What term describes a cell membrane's ability to let substances through?
Selective permeability is the term that describes a cell membrane's ability to allow certain substances to pass through while blocking others. This is essential for maintaining cellular function and regulating the internal environment of the cell.
How does the plasma membrane controls what goes into and comes out of a cell?
The plasma membrane uses selective permeability, by which a membrane allows some substances into the cells while keeping others out. Picture a butterfly net, the holes in the allow knats and other bugs to pass through, while capturing others.
Does a permeable membrane will let substances pass through it?
Yes, a permeable membrane allows certain substances to pass through while blocking others based on their size and chemical properties. It enables the selective transport of molecules, ions, or particles across a barrier, such as in biological systems or in water filtration processes.
Why is the plasma membrane called the semipermeable membrane?
The plasma membrane is called the semipermeable membrane because it allows certain substances to pass through while restricting the passage of others. It is selectively permeable, meaning it controls the movement of substances in and out of the cell to maintain internal balance and regulate cellular processes.
Which part of a cell allows substances to pass through it?
The cell membrane, specifically its lipid bilayer, regulates the passage of substances into and out of the cell through a process called selective permeability. Various proteins embedded in the membrane also assist in facilitating the movement of specific molecules across the membrane.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others
What characteristics of cell membrane allows for some substances to pass through but not others?
wwww
When some molecules go through a membrane faster than others the membrane is what?
The membrane is said to be selectively permeable or semipermeable when some molecules can pass through it faster than others. This property allows the membrane to regulate the passage of specific substances.
A membrane that allows some substances to pass through while excluding others would be called?
selectively permeable
Does it mean for a cell membrane to be selectively permeable?
it allows some substances to pass through but blocks the passage of others.
What lets substances like food and oxygen diffuse into body cells?
The semi-permeable membrane in cells. Allows some substances to go through and not others.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
The cell membrane is composed of a phospholipid bilayer that is selectively permeable, allowing only certain substances to pass through. The presence of proteins, such as channels and carriers, also help regulate the movement of specific molecules across the membrane. Additionally, the membrane's fluidity and structure play a role in facilitating or hindering the diffusion of substances.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.
What allows some materials to pass through it but keeps other materials out?
A selectively permeable membrane allows only certain molecules or substances to pass through, based on their size, charge, or other properties. This membrane acts as a barrier that can control the passage of specific substances while blocking others.
What is the part of the cell that materials pass through?
Materials pass through the cell membrane, which acts as a barrier between the cell's interior and the external environment. The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.
Some things can pass through it while others cannot is called a what?
A semi-permeable membrane.
