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 mitochondria is an organelle found in eukaryotic cells that performs cellular respiration among other things. Cellular respiration is series of chemical reactions through which glucose is converted into the energy carrier-ATP.itochondria convert organic materials into cellular energy in the form of ATP, but mitochondria also play an important role in many metabolic tasks, such as: 1  Apoptosis-programmed cell death. 2  Glutamate-mediated excitotoxic neuronal injury. 3  Cellular proliferation. 4  Regulation of the cellular redox state. 5  Heme synthesis.
