They are called porins and help in the transfer of materials in and out of the cell.
the answer is the cell membrane
yes
yes
Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane. I have made a link below to a diagram of the cell membrane to show some of these structures.
the outer membrane
They are not holes.They are membrane proteins.
The cell membrane contains protein channels and transporters that regulate the movement of materials in and out of the cell. These channels and transporters control the passage of specific substances into and out of the cell. The cell membrane itself does not have "tiny holes" but rather selective protein structures that facilitate the transport of molecules.
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.
the outer membrane
I'm full of holes, Flexible, and thin. I control what get out As well as what comes in. The answer is... cell membrane
There are two possible answers. One would be the rough endoplasmic reticulum, because it has many holes, and 'tubes'. The other answer would be the cell membrane, because things get inside membranes because there are holes. the chloryphyl The nucleus The "holes" you are referring to are the "pores". The nucleus is the control center of the cell and contains the cells deoxyribonucleic acid (DNA)
