• Sperms


  are Produced by the testes. The sperms are very small in size with a head, a middle piece and a tail
• Eggs (ova)


  are produced by the ovaries
• Fertilization 


  The semen contains millions of sperms. A single sperm fuses with the ova during fertilization
• Internal Fertilization 


  The fertilization that takes place inside the body of the female
• Oviparity


  The Fertilized eggs are laid outside, where they receive nourishment from the yolk
• Ovoviviparity 


  The Fertilized eggs are retained in the female's body where they receive nourishment from the yolk. The eggs are laid right before they hatched
• Viviparity


  The offspring are born directly instead of hatching from the eggs
• External Fertilization 


  The Fertilization that takes place outside the female
• Embreyo Development 


  The Zygote divides repeatedly to form a ball of cells
• Asexual reproduction 


  It is the process in which a new individual is formed by the involvement of a single parent without the involvement of gamete formation
• Binary Fission 


  It is seen in amoeba and euglena. The parent cell undergoes mitosis and increases in size
• Budding 


  In this, The Offspring grows out of the body of the parent. It remains attached to the parent until it matures
• Fragmentation 


  In some organisms like Planarians, When the body of an organism breaks into several pieces esch piece grows into an individual offspring
• Parthenogenesis 


  This is form of asexual reproduction where the egg develops without fertilization
