Question
Fertilization occurs after gametogenesis and before embryogenesis.
- True
- False
Hint:
First the gametes are produced then they fuse and then the offspring development starts.
The correct answer is 'True'.
The statement is true.
Gametogenesis is the process of production of gametes from haploid progenitor cells. Two morphologically distinct types of gametes (male and female) are produced through different differentiation programs in some higher plants and animals.
Fertilization is a multi-step complex process that takes 24 hours to complete. A male sperm meets a female egg to form a fertilized egg. This is the beginning of pregnancy and leads to her 280-day journey for a woman.
Embryogenesis is the process of initiating and developing an embryo from either a fertilized egg (zygote embryogenesis) or a somatic cell (somatic embryogenesis). Embryonic development follows a highly organized sequence of cell division, expansion and differentiation.
