Cytoplasm is the semifluid substance of a cell that contains all of the organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. It is the site of energy production, lipid and protein synthesis, digestion, and cell shape and support.

Cytoplasm refers to the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the nucleus. Eukaryotes have elaborate mechanisms for maintaining...
The physical nature of the cytoplasm is variable. Sometimes, there is quick diffusion across the cell, making the cytoplasm resemble a colloidal solution. At other times, it appears to take on the properties of a gel-like or glass-like substance. It is said to have the properties of viscous as well as elastic materials capable of deforming slowly ...
The basic shape of the cell is provided by its cytoskeleton formed primarily by three types of polymers actin filaments, microtubules and intermediate filaments. Actin filaments or microfilaments are 7 nm in width and are made of double stranded polymers of F-actin. These filaments are associated with a number of other proteins that help in filame...
Similar to the previous image, chromosomes are stained blue and microtubules are green. Tiny red dots are kinetochores.
Intermediate filaments are larger than microfilaments but smaller than microtubules and are formed by a group of proteins that share structural features. Though they are not involved in cell motility, they are important for cells to come together as tissues and to remain anchored to the extracellular matrix.
Most eukaryotic cells have a number of organelles that provide compartments within the cytoplasm for specialized microenvironments. For instance, lysosomes contain a number of hydrolases in an acidic environment that is ideal for their enzymatic activity. These hydrolases are actively transported into the lysosome after being synthesized in the cyt...
Each of these components affects the functioning of the cytoplasm in different ways, making it a dynamic region that plays a role in, and is influenced by the cells overall metabolic activity. The cytoplasm is the site for most of the enzymatic reactions and metabolic activity of the cell. Cellular respiration begins in the cytoplasm with anaerobic...
Movement within the cytoplasm also occurs in bulk, through the directed movement of cytosol around the nucleus or vacuole. This is particularly important in large single celled organisms such as some species of green algae, which can be nearly 10 cm in length. Cytoplasmic streaming is also important for positioning chloroplasts close to the plasma ...
The cytoplasm plays hosts to two organelles that contain their own genomes the chloroplast and mitochondria. These organelles are inherited directly from the mother through the oocyte and therefore constitute genes that are inherited outside the nucleus. These organelles replicate independent of the nucleus and respond to the needs of the cell. Cy...

Cytoplasm is the fluid that fills the cell and contains various components such as cytosol, organelles, proteins and ions. It has different physical properties and functions depending on the cell type and metabolic state.

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.
Cytoplasm is the fluid part of the cell that contains organelles and other molecules. It is mainly composed of water, salts, and proteins, and has a framework of protein scaffolds called the cytoskeleton.
