Increase in volume of mitochondria due to an influx of fluid; it occurs in hypotonic solutions due to osmotic pressure and in isotonic solutions as a result of altered permeability of the membranes of respiring mitochondria.  

Parts of a cell where aerobic production (also known as cell respiration) takes place. Specialized subcellular compartment in the muscle cell. The powerhouse of the cell, capable of producing mass quantities of ATP to fuel muscular contractions. Spherical or rod-shaped organelles, found outside the nucleus, that produce energy for cells through cellular respiration. Granular or…

The systematic movement of genes between populations of the same species, geographic race, or variety. Movement from one location to another; during development various structures migrate from a central location to their final anatomic position (e.g., the testicles are formed in the abdominal cavity and migrate into the scrotal sac).  

Slender, cylindrical filaments found in the cytoskeleton of plant and animal cells. They are composed of the protein tubulin. Linear tubular structures of higher cells, formed from tubulin dimers; essential for cell division and vesicular transport processes. Hollow, elongated tubular structure within a cell; serves a number of functions, including support of the cell and…

Small uniformly-sized spherical particles frequently labeled with radioisotopes or various reagents acting as tags or markers. Minute container suitable for implantation or injection into the body or circulatory system. Microspheres may be used for delivering medicines to certain sites or, if radioactive, to study the blood flow to an area. If microspheres are used as…

The application of microscope magnification to the study of materials that cannot be properly seen by the unaided eye. The science of the use of microscopes. Use of a microscope to view objects.  

The study of microorganisms such as fungi, bacteria, algae, archaea, and viruses. The science dealing with the structure, classification, physiology, and distribution of microorganisms, and with their technical and medical significance. The term microorganism is applied to the simple unicellular and structurally similar representatives of the plant and animal kingdoms. With few exceptions, the unicellular…

Pertaining to microbiology : the science that deals with microorganisms, including algae, bacteria, fungi, protozoa and viruses.  

An organism which cannot be observed with the naked eye; e. g. unicellular animals, lower algae, lower fungi, bacteria. A microscopic organism; applied particularly to bacteria. The word “microbe” was coined by Monsieur Sedillot, a colleague of Louis Pasteur.
