Parthenogenesis When development of organism takes place without fertilization, the process is called as parthenogenesis. Parthenogenesis is of two types viz. 1.       Natural 2.       Artificial Natural parthenogenesis: ·          Eggs that develop without fertilization naturally, the process is called as natural parthenogenesis. ·          It is commonly seen in Aphids, Phyllopods and Rotifers at sometimes of the years not always ·          Whereas in case of bees and wasps males are always produced from unfertilized egg. Thus, males are always haploid and females are diploid because females are produced from fertilized egg. ·          In some species such as Tenthredinidae, reproduction is alays parthenogenetically and males of this species are not known. Artificial parthenogenesis: ·          In normal conditions some eggs do not develop unless they are fertilized. ·          In such conditions, when ripe egg is induced artificially the development start

Introduction to Cell Biology -          Cell was discovered by Robert hook -          He has observed compartment like structure in section of cork -          Cell Theory:  All organisms are made up of cells. This theory was proposed by Scheilden & Schwan -           Modified version o f Cell theory: All the organisms are made up of cell & cell products. -          Types o f Cells:  There are two types of cells viz. 1.      Prokaryotic cell 2.      Eukaryotic cell 1.      Characters of Prokaryotic Cell:                                i.             The cells in which nuclear membrane and cell organelles are absent are called as prokaryotic cell.                              ii.             The region in prokaryotic cell where DNA is present is called as nucleoid region/nuclear region .                           iii.             DNA is in the form of circular DNA.                           iv.             Different enzymes required for cellul
