It is called the cell membrane. This is in Plant and animal cells, although the plant cell has the cellulose wall as well. The cell membrane is semi permeable. Water molecules can pass easily through it through a process call osmosis (the diffusion of water molecules).

Structure regulates the transport in and out of the cell?
The golgi bodies regulate the transport of materials in and out of the cell.
One of the most important functions of the cell membrane is to?
The Cell Membrane protects the cell and regulates what substances enter and leave it. It is like the "gate keeper"
What maintains a chemical balance within a cell by regulating the materials that enter and leave the cell?
The Plasma membrane regulates what enters and exits the cell.
What is a semi-permeable membrane that forms a boundary between the cell and the external environment?
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.
What is the cellular structure that separates the cytoplasm from the external environment?
The Cell Membrane separates the cell from its environment and prevents its contents from mixing with the outside solution.
External boundary of cell; regulates materials into and out of the cell?
Cell Membrane
What is the external boundary of cell that regulates flow of materials into and out of the cell?

What regulates the flow of materials to and from the cell?
Plasma membrane
What provides the external boundary for the material inside the cell?
cell membrane
What confines cell contents and regulates entry and exit of materials?
the cell membrane
What is the generator of the cell?
Plasma Membrane- External boundary of the cell- Confines cell contents; regulates entry and exit of materials Lysosomes- Scattered in cytoplasm- Digest ingested materials and worn-out organelles Mitochondrion- Scattered throughout the cell- Control release of energy from food; from ATP Microvilli- Projections of the plasma membrane- Increase the membrane surface area Golgi apparatus- Near the nucleus ( in the cytoplasm )- Packages proteins to be incorporated into the plasma membrane or lysosomes or exported from the cell
Which organelle is the boundary that regulates what comes in and out of the cells?
The cell membrane in animal cells. The cell wall in plant cells.
Regulates the transport of materials in and out of the cell?
cell membrane!! this is the correct answer to number 20... :D
What is the function of the cell selectively permeable plasma membrane?
it regulates what materials enter and leave the cell
What regulates a passage of materials between the cell and its environment?
cell membrane aka plasma membrane
What is responsible for maintaining the integrity of the cell?
The cell membrane is responsible for maintaining the integrity of the cell. It regulates the movement of materials in and out of the cell.
