What is the role of the plasma membrane in maintaining the internal balance of the cells?
Cell membrane is a selectively permeable lipid bilayer membrane surrounding the protoplasm. It regulates the entry and exit of substances inside and out of cell via receptors in response to the concentrations of substances inside the cell 2
What is The plasma membrane helps to maintain a cells what?
The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
Do plant and animal cells have a plasma membrane?
Yes, both plant and animal cells have a plasma membrane. The plasma membrane is a semi-permeable barrier that surrounds the cell and controls the movement of substances in and out of the cell.
Size of the plasma membrane in an animal cell?
The average is 7 nanometres in width (from outside to inside the cell).
What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
Does transported substances never physically cross the plasma membrane in endocytosis?
In endocytosis, transported substances are enclosed in vesicles formed from the plasma membrane, which do physically cross the plasma membrane. These vesicles then transport the substances into the cell.
Is plasma membrane premeable?
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances

What are the substances located in the plasma membrane?

What does the plasma membrane do in the cell?
The plasma membrane is somewhat like a filter system.It regulates the entry and exit of substances in and out of the cell.
