An example of a semipermeable membrane is a cell membrane. By keeping the inside of a cell at low concentration, it can keep absorbing the molecules it needs. This is used by most cells, including the roots of plants, which use osmosis to absorb the water and nutrients they need.

The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates.

: partially but not freely or wholly permeable specifically : permeable to some usually small molecules but not to other usually larger particles a semipermeable membrane.

The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. It allows hydrophobic molecules and small polar molecules diffuse through the lipid layer, but does not allow ions and large polar molecules cannot diffuse through the membrane.

Semipermeable membrane describes a membrane that allows some particles to pass through (by size), whereas the selectively permeable membrane “chooses” what passes through (size is not a factor).

Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.

What is another word for semipermeable?

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.

A semipermeable membrane is a thin membrane that will pass certain small molecules, but not others. A thin sheet of cellophane, for example, acts as a semipermeable membrane. In osmosis, the solute remains in its original side of the system; only solvent molecules move through the semipermeable membrane.

Human skin has a low permeability; that is, most foreign substances are unable to penetrate and diffuse through the skin. Skin’s outermost layer, the stratum corneum, is an effective barrier to most inorganic nanosized particles.

Although the skin is impermeable to water, it is not impermeable to all substances. Instead, the skin is selectively permeable, allowing certain fat-soluble substances to pass through the epidermis.

4. Which of the following is not used for semi-permeable membrane? Explanation: Polymethyl sulphate is not used for semi-permeable membrane. Cellulose acetate, polyamide polymer and polymethyl acrylate are used as semi-permeable membranes.

1. Natural semipermeable membrane: Vegetable membranes and animal membranes which are found just under the outer skin of the animals and plants. 2. Artificial semi permeable membrane: e.g parchment paper, cellophane and certain freshly prepared inorganic membrane.

Answer: The right answer is option D) all. Out of given biological membrane the semi permeable is all the given options including A) Fish and animal bladder, B) Egg membrane, C) Plasma membrane of cell.

Complete answer:

In the case of the isotonic solution, there was roughly an equal amount of solutes in the corn syrup/water solution than there was in the egg, so there was no net movement in or out of the egg. It stayed the same size. So, water flowed into the egg, and as a result, it grew in size.

Procedure:

1. Put your egg into a tall drinking glass.
2. Pour vinegar into the glass until the egg is covered.
3. Put the glass aside so no one drinks and/or spills it.
4. Let the egg soak overnight.
5. Rinse the vinegar and foam out with water and then cover the egg again with vinegar.
6. Wait for 6 days.

To reach equilibrium, water molecules move from the vinegar into the egg through the semi-permeable membrane. Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink.
