In animals, it is the cellular membrane. In plants it is the cell wall and cell membrane.
The cell membrane is a organelles that is boundary between a cell and its environment.
The plasma membrane separates the interior of all cells from their external environment. It is a selectively permeable barrier that controls the passage of substances in and out of the cell.
The cell membrane is a semi-permeable membrane that forms a boundary between the cell and the external environment. The vacuole is the storage area within the cell.
When a cell is placed in corn syrup, water will move out of the cell through the process of osmosis, causing the cell to shrink and potentially undergo dehydration. This is because the concentration of solutes is higher outside the cell compared to inside, leading to a net movement of water out of the cell.
It depends if the cell is an animal or plant cell. If it is an animal cell then the cell membrane is the outer boundary. If it is a plant cell then the cell wall is the outer boundary.
Plasma membrane
Plasma membrane
Most of the communication between the interior and exterior of cells occurs through the cell membrane. The cell membrane regulates the passage of substances in and out of the cell through various processes such as diffusion, osmosis, and active transport. It also contains receptor proteins that allow cells to respond to signals from their environment.
When the neuron is at rest, a charge difference known as the resting membrane potential exists between the interior and exterior of the axon. This potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell compared to the outside.
The cell membrane is a organelles that is boundary between a cell and its environment.
The plasma membrane separates the interior of all cells from their external environment. It is a selectively permeable barrier that controls the passage of substances in and out of the cell.
Ribosomes are the organelles that build proteins within the cell. Without protein, the cell could not form structural units, transport any matter between the interior and exterior, or create enzymes. As a result the cell would die.

On the exterior linking the sugar backbones together.
It isn't bad. It is a boundary between the cell inside and the area around it.It isn't bad.
The cell membrane forms a boundary between the inside and outside of the cell. It is very flexible.
Outer dynamic boundary is cell membrane. Outer boundary is cell wall
