What is a selective barrier regulating the passage of materials into and out of the cell?

In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''.
While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.

What is A waxy barrier in the plant root?
A waxy barrier in plant roots typically refers to the presence of a specialized layer of cells or substances that have a waxy or hydrophobic (water-repellent) nature. This waxy layer is often referred to as the "Casparian strip" and is found in the endodermis, a tissue layer in the root that surrounds the vascular cylinder. The main function of the waxy barrier, or Casparian strip, is to regulate the movement of water and nutrients into the plant through the roots. It acts as a selective barrier that prevents the passive movement of water and dissolved substances between cells, forcing them to pass through the cell membranes and into the cytoplasm before entering the vascular system. This barrier is crucial for maintaining proper nutrient uptake and preventing harmful substances from entering the plant. It ensures that the plant has control over what enters its vascular system, allowing it to selectively absorb beneficial nutrients while excluding potentially harmful elements. In essence, the waxy barrier in plant roots helps maintain the plant's health by regulating the passage of water and nutrients, ensuring a controlled and efficient uptake process.
Absorption involves the passage of materials into and out of what organ?
In and out of the bloodstream. I hope this helps.

What is a selective barrier that regulats the passage of material into and out of the cell?
The plasma membrane
How is lipids suited to the function of the membrane?
It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell
Why is it important that the root of endodermis permits only one way passage of materials?
Rate This Answer0 CommentsThe root endodermis permits only a one way passage of materials because the root doesn't want certain things entering. It's called selective permeability.
What is fluid attenuation?
It means regulating the passage of fluids.
The blood-brain barrier is effective against the passage of?
The blood-brain barrier is effective against the passage of ? Metabolic waste such as urea
What does Selective permeability do?
It allows the passage for certain substances.
The blood brain barrier is effective against the passage of?

How are lipids suited to the functions of the membrane?
the outer boundary of the cell. It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell.
