Plants

• What are the two methods of cloning plants mentioned in the video?


  Cuttings and tissue culture
• What is the main advantage of cloning plants?


  The clone is genetically identical to the original plant
• How does asexual reproduction differ from sexual reproduction in plants?


  Asexual reproduction produces genetically identical organisms, while sexual reproduction produces genetically diverse offspring
• What is rooting powder used for in plant cloning?


  It encourages the plant to develop roots
• Why is taking cuttings a simple method for cloning plants?


  Because it involves removing a small piece of the plant and dipping it in rooting powder
• What is the limitation of taking cuttings when a large number of clones is needed?


  It is not efficient for producing hundreds of clones
• What is the process used to produce many clones from a single plant?

  Tissue culture
• What happens to the small pieces of plant in tissue culture?


  They are incubated with plant hormones to stimulate growth
• Why must the conditions for tissue culture be sterile?


  To prevent the introduction of microorganisms like bacteria or fungi
• How does tissue culture benefit commercial plant nurseries?


  It allows growers to produce thousands of genetically identical plants quickly and cheaply
• What is one reason gardeners prefer clones produced by tissue culture?


  They can be certain of the desired characteristics, such as flower color
• What is one application of tissue culture besides cloning common plants?


  It is used to preserve rare species of plants
• What are the characteristics of clones produced by asexual reproduction?


  • Genetically identical to the original plant
  • Same characteristics as the parent plant
  • Example: flower color is consistent
• What is the significance of using plant hormones in tissue culture?


  • Stimulates growth of plant cells
  • Encourages development into fully grown clones
  • Essential for successful cloning process
• What are the advantages of cloning plants through cuttings versus tissue culture?


  Advantages of cuttings:

  • Simple and quick for a few clones
  • Requires minimal equipment

  
  

  Advantages of tissue culture:

  • Produces hundreds of clones efficiently
  • Ensures genetic uniformity
