There are small holes in the cell wall that let nutrients, waste, and ions pass through. Those holes are called plasmodesmata. These holes have a problem: water can also be lost. But even when the plant cell loses water, the basic shape is maintained by the cell walls. So if a plant is drooping because it needs water, it can recover when water is added. So its pretty much so it can take in water.
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 cell membrane is made of carbohydrate, lipid, and protein molecules.
No, the cell membrane and protein coat are not the same thing. The cell membrane is a phospholipid bilayer that surrounds the cell, providing structure and regulating what goes in and out. A protein coat, on the other hand, is a protective layer made of proteins that surrounds some viruses.
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Cell membrane pores are made up of protein.
The cell membrane is made of carbohydrate, lipid, and protein molecules.
It is made up of protein and lipids
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.

An animal Cell membrane is made up of phospholipids (main bulk of membrane), Proteins, protein channels and Cholesterol. Protein parts main role is for structure and the protein channels allow active transport of molecules in or out of the cell. The Phospholipids however are semi permiable and so also allow some materials in and out of the cell too. Cholesterol is involved with the fluidity of the cell membrane. Hope this helps. :o)
