What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
What must a substance pass through to enter or leave a cell?
If substances did not pass through cell membranes, then all single-celled and multicellular organisms would die.
What creates selective permebility of plasma membrane?
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
How do materials get into and out of the cell?
Through proteins in the membrane.
What Materials enter and leave the cell through openings in its?
Cell Membrane
What type of molecules can easily go through your cell membrane or are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
Would a polar substances such as sugars and amino acids pass through a cell membrane easily?
a substance such as sugar
Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
What particles could diffuse easily through a cell membrane sodium and oxygen?
Oxygen (O2)
What kinds of molecules pass through a cell membrane most easily?
small and hyrdophobic molecules
What molecules would easily be able to diffuse through a cell membrane without the help of a transport protein?
Water, any small molecule and lipids.
What must a substance pass through to enter or leave a cell?
If substances did not pass through cell membranes, then all single-celled and multicellular organisms would die.
How would sugar enter a cell that has a low concentration of particles get through a cell membrane and into a cell wall?
By diffusing across the protein membrane.
Which cell structure controls the movement of materials into and out of the cell?
M for membrane I would suppose.
Why is it important for the nutrients to pass through the cell membrane?
If they could not then the cell would starve.
