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.
Diploid cells have twice the amount of chromosomes as haploid cells. Ploidy is the number of sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Somatic cells, tissues and individuals can be described according to the number of sets present: monoploid, diploid, triploid, tetraploid, pentaploid, hexaploid, heptaploid or septaploid, etc. The generic term polyploid is used to describe cells with three or more chromosome sets. Humans are diploid organisms, carrying two complete sets of chromosomes: one set
