What are the two parts of the cytoplasm?
The cytoplasm can be divided into two primary parts: the endoplasm ( endo -,- plasm) and ectoplasm ( ecto -,-plasm). The endoplasm is the central area of the cytoplasm that contains the organelles. The ectoplasm is the more gel-like peripheral portion of the cytoplasm of a cell.
What is the structure that separates the cytoplasm from the extracellular fluid?
The cell membrane or plasma membrane is the structure that keeps cytoplasm from spilling out of a cell. This membrane is composed of phospholipids, which form a lipid bilayer that separates the contents of a cell from the extracellular fluid. The lipid bilayer is semi-permeable, meaning that only certain molecules are able to diffuse across the membrane to enter or exit the cell. Extracellular fluid, proteins, lipids, and other molecules may be added to a cell's cytoplasm by endocytosis. In this process, molecules and extracellular fluid are internalized as the membrane turns inward forming a vesicle. The vesicle encloses the fluid and molecules and buds off from the cell membrane forming an endosome. The endosome moves within the cell to deliver its contents to their appropriate destinations. Substances are removed from the cytoplasm by exocytosis. In this process, vesicles budding from Golgi bodies fuse with the cell membrane expelling their contents from the cell. The cell membrane also provides structural support for a cell by serving as a stable platform for the attachment of the cytoskeleton and cell wall (in plants).

What is the cytoplasm in a cell?

What is Cytoplasm? The fluid that fills up the cells is referred to as the cytoplasm. It encompasses the cytosol with filaments, ions, proteins, and macromolecular structures and also other organelles suspended in the cytosol. But new research suggests that the traditional definition of cytoplasm is no longer valid.
What does cytoplasm mean in narration?
Narration. Cytoplasm's a funny term. So what does "cyto" mean? "Cyto" means "cell", "plasm" means "stuff", so it's "cell stuff". So think about a cell as a big water balloon, and the water balloon has little pieces of fruit floating around in it. And the cytoplasm is the water in the water balloon, and it's a little bit thicker than water, ...

It is often referred to as cytosol, meaning "substance of the cell.".
How to see the large picture of a cytoplasm analogy of a restaurant?
In order to see the large picture of a cytoplasm analogy of a restaurant it is best to represent the entire cell through an analogy. The entire cell represents the entire restaurant, as it requires many different parts inside to function, just as cells have organelles for specific functions.
What is the function of the cytoplasm in cell division?
Cytoplasm is also a means of transportation for genetic material in cell division. It is a buffer to protect the genetic material of the cell and keep the organelles from damage when they move and collide with each other. If a cell would be without cytoplasm it could not retain its shape and would be deflated and flat.

Cytoplasm contains proteins that are 20 to 25 percent soluble, and this includes enzymes. Carbohydrates, lipids and inorganic salts are particles in cytoplasm.
Overview
In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and is usually colorless.
History
The term was introduced by Rudolf von Kölliker in 1863, originally as a synonym for protoplasm, but later it has come to mean the cell substance and organelles outside the nucleus.
There has been certain disagreement on the definition of cytoplasm, as some authors prefer to exclude from it some organelles, especially the vacuoles and sometimes the plastids.
Physical nature
It remains uncertain how the various components of the cytoplasm interact to allow movement of organelles while maintaining the cell's structure. The flow of cytoplasmic components plays an important role in many cellular functions which are dependent on the permeability of the cytoplasm. An example of such function is cell signalling, a process which is dependent on the manner in which signaling molecules are allowed to diffuse across the cell. While small signalin…
