Sexual and Asexual Reproduction (SOME T)

• What are the two types of reproduction discussed in the video?

  • Sexual reproduction
  • Asexual reproduction
• How many pairs of chromosomes do human cells contain?

  23 pairs
• What is the process by which one cell is copied into two identical cells?

  Mitosis
• What are gametes in humans?

  Gametes in humans are sperm cells and egg cells.
• How many chromosomes do human gametes contain?

  23 single chromosomes
• What type of cell division produces gametes?

  • Meiosis
• How do the cells produced by meiosis differ from those produced by mitosis?

  Meiosis produces non-identical cells
• What is the process called when male and female gametes fuse?

  • Fertilization
• What is the result of the fusion of male and female gametes?

  Mixing of genetic information
• What is a key characteristic of offspring produced through sexual reproduction?

  • They show variation due to genetic mixing.
• How many parents are involved in asexual reproduction?

  One parent
• What are the offspring produced by asexual reproduction called?

  • Clones
• What type of cell division is involved in asexual reproduction?

  Mitosis
• How do offspring produced by asexual reproduction compare to their parent?

  • They are genetically identical.
• What are the two main types of reproduction discussed in the video?

  Sexual and asexual reproduction
• What are the advantages and disadvantages of sexual and asexual reproduction?

  Advantages of sexual reproduction:

  • Produces genetic variation
  • Increases survival chances in changing environments

  
  

  Disadvantages of sexual reproduction:

  • Requires two parents
  • Slower process

  
  

  Advantages of asexual reproduction:

  • Only one parent needed
  • More efficient in time and energy
  • Faster reproduction

  
  

  Disadvantages of asexual reproduction:

  • Offspring are genetically identical
  • Risk of all offspring dying if conditions become unfavorable
• How does sexual reproduction contribute to a species' survival advantage?

  It produces genetic variation that increases survival chances during environmental changes.
• What is the main advantage of asexual reproduction in favorable conditions?

  Asexual reproduction allows for rapid production of many genetically identical offspring.
• What is the risk associated with asexual reproduction?

  All offspring being genetically identical could lead to their collective demise if conditions become unfavorable.
• Which organism reproduces asexually in a human host and sexually in a mosquito vector?

  The malaria parasite reproduces asexually in humans and sexually in mosquitoes.
• How do many species of fungi reproduce?

  • Asexually by producing spores
  • Sexually to create variation in offspring
• How do strawberry plants reproduce asexually?

  Strawberry plants reproduce asexually by sending out runners that can develop into new genetically identical plants.
• What method do daffodils use for asexual reproduction?

  Daffodils reproduce asexually by bulb division, producing buds that form new genetically identical offspring.
