Why does cytoplasm need to enclosed by a semi-permeable membrane?

The cytoplasm is the body of a cell. It is surrounded by the Cell membrane.
Permeable means its ability to allow particles or nutrients to pass through. It is called semi-permeable [membrane] because it only allows some particles or nutrients to pass through, not all.

What structure do all cells need?
they all need a nucleus (the brain of the cell), a cell membrane and cytoplasm.
What are the functions of the cell membrane of all organisms?
The cell membrane is semipermeable, meaning it can let some things through but not others. This membrane keeps many things out, protecting the cell, while at the same time allowing certain things through that the cell may need or need to eliminate.
Does plant cells need a cell membrane?
Yes plant cells need a cell membrane. In addition to the cell membrane they also have a cell wall. Animal cells however do not have a cell wall but merely a membrane. A cell is not able to live without a membrane as it holds the organelles and cytoplasm in place.
What is the region with in the plasma membrane and the nucleus?
The answer is ~Cytoplasm~If you need help with any other questions just email( owlcityfan37@gmail.com )
Is cytoplasm in plasma membrane?
Well some thing has to keep the cyto [cell] plasm [fluid] within the cyto [cell]. A membrane [containment] could would act as a wall covering the surface and retaining the overall viscosity on the inside surrounding the cells nucleus. Keep in mind that the membrane is still a two way perimeter letting certain things into the [cyto] and passing certain substances out, based upon the need for keeping a balance and maintaining appropriate homeostasis. the membrane responds to both active an d passive transport.

What is the need for a semi permeable membrane?
we need a semipermeable membrane for a process called osmosis...

Is water and everything else the cells need let in by the cytoplasm?
No, by the cell membrane.

cell membrane!!! not ribosomes! -wrong plant cells have cell walls and animal cells have cell membrane, it might seem right but it is wrong. Nearly all cells have a mitochondrion.^ While the answer above is correct, the real answer is Cell Membrane. So all cells have cytoplasm, AND cell membranes.
