What else can I help you with?
What takes materials in and out of a cell?
The plasma member is a selectively permeable membrane which allows the entry and exit of substances in and out of the cell through the process of diffusion.
Which layer controls selective permeability?
The cell membrane controls selective permeability. Larger substances can enter the cell through endocytosis and exit through exocytosis.
What type of system would allow light to enter and exit but would keep any additional atoms out?
A closed system does not let any matter enter or exit, and no energy enters or exits the system.
What is a voltage-gated membrane channel?
Voltage-gated channels are proteins in the cell membrane which open when stimulated by a voltage (an electrical signal). The voltage causes the channel to open, thereby allowing the entry or exit of whatever substance the channel relates to. An example of this the the voltage-gated sodium channels on neurons. When an action potential (a voltage), passes over the cell, it open these channels and allows sodium to enter the cell.
Is it true the tiny holes through which gases enter and exit leaves are called chloroplasts?
They are called stomatas. These are bound by guard cells.
Why do materials enter and exit the cell?
To get to the other side
What cell structure is responsible for regulating the materials that enter and exit the cell?
cell membrane
Which part of a allows certain materials to enter the cell and other materials to exit the cell?
This part of the cell is refferred to as the cell 'membrane'
What does the Vacoule do for the animal cell?
The function of the vacuole is for transporting & storing materials inside the cell. It allows materials to enter & exit the cell.
How do materials enter and exit a cell and keep the necessary cytoplasm within the cell membrane?
penis
What of a cell allows material to enter and exit the cell?
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
What allows certain materials to enter and exit the plant cell?
The cell membrane of a plant cell allows certain materials to enter and exit through processes like diffusion, osmosis, and active transport. These processes help maintain the balance of nutrients and waste products within the cell.
What in a cell membrane allow materials to enter and exit the cell?
Glycoproteins form channels which sustrates and larger molecules can pass through.
Is the process exocytosis materials that are taken into a cell?
No, exocytosis is actually the process by which materials are moved out of a cell. It involves the vesicle in which the materials are contained fusing with the cell membrane and releasing the contents outside the cell.
How does material enter and leave a cell?
Materials can exit the cell using exocitosis. Endocitosis is when cells enter the cell by the cell forcing the material to enter. Osmosis and diffusion are also ways that materials can enter/exit the cell. Remember, the cell membrane is made up of protein channels and fat layers!
How substance are able to enter and exit a cell?
osmosis
What is the name of the fluid phospholipid bilayer which determines what materials enter and exit the cell?
That is the name. Unless you have another name in mind. Sometimes it is called the fluid mosaic model or the cell membrane.
