6.1.1 Sexual and Asexual Reproduction

• Why is increased genetic diversity a benefit of sexual reproduction?

  Adaptation to environment
• Asexual reproduction allows for rapid population growth and is energy-efficient.


  True
• Sexual reproduction involves the fusion of gametes to create genetic diversity
• What are the two types of gametes involved in fertilization in animals?

  Sperm and egg
• Asexual reproduction results in offspring that are genetically identical to the parent
• Asexual reproduction results in populations that are vulnerable to environmental changes due to a lack of genetic diversity.


  True
• Match the characteristic with the type of reproduction it applies to.

  Gametes ↔️ Fusion of two gametes

  Genetic Diversity ↔️ Unique genetic makeup

  Fertilization ↔️ Fertilization occurs between gametes

  Offspring ↔️ Clones of the parent
• Order the key processes in sexual reproduction.

  1️⃣ Fertilisation

  2️⃣ Gamete formation

  3️⃣ Mixing of genetic material
• What is the primary characteristic of sexual reproduction?

  Fusion of gametes
• Order the key processes in sexual reproduction.

  1️⃣ Fertilisation

  2️⃣ Gamete formation

  3️⃣ Mixing of genetic material
• Sexual reproduction leads to increased genetic diversity, which helps populations adapt to environmental changes.


  True
• Give an example of an organism that uses asexual reproduction through fragmentation.

  Planarians
• In sexual reproduction, offspring inherit a unique combination of genes from both parents
• Which type of asexual reproduction involves cell division into two identical cells?

  Binary fission
• Asexual reproduction results in offspring that are genetically identical to the parent
• Fertilisation in animals involves the fusion of sperm and egg.


  True
• Match the type of asexual reproduction with its description.

  Binary Fission ↔️ Cell divides into two identical cells

  Budding ↔️ New organism grows from an outgrowth

  Fragmentation ↔️ Organism breaks into fragments

  Parthenogenesis ↔️ Embryo develops from unfertilized egg
• Which type of asexual reproduction is used by bacteria and amoebas?

  Binary fission
• Which type of asexual reproduction involves the division of a cell into two identical cells?

  Binary fission
• What is the key disadvantage of asexual reproduction in terms of adaptability?

  No genetic diversity
• Asexual reproduction is more energy-efficient than sexual reproduction.


  True
• What type of cells are gametes?

  Haploid
• Increased genetic diversity in sexual reproduction helps populations adapt to environmental changes.

  True
• The fusion of two gametes is called fertilization
• Match the key process of sexual reproduction with its description:

  Fertilization ↔️ Fusion of gametes

  Gametes ↔️ Haploid cells

  Mixing of Genetic Material ↔️ Offspring inherit unique genes
• What is one benefit of sexual reproduction?

  Reduced genetic disorders
• Arrange the key processes of sexual reproduction in the correct order:

  1️⃣ Fertilization

  2️⃣ Gametes formation

  3️⃣ Mixing of Genetic Material
• What is one benefit of sexual reproduction?

  Adaptation to change
• Match the type of asexual reproduction with its description:

  Binary Fission ↔️ Cell divides into two

  Budding ↔️ New organism grows from outgrowth

  Fragmentation ↔️ Organism breaks into fragments
• What is one benefit of asexual reproduction?

  Rapid population growth
• Limited genetic diversity in asexual reproduction makes populations vulnerable to environmental changes.


  True
• Arrange the main types of asexual reproduction in alphabetical order:

  1️⃣ Binary Fission

  2️⃣ Budding

  3️⃣ Fragmentation

  4️⃣ Parthenogenesis
• Match the type of asexual reproduction with its description:

  Budding ↔️ A new organism grows from an outgrowth

  Fragmentation ↔️ The parent organism breaks into fragments

  Parthenogenesis ↔️ An unfertilized egg develops into a new individual

  Binary Fission ↔️ A single cell divides into two identical cells
• Increased genetic diversity in sexual reproduction allows populations to adapt to environmental changes
• Asexual reproduction allows organisms to reproduce quickly and efficiently, resulting in rapid population growth
• Increased genetic diversity in sexual reproduction helps populations adapt to environmental changes.

  True
• Asexual reproduction involves a single parent producing genetically identical offspring
• Match the type of asexual reproduction with its example:

  Binary Fission ↔️ Bacteria

  Budding ↔️ Yeast

  Fragmentation ↔️ Starfish

  Parthenogenesis ↔️ Reptiles
• Asexual reproduction is more energy-efficient because it does not require fertilization
• Match the process in sexual reproduction with its description:

  Fertilization ↔️ Fusion of sperm and egg

  Gametes ↔️ Haploid cells with half the genetic material

  Mixing of Genetic Material ↔️ Offspring inherit unique traits
