Important points to remember about Reproduction in Organisms :

  1. Reproduction is defined as the process in which organism gives rise to young ones (offspring) similar to itself. 
  2. Reproduction is a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. . 
  3. When offspring is produced by a single parent with or without the involvement of gamete formation is called asexual reproduction.
  4. When two parents (opposite sex) participate in the reproductive process and also involve fusion of male and female gametes, it is called sexual reproduction.
  5. Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively simple organisations eg. Amoeba, Paramecium). 
  6. Organisms choose to reproduce asexually by different modes or ways like fragmentation, budding, binary fission, spore formation, Conidia formation, Gemmules formation.
  7. Vegetative Reproduction : Plants reproduce asexually through their vegetative parts. Hence, the new plants formed are genetically identical to their parents.
  8. Sequential events that occur in sexual reproduction are grouped into three distinct stages are 1. Pre-fertilization, 2. Fertilization and the 3. Post-fertilization.
  9. Syngamy (fertilisation) occurs between the male and female gametes. Syngamy may occur either externally, outside the body of organisms or internally, inside the body. Syngamy leads to formation of a specialised cell called zygote.
  10. The process of development of embryo from the zygote is called embryogenesis. In animals, the zygote starts developing soon after its formation. 
  11. Animals may be either oviparous or viviparous. Embryonal protection and care are better in viviparous organisms.
  12. In flowering plants, after fertilisation, ovary develops into fruit andovules mature into seeds. Inside the mature seed is the progenitor of the next generation, the embryo.
