A cell membrane is the permiable layer that surrounds a cell and keeps its organs in. It allows nutrients and fluid to pass into the cell and waste products to pass out of it. It is very similar to the way human skin works.

Which cell structure serves as a cell's boundary from its environment?
The Cell Membrane, and also the cell wall in the case of a bacteria or plant cell.In Animal cells, it is the Cell Membrane. It may also be referred to as the Plasma Membrane.I Plant cells, it is the cell wall.
What is the difference in plant cells and animal cells?
Some VERY basic differences is that plant cells have a cell wall, chloroplasts, and a larger vacuole.
Do centrioles organize the mitotic spindle in cell division?
No they do not, centrioles are the only organelles in a cell which are not synthesised during the G1 phase. During the telophase of cell division the two pairs of centrioles in each of their own centrosomes break down. Whilst a new nuclear memebrane is forming around the chromosomes a new par of centrioles is synthesised. Therefore centrioles are made during the telophase of the mitotic phase. Centrioles then divide into two pairs during the Synthesis phase. Each pair of centrioles then move to opposite poles of the nucleus during prophase.
Explain osmosis diffusion passive transport and active transport?
Osmosis is the diffusion of water molecules through a semi-permeable membrane. Diffusion is a passive transport that goes from a higher concentration area to a lower concentration area.Passive transport means that there is no energy required to move it.
What role do lipids play in the cell membrane?
Lipids are insoluable, fatty materials the cell can either use to construct membranes from or use as a source of energy in the form of fat. Cell membranes are double sheets of phospholipids. The water attracting phosphate groups coat the inside and outside of the membrane with the fatty lipid groups sandwiched between. These membranes can form small compartments inside cells known as vacoules. Some vacoules store lipids as an energy source. The best example is the yolk of an egg.
What does the cell memebrane do for the plant cell?
It is the mussle of the cell. In the mussle cell there is more of it
How does chloroplast work on a plant cell?
it help the cell memebrane
What is a rigid structure surrounding the cell memebrane?
cell wall
Is the cell memebrane selectively permeable?
Yes.
What is a cell memebrane's job?
It helps control what enters and leaves the cell.
What type of cell have a cell membrane?
All cells have a cell memebrane. Prokaryotic and eukaryotic.
Do plant cells have a cell memebrane?
Yes,they have a membrane.It is inside cell wall.
How can one cell pass the cell membrane but the other can't?
because of its selectival memebrane
Do plant cell have a cell memebrane?
Yes, plants have both cell walls (outside) and cell membranes (inside).
What does the cell memebrane do in a animal cell?
Protects cell and controls what goes in and out through passive and active transport
What is function of cell memebrane?
To control what particles go in and out of the cell, and regulates it, and is usually selectivity permeable.
What chemical binds to the muscle cell memebrane causing a temporary rush of what into the muscle cell?
Sodium ions
