  Cytoplasm   (Site not responding. Last check: 2007-11-07)
The cytoplasm is found inside the cell membrane, surrounding the nuclear envelope and the cytoplasmic organelles.
Cytoplasm is the home of the cytoskeleton, a network of cytoplasmic filaments that are responsible for the movement of the cell and give the cell its shape.
The function of the cytoplasm and the organelles which sit in it, are critical the cell's survival.

 Cytoplasm   (Site not responding. Last check: 2007-11-07)
The cytoplasm is seperated from the wattery extracellular fluid, which is outside, by the plasma membrane.
Cytoplasm can be found in eukaryotic cells, which are plant cells, and in the prokaryotic cells, which are plant cells.
The fluid of the cytoplasm is a thick soup of proteins, carbohydrates, salts, sugars, lipids, nucleotides, and amino acids.

 Cytoplasm - Wikipedia, the free encyclopedia
The cytoplasm consists of cytosol and the cellular organelles, except the cell nucleus.
The cytoplasm plays an important role in a cell, serving as a "molecular soup" in which the organelles are suspended and held together by a fatty membrane.
The insoluble constituents of the cytoplasm are organelles (such as the mitochondria, the chloroplast, lysosomes, peroxysomes, ribosomes), several vacuoles, cytoskeletons, as well as complex cell membrane structures like the following:(e.g., endoplasmic reticulums and the Golgi apparatus).

 cytoplasm
The portion of the cytoplasm that lies outside organelles and includes other insoluble cellular components is called cytosol.
Seen through an electron microscope, the cytoplasm appears as a three-dimensional lattice of thin protein-rich strands known as the microtrabecular lattice (MTL), which serves to interconnect and support the other solid structures in the cytoplasm.
Cytoplasm is also the home of the cytoskeleton, a network of cytoplasmic filaments responsible for the movement of the cell and which gives the cell its shape.

 Cytoplasm
80% of the cytoplasm is aqueous and composed of ions and soluble, primarily organic, macromolecules.
The 20% of the cytoplasm that is not aqueous is made up of organelles, mitochondria, chloroplasts, vacuoles, the cytoskeleton, and complex membrane structures like the endoplasmic reticulum.
In a plant, the cytoplasm occupies considerably less space in cells than in animals; this is largely because of vacuoles.

The cytoplasm contains the rest of the organelles such as the endoplasmic reticulum and the mitochondria, each necessary for the cell's reproduction and survival.
The area of the cytoplasm outside of the individual organelles is called the cytosol.

 cytoplasm
However, cytoplasm is often used to refer to the jellylike matter in which the organelles are embedded (correctly termed the cytosol).
Most of the activities in the cytoplasm are chemical reactions (metabolism), for example, protein synthesis.
In many cells, the cytoplasm is made up of two parts: the ectoplasm (or plasmagel), a dense gelatinous outer layer concerned with cell movement, and the endoplasm (or plasmasol), a more fluid inner part where most of the organelles are found.
