In such cases, prolonged lack of receptivity may suggest the need to artificially inseminate or force-breed the animal. Examining vaginal smears in such cases will alleviate such concerns-certainly, if more than a very small percentage of cells are parabasals and small intermediates, breeding is a waste of time.
Mitochondria are specialized structures unique to the cells of animals, plants and fungi. They serve as batteries, powering various functions of the cell and the organism as a whole.itochondria are unlike most organelles (with an exception of plant chloroplasts) in that they have their own set of DNA and genes that encode proteins. Plant mitochondria were first observed by Friedrich Meves in 1904, as mentioned by Ernster and Schatz (Journal of Cell Biology, 1981).
The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek Î¼Î¯ÏÎ¿Ï, mitos, i.e. thread, and ÏÎ¿Î½Î´ÏÎ¯Î¿Î½, chondrion, i.e. granule or grain-like.Mitochondria range from 0.5 to 1.0 Î¼m in diameter.A considerable variation can be seen in the structure and size of this organelle.he matrix is important in the production of ATP with the aid of the ATP synthase contained in the inner membrane. The matrix contains a highly concentrated mixture of hundreds of enzymes, special mitochondrial ribosomes, tRNA, and several copies of the mitochondrial DNA genome.
