cells need a boundary because they need to keep out stuff that will harm the cell like viruses
The cell structure that is located in the external boundaries of the cell is the cell membrane. The cell membrane is a semipermeable membrane composed of lipids and proteins that surrounds the cell, providing a barrier between the cell's interior and its external environment.
Plant cells have more clearly defined boundaries due to their rigid cell walls made of cellulose. Animal cells have a flexible cell membrane but lack a rigid cell wall, making their boundaries less distinct in comparison.
Cell boundaries refer to the structures that define and enclose a cell, separating its internal environment from the external surroundings. In most cells, the primary boundary is the plasma membrane, a phospholipid bilayer that regulates the movement of substances in and out of the cell. In plant cells, an additional rigid cell wall provides extra support and protection. Together, these boundaries play crucial roles in maintaining homeostasis and facilitating communication between the cell and its environment.
Cells have very well definted boundaries. For animal cells, it is the cell membrane, and for plant cells it is the cell wall.
Prokaryotes have cell boundaries like eukaryotes. It has a cell membrane and a cell wall. There are two types of cell walls: Gram + or Gram-. The exterior of the cell usually has glycocalyx, flagellum, fimbriae, and pili. The glycocalyx can be sticky (a capsule) or loose (a slime layer). The flagellum look like whips and can help move the cell. The fimbriae look like short hairs and allow the cell to attach. The pili are longer than the fimbriae and shorter than the flagella. These allow the transfer of DNA from the cell to another cell.
yes. they are the outer most boundaries of any cell

The structure of cells that provide boundaries is called the cell membrane. The cell membrane is a semi-permeable barrier that surrounds the cell, regulating the movement of substances in and out of the cell. It is composed of a lipid bilayer with embedded proteins.

The cell membrane surrounds the cytoplasm of a cell and defines the boundaries of the cell.

The receiving department of an animal cell is called the plasma membrane, while in a plant cell it is called the cell wall. These structures act as boundaries that regulate the passage of molecules in and out of the cell.

1.It provide shape to the cell. 2.It protect cell membrane and cell content against machinical injuries. 3.Helps in movement of material in and out of the cell. 4.It provide individuality to cell by seperating a cell from other. 5.it helps in keeping the cell component at their place.
All organelles in cells are suspended in the cytoplasm (think - jello) but where they are is not really defined. However, if this was a test question, I'd write within the boundaries of the Cell Membrane and cytoplasm.
In cells without a cell wall, the outside boundary that separates the cell from its environment is formed by the cell membrane or plasma membrane. This phospholipid bilayer regulates the passage of molecules in and out of the cell, allowing for selective permeability.
