What is selectively permeable materials?
Selective permeable materials refer to substances that allow certain molecules or ions to pass through while preventing others from doing so. This property is due to their structure and composition, which includes channels, pores, or specific binding sites that only accommodate certain molecules or ions based on size, charge, or other characteristics. Examples of selectively permeable materials include cell membranes, which regulate the passage of molecules in and out of cells, and semi-permeable membranes used in filtration processes.
Why is the plasma membrane selectively permeable?
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.
What characteristic makes the cell membrane selectively permeable?
Passive and active transport. Passive transport doesn't require the cell's energy, while active transport does.
Which is an appropriate description of the arrangement of the cell membrane?
The cell membrane is a phospholipid bilayer with embedded proteins that control the movement of substances in and out of the cell. It is selectively permeable, allowing some molecules to pass through while blocking others. The membrane's structure is dynamic and can change in response to environmental conditions or cellular needs.
Animal cell membrane is filled with?
The animal cell membrane is primarily composed of a double layer of phospholipid molecules, with embedded proteins, cholesterol, and carbohydrates. This structure forms a selectively permeable barrier that regulates the movement of substances in and out of the cell.
Which the structure in plant cell are selectively permeable allowing molecules of water and small solutes to pass through but preventing the passage of large solute molecule?
only plasma membrane

Why is a plastic bag selectively permeable?
Does not allow matter to pass, but energy (light, heat, etc) is allowed to enter.

What characteristic makes the cell membrane selectively permeable?
Passive and active transport. Passive transport doesn't require the cell's energy, while active transport does.
What structure is required for osmosis?
A partially permeable membrane is required for osmosis to occur. This membrane allows the passage of solvent molecules (usually water) while preventing the passage of solute molecules.
Which is an appropriate description of the arrangement of the cell membrane?
The cell membrane is a phospholipid bilayer with embedded proteins that control the movement of substances in and out of the cell. It is selectively permeable, allowing some molecules to pass through while blocking others. The membrane's structure is dynamic and can change in response to environmental conditions or cellular needs.
Which structure is in both plant cells and animal cells controls the passage of substances into and out of cells?
The cell membrane is the structure found in both plant and animal cells that controls the passage of substances into and out of cells. It is a selectively permeable barrier that regulates the movement of molecules such as nutrients, ions, and waste products.
What cell structure controls what enters and exits the cell?
The cell membrane is specially adapted, as it is selectively permeable.
What structure allows only certain things to pass in and out of a cell?
The cell membrane. It is a semi-permeable membrane (or selectively permeable membrane) - this means that it only lets certain certain molecules or ions pass in or out of the cell. Permeability may depend on the molecule's size, solubility, properties, or chemistry.
What is the cell part where oxygen can pass?
All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.
Animal cell membrane is filled with?
The animal cell membrane is primarily composed of a double layer of phospholipid molecules, with embedded proteins, cholesterol, and carbohydrates. This structure forms a selectively permeable barrier that regulates the movement of substances in and out of the cell.
