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.
Many grass species are polyploid; some species can have more than 10 sets of chromosomes. Polyploidy occurs in some animals, such as goldfish, salmon, and salamanders, but is especially common among ferns and flowering plants, including both wild and cultivated species.Many grass species are polyploid. Polyploids tend to be larger than their diploid counterparts. They have larger cells with increased volume. â¢ Polyploids tend to display semi-sterility or sterility. â¢ Polyploid plants tend to display heightened susceptibility to frost damage and higher resistance to pests and pathogens.
