What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
What do you understand by terms semi permeable?
A semi-permeable membrane is a membrane that allows certain substances to pass through while preventing others from crossing. It selectively permits the passage of molecules based on size and charge. This property is crucial in biological processes such as osmosis and filtration.
The process of allowing substances into and out of the cell is controlled by?
The process of allowing substances into and out of the cell is controlled by the cell membrane, which is selectively permeable. This means that the membrane regulates the movement of ions, molecules, and other substances across it, through processes such as diffusion, osmosis, and active transport.
What does it mean when cell membrane is selectively permeable?
The cell membrane will only allow certain molecules access. For example, glucose molecules are too large to pass through the cell membrane without undergoing endocytosis, but water molecules can easily pass through the cell membrane.
What is a selectively permeable memberane?
A selectively permeable membrane allows certain molecules or ions to pass through while blocking others based on their size, charge, or other characteristics. This feature helps regulate the movement of substances in and out of cells, maintaining internal balance and supporting essential cellular functions.
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
The plasma membrane is a semipermeable membrane. This means that it is?
selectively permeable, allowing only certain substances to pass through while blocking others. This regulation of what enters and leaves the cell helps maintain cellular homeostasis and function.

What does it mean to be "semi-permeable" and how does this property affect the movement of substances across a membrane?
Being "semi-permeable" means that a membrane allows certain substances to pass through while blocking others. This property affects the movement of substances across a membrane by regulating which molecules can enter or exit the cell. It helps maintain the cell's internal environment and allows for selective transport of essential nutrients and waste products.
The process of allowing substances into and out of the cell is controlled by?
The process of allowing substances into and out of the cell is controlled by the cell membrane, which is selectively permeable. This means that the membrane regulates the movement of ions, molecules, and other substances across it, through processes such as diffusion, osmosis, and active transport.
Is a membrane selectively permeable?
Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)
What is the role of the cell membrane in moving substance in and out of the cell?
The cell membrane is considered to be semipermeable. This means that it will let some substances through (either in or out), but others it won't. The cell membrane is considered to be 3 layers (lipid, protein, lipid) Certain proteins will help substances into the cell, but some they won't let in. Generally, smaller molecules (oxygen, water, CO2, etc.) will pass through easier than larger molecules (glucose, other sugars). Basically, the cell membrane determines what substances are allowed to pass it/out of the cell.
What does it mean when cell membrane is selectively permeable?
The cell membrane will only allow certain molecules access. For example, glucose molecules are too large to pass through the cell membrane without undergoing endocytosis, but water molecules can easily pass through the cell membrane.
What is meant by the following statement about the cell membrane The cell membrane is said to be semipermeable.?
It is very selective about what it allows to pass through.
What is a selectively permeable memberane?
A selectively permeable membrane allows certain molecules or ions to pass through while blocking others based on their size, charge, or other characteristics. This feature helps regulate the movement of substances in and out of cells, maintaining internal balance and supporting essential cellular functions.
What does it mean that the cell membrane is selectively permeable?
It means that the cell membrane allows some substances to pass through while blocking others. This property helps regulate what enters and exits the cell, maintaining the balance of molecules and ions inside.
What term means to allow some things into the membrane but not all things?
Selectively permeable, also known as semipermeable, describes a membrane that allows only certain substances to pass through while blocking others. This selective permeability helps regulate the movement of molecules in and out of a cell or organelle.
