reproduction and development

• Reproduction

  biological process by which offspring are produced from their parents

  involve the use of sex cells and the fusion of male and female gametes to form a zygote
• Asexual reproduction

  does not involve gametes, instead parts of mature organism may develop to new individuals. offspring is genetically identical to parent

  separation of the body into two new bodies. common in single-celled organisms such as bacteria
• Budding

  a new organism develops from as an outgrowth from the parent body known as bud. once grown, the new organism detaches from the parent body.
• fragmentation or regeneration

  the parent body will break into several pieces where each piece grows into a new individual
• vegetative propagation

  a plant part such as stems, leaves, roots or turions are used to reproduce new plant.
• natural vegetative propagation

  without human interference

  
  

  artificial vegetative propagation

  with the need of human interference
