It has a structural function that is to maintain the structural integrity of the cell and prevent all of the intracellular material from being outside.
It has a physiologic/biochemical function also, and that is to regulate what enters and leaves the cell (it is semi permeable), and it also has receptors that react with substances and this is how messages are passed to and from cells.
a cell wall or nueclues not sure
They are surrounded by The Cell Membrane - they are also surrounded by the 'fluid' extra-Cellular Matrix.
Outer cell surface that regulates entrance and exit of molecules.
Cell membrane
In plant cells, a cell membrane and a cell wall surround the cell to aid in support and protection. In animal cells, only a cell membrane surrounds the cell and controls what substances go in and go out of the cell.
no they are not surrounded by any membrane
each body cell is surrounded by cell membrane
It hold every thing together and has the same function as a cell membrane that means, it is surrounding the cell and deciding what to let into the cell.
Every plant and animal cell is surrounded by a cell membrane. Plant cells have both a cell membrane and a cell wall because they can create there own food through photosynthesis. Animal cells have to absorb food, so they cant have a cell wall.
The cells control center, the nucleus, is surrounded by the cell membrane. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
In animal cell it is surrounded by cell membrane. In plant cell it is surrounded by cell wall.
All cells are surrounded by a plasma membrane of some kind, but depending on the cell type they can also be surrounded by additional structures. Plant cells have a cell wall to maintain hydrostatic pressure and gram-positive bacteria have a thick coating of peptidoglycans surrounding their plasma membrane.

It is for maintaining liquids in a cell which is necessary for al the cells functions
