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 is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
Which is better able to feed all of the cytoplasm of the cell the cell membrane of a cell that has high mass or the cell membrane of the cell that has low mass?
The cell membrane of a cell with low mass would be better able to feed all the cytoplasm of the cell. This is because a thinner membrane would allow for more efficient transport of nutrients and waste products in and out of the cell.
Is a cell membrane invironment?
The cell membrane is somewhat of an environment.. cell membranes have many proteins inside them.. the proteins regulate the cell structure, allow cell-cell interaction, and allow passage of materials through the membrane. There also steroids in the membrane that regulate its shape.. and there are also various sugars / glycoproteins in the membrane. Also, one important thing to realize is that the inside of the cell membrane is NON polar.. the outside is polar however.

What supports the cell and allow parts to move?
cell membrane

Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
Why is a cell membrane is very thin?
To allow necessary chemicals in and out of the cell.
A cell membrane is very specific about what it allow across. how does this help a cell?
The cell works better…

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 cell membrane used for in the plant cell?
The Cell membrane on a plant cell is used to allow some substances into the cell (for nourishment) while keeping other (harmful or unwanted) substances out.
How does a cell allow small molecules enter and exit?
"The cell membrane has openings in it." (PLATO) (:
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane
Which part of an animal cell lets food water and oxygen pass in and out?
The cell membrane, which is a structure surrounding the cell, controls the passage of nutrients, water, and oxygen in and out of the cell. It acts as a selective barrier, allowing specific molecules to pass through via processes like diffusion or active transport.
