15 3 Membrane Transport With Selective Permeability Biology Libretexts

The structure of the nucleus in a cell suggests that one of its chief purposes is to house and pass on DNA.

. The statement the cell membrane regulates the transport of specific substances into and out of the cell BEST describes the selective permeability of the cell membrane Option A. Active transport processes require the cell to expend energy to move the materials while passive transport can be done without using cellular energy. It is non-permeable to substances outside the cell B.

The cell membrane is a semi-permeable barrier because some substances can diffuse across the lipid bilayer while other substances cannot. A selectively permeable cell membrane is one that allows certain molecules or ions to pass through it by means of active or passive transport. Which BEST describes the plasma membrane of all living things.

Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. Only certain substances can pass through the membrane. It is selectively permeable to certain substances 2 See answers Advertisement Brainly User Answer.

Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to. 14 Which statement best explains what selectively permeable means.
