. Everything the baby bird, snake or platypus needs is already inside and needs to say inside. Additionally, mama does not want anything else getting in, like dirt, poisons, or disease that could hurt the fetus. Another excellent example of an impermeable membrane is your skin.

What make a cell membrane selectively permeable?

Phospolipid bilayer, with some protein, is what makes the cell membrane selectively permeable. This allows smaller molecules and water molecules to go freely in and out of the cell through a process called passive transport.

How do things pass through the cell membrane?

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
