Cytoplasm - Filling Fluid
Cytoplasm is the fluid that fills a cell. Scientists used to call the fluid protoplasm. Early on, they didn't know about the many different types of fluids in the cell. There is special fluid in the mitochondria, endoplasmic reticulum, Golgi apparatus, and nucleus. The only two 'plasms' left are cytoplasm (the fluid in the cell also called cytosol) and nucleoplasm (the fluid in the nucleus). Each of those fluids has a very different composition.
The cell organelles are suspended in the cytosol. You will learn that the microfilaments and microtubules set up a "skeleton" of the cell and the cytosol fills the spaces. The cytoplasm has many different molecules dissolved in solution. You'll find enzymes, fatty acids, sugars, and amino acids that are used to keep the cell working. Waste products are also dissolved before they are taken in by vacuoles or sent out of the cell.
Special Fluids in the Nucleus
Nucleoplasm has a little different composition. Nucleoplasm can only be found inside of the nucleus. It doesn't have big organelles in suspension. The nucleoplasm is the suspension fluid that holds the cell's chromatin and nucleolus. It is not always present in the nucleus. When the cell divides, the nuclear membrane dissolves and the nucleoplasm is released. After the cell nucleus has reformed, the nucleoplasm fills the space again
More than Filling
The cytosol in a cell does more than just suspend the organelles. It uses its dissolved enzymes to break down all of those larger molecules. The products can then be used by the organelles of the cell. Glucose may exist in the cytosol but the mitochondria can't use it for fuel. The cytosol has enzymes
that break glucose down into pyruvate molecules that are then sent to the mitochondria.
Answer 2 :
Cytoplasm is the watery environment inside the cell. This extracellular fluid consists of all of a cell's internal contents, and is mostly made of water. Cytoplasm includes salts, an assortment of organic molecules, including many enzymes that catalyze reactions, as well as water. The cytoplasm is seperated from the wattery extracellular fluid, which is outside, by the plasma membrane. It contains discrete membrane-enclosed structures called organelles. Each of the organelles performs a specific cellular function. They also have specialized proteins that provide an intracellular support system.
The cytoplasm is in all cells, where metabolic reactions occur. Cytoplasm can be found in eukaryotic cells, which are plant cells, and in the prokaryotic cells, which are plant cells. The cytoplasm in animal cells is much larger than that found in the plant cell. The fluid of the cytoplasm is a thick soup of proteins, carbohydrates, salts, sugars, lipids, nucleotides, and amino acids. Bacterial cytoplasm contains ribonucleic acid (RNA), on which proteins are sythesized. Cytoplasm has three main functions, energy, storage, and manufacturing. It contains other organelles which store and produce energy. The cytoplasm is also the storage place within the cell.
