Initiation: The process begins when environmental conditions become unfavorable for growth, such as lack of nutrients, extreme temperatures, or desiccation.
Cellular Changes: The parent organism (often a fungus or bacteria) undergoes specific cellular changes, including the development of specialized structures for spore production.
Spore Development: Within the parent cell, spores are formed through processes like mitosis or meiosis. The cell’s nucleus may divide to create one or more nuclei for each spore.
Encapsulation: Each developing spore is encased in a protective outer layer, often made of tough materials like chitin or protein, to help withstand harsh conditions.
Maturation: The spores mature, gaining the ability to survive in dormant states until favorable conditions return.
Release: Once mature, the spores are released into the environment. This can occur through various methods, such as bursting from the parent cell or being carried by wind, water, or animals.
Germination: When conditions become favorable again, the spores can germinate, developing into new organisms and repeating the life cycle.
