Binary Fission• Bacteria begins to grow until it

has doubled in size

• Replicates DNA

• Divides to make 2 daughter cells

• No exchange of genetic material = asexual reproduction

Conjugation• Protein bridge forms

between bacteria cells

• Genetic material passed between bacteria

• Genetic exchange = sexual reproduction

• Increases genetic diversity

Spore Formation

• Formed when living conditions become unfavourable

• Enclose DNA and cytoplasm in endospore

• Able to stay dormant until conditions improve

• Technically not reproduction, be a method to prolong life
