Do substances enter any plant or animal cell by passing through a cell membrane?

Molecules can not pass through the cell membrane, because endocytosis is important for those large molecules that can not pass through the cell membrane!!

What does cell membrane do for the animal cell?
It surround the animal cell and keeps it together. It controls the substances passing into and out of the cell.a little more simple form- protects the cell and regulates what goes in and out of the cell. just for all you noobs out there
What must a substance pass through to enter or leave a cell?
If substances did not pass through cell membranes, then all single-celled and multicellular organisms would die.
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.
In the plant cell What cell lets substances in and out?
A plant cell has a cell membrane which controls the movement of substances in and out of the cell. :D
What is the funtion of a Cell membrane?
A cell membrane's function for an animal cell is, it gives the cell its shape, strength, holds cell together, and controls what goes in and out of the cell. For a plant cell it just, holds cell together, and controls what goes in and out of the cell.
What allows certain materials to pass in and out of the cell?
A cell wall on both the plant & animal cells. a cell membrane (yes membrane is spelled M-E-M-B-R-A-N-E.) in just a plant cell. the following contribution is by Draycos a SEMIPERMEABLE membrane will allow some substances to pass and prevent other substances from passing. another name for this kind of membrane is SELECTIVELY PERMEABLE

What does the cell membrane do in an animal cell?
Regulates the passage of substances into and out of the cell.

What Controls the passage of substances into and out of a animal cell?
The semipermeable cell membrane which has two layers of phospholipids controls movement into and out of the cell membrane.
What does the cell membrane do in animal cells?
It controls what substances go in and out. Ask your science teacher for more tips on what the cell membrane does...
What do the parts of an animal cell do?
The cell membrane conrols all the substances that go in and out of the plant cell
Which structure is in both plant cells and animal cells controls the passage of substances into and out of cells?
The cell membrane is specially adapted, as it is selectively permeable.
What controls substances that enter and leave the cell?
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.
What is a cell membrane that is selectivly permeable?
A cell membrane is found on both plant and animal cells it selectively chooses what substances may enter or leave the cell. Hence the term selectively permeable. For a more advanced explanation I recommend you research protein icebergs and the different types of transport a membrane can take part in. Example active transport
