Q34 / 180 · NEET 2019 (Odisha) · Botany

Select the correct sequence of events

  • Correct answer
    A
    Gametogenesis $\rightarrow$ Gamete transfer $\rightarrow$ Syngamy $\rightarrow$ Zygote $\rightarrow$ Cell division (Cleavage) $\rightarrow$ Cell differentiation $\rightarrow$ Organogenesis
  • B
    Gametogenesis $\rightarrow$ Gamete transfer $\rightarrow$ Syngamy $\rightarrow$ Zygote $\rightarrow$ Cell divison (Cleavage) $\rightarrow$ Organogenesis $\rightarrow$ Cell differentiation
  • C
    Gametogenesis $\rightarrow$ Syngamy $\rightarrow$ Gamete transfer $\rightarrow$ Zygote $\rightarrow$ Cell division (Cleavage) $\rightarrow$ Cell differentiation $\rightarrow$ Organogenesis
  • D
    Gametogenesis $\rightarrow$ Gamete transfer $\rightarrow$ Syngamy $\rightarrow$ Zygote $\rightarrow$ Cell differentiation $\rightarrow$ Cell division (Cleavage) $\rightarrow$ Organogenesis

Solution

The correct sequence of events are Gametogenesis (i.e. production of gametes) $\rightarrow$ Gamete transfer (i.e. movement of gamete at the site of fertilisation) $\rightarrow$ Syngamy (i.e. the fusion of gametes) $\rightarrow$ Zygote (i.e. a eukaryotic cell formed by fertilisation of gametes) $\rightarrow$ Cell division (cleavage) $\rightarrow$ Cell differentiation (i.e the process where a cell changes from one cell type to another) $\rightarrow$ Organogenesis (i.e. the process of formation of three germ layers).

Hence, the correct answer is option: 'A'.
