What else can I help you with?
What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
What are the special in cell membrane that allow materials such as water and sugar to pass through made of?
proteins
What maintains the fludity of the membrane?
The way the membrane is organized according to the fluid-mosaic-model. Besides, the temperature has to be warm enough to allow moving.
What is the role nuclear pore?
Small holes in the nuclear membrane of a cell's nucleus, which allow the transportation of water solluable materials in and out of the nucleus through the nuclear membrane.
What to substances control the movement of the materials into and out of the cell?
Some of the proteins and lipids do control movement of materials into and out of the cell.
What are the special structures in the membrane that allow materials as water and sugar to pass through made of?
Membrane transporter.
What is the abillity of a membrane to allow materials to pass through called?
permeability
What is the ability of a cell membrane to allow materials to pass through?
permeability
Which vessels allow materials to pass between the body and blood cells?
capillaries
What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
What is the ability of a cell membrane to allow materials to pass through it is called?
permeability
What is the ability of a cell membrane to allow materials to pass through called?
permeability
What is it called that all cells have that allow them to let materials in and out?
selectively permeable membrane.
What vessels exchange materials with the extra cellular fluid and the blood?
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
