Cytoplasm

Definition

noun

(Science: Cell Biology)

In eukaryotic cells, the cytoplasm is that part of the cell between the cell membrane and the nuclear envelope. It is the jelly-like substance in a cell that contains the cytosol, organelles, and inclusions, but not including the nucleus. In fact, the cytoplasm and the nucleus make up the protoplasm of a eukaryotic cell.

In prokaryotic cells that do not have a well-defined nucleus, the cytoplasm is simply everything enclosed by the cell membrane. It therefore contains the cytosol, and all the other cellular components, including the chromosome in the nucleoid region.


Supplement

The cytoplasm (of both eukaryotes and prokaryotes) is where the functions for cell expansion, growth, metabolism, and replication are carried out.


Word origin: Gk kyto-, comb. form of kýtos container, receptacle, body + Gk plásma.

Related forms: cytoplasmic (adjective).


Compare: protoplasm, cytosol.

Elastic cytoplasm film.

cytoplasm is liquid, so you cannot make it to form a membrane, unless you'd have two membranes holding the cytoplasm in between

Re: Elastic cytoplasm film.

It sounds like a black lipid membrane system is the sort of system you are looking for. However, the membranes are fairly unstable, so I doubt you could set one up that would last for months. http://en.wikipedia.org/wiki/Model_lipid_bilayer

Re: Elastic cytoplasm film.

I don't know what a "cytoplasm film" would be. A black membrane system comes to mind, in which a planar phospholipid bilayer is formed by painting the phospholipids across a small aperture in a rigid sheet separating two chambers ...

Elastic cytoplasm film.

Hi all, I'm trying to find out where I can find or how I can make an elastic cytoplasm film. It will be used as a separation between two chambers with a different (changing) air pressure, this means the film needs to be elastic to move in and outward. Who can ...
