The term plasm can be used as a suffix or prefix. Related terms include plasmo- , -plasmic, -plast, and -plasty. Suffix (-plasm) Examples: Alloplasm (allo - plasm) - differentiated cytoplasm that forms specialized structures like cilia and flagella as well as other similar structures. Axoplasm (axo - plasm) - the cytoplasm of a nerve cell axon. Cytoplasm (cyto - plasm) - the contents of a cell that surrounds the nucleus. This includes the cytosol and organelles other than the nucleus. Deutoplasm (deuto - plasm) - the substance in a cell that serves as a nutrition source, commonly refers to yolk in an egg. Ectoplasm (ecto - plasm) - the outer portion of the cytoplasm in some cells. This layer has a clear, gel-like appearance as seen in amoebas. Endoplasm (endo - plasm) - the inner portion of the cytoplasm in some cells. This layer is more fluid than the ectoplasm layer as seen in amoebas. Germplasm (germ - plasm) - the sum total of the genetic material of a particular related group of organisms or species. Such material is usually collected for breeding or conservation purposes. Hyaloplasm (hyalo - plasm) - synonymous with the cell's cytosol, the fluid part of the cytoplasm that doesn't include the organelles of the cell. Myoplasm (myo - plasm) - the portion of muscle cells that contracts. Neoplasm (neo - plasm) - abnormal, uncontrolled growth of new tissue as in a cancer cell. Nucleoplasm (nucleo - plasm) - gel-like substance in the nucleus of plant and animal cells that is enclosed by the nuclear envelope and surrounds the nucleolus and chromatin. Periplasm (peri - plasm) - in some archaea and bacteria, the area between the outer portion of the cell membrane and the inner cytoplasmic membrane. Piroplasm (piro - plasm) - the piroplasms are parasitic protozoans that can infect a variety of animals like cows and sheep. Protoplasm (proto - plasm) - the cytoplasm and nucleoplasm contents of a cell. It excludes the deutoplasm. Sarcoplasm (sarco - plasm) - the cytoplasm in skeletal muscle fibers. Prefixes (plasm-) and (plasmo-) Examples: Plasma Membrane (plasma) - membrane that surrounds the cytoplasm and nucleus of cells. Plasmodesmata (plasmo - desmata) - channels between plant cell walls that allow molecular signals to pass between individual plant cells. Plasmodium (plasmo - dium) - parasitic organisms that can infect humans. For example, Plasmodium malariae causes malaria in people. Plasmolysis (plasmo - lysis) - shrinkage that occurs in the cell cytoplasm due to osmosis. Suffix (-plasty) Amphiplasty (amphi -plasty) - repairing and reconstructing chromosomes in the cell's nucleolus. Angioplasty (angio - plasty) - medical procedure done to open narrowed arteries and veins, particularly in the heart. Aortoplasty (aorto - plasty) - medical procedure that repairs a damaged aorta. Autoplasty (auto - plasty) - surgical removal of tissue from one site that is used to repair damaged tissue in another site. An example of this is a skin graft. Bronchoplasty (broncho - plasty) - surgical repair of the bronchi, the two airways that branch off of the trachea and lead to the lungs. Cranioplasty (cranio - plasty) - surgical repair of the cranium to correct an imperfection, particularly in the case of a cranial deformity. Facioplasty (facio - plasty) - corrective surgical repair of the face, most often in the case of plastic or reconstructive surgery. Heteroplasty (hetero - plasty) - surgical transplantation of tissue from one individual or species into another. Rhinoplasty (rhino - plasty) - surgical procedure performed on the nose. Thermoplasty (thermo - plasty) - the use of heat to treat the effects and symptoms of asthma by softening the airway walls. Tympanoplasty (tympano - plasty) - surgical repair of the eardrum or bones of the middle ear. Zooplasty (zoo - plasty) - a surgical procedure that transplants living animal tissue to a human. Key Takeaways The common affix, plasm, refers to the substance that forms living cells.Plasm can be used as both a prefix or suffix in biological terms and words.Other related suffixes include -plast and -plasty along with the prefix plasmo-.Understanding biological prefixes and suffixes like plasm can help us to better understand complex biological concepts.
