Introduction to Reproduction and Lifespan
  • Each and every organism can live only for a certain period of time. 
  • The period from birth to the natural death of an organism represents its life span.
  • Whatever be the life span, death of every individual organism is a certainty, i.e., no individual is immortal, except single-celled organisms. 
  • The life spans of organisms are not necessarily correlated with their sizes; the size of crows and parrots are not very different yet their life spans show a wide difference.
  • Similarly, a mango tree has a much shorter life span as compared to a peepal tree. 
  • The life cycle of an organism usually includes four stages:
    • Juvenility
    • Maturity
    • Ageing
    • Death 
  • Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. 
  • The offspring grow, mature and in turn produce new offspring.
  • Thus, there is a cycle of birth, growth and death. 
  • Reproduction enables the continuity of the species, generation after generation.
