Usually, respiration and breathing are considered same. However, there is a great difference between respiration and breathing. Breathing: This is a constant process, that takes place constantly through out the day. This is a process of inhaling oxygen and exhaling carbon dioxide. Respiration:
Polyploidy: Polyploidy,, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis. Polyploidy is common among plants and has been, in fact, a major source of speciation in the angiosperms.
Triploid and tetraploid chromosomes are examples of polyploidy. Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (Eukaryotes) are diploid, meaning they have two sets of chromosomesâone set inherited from each parent.However, polyploidy is found in some organisms and is especially common in plants.pecies whose cells do not have nuclei, that is, Prokaryotes, may be polyploid organisms, as seen in the large bacterium Epulopicium fishelsoni [1] . Hence ploidy is defined with respect to a cell. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis.
