Under adverse environmental conditions, Amoeba propagates via ________?
Show answer Hide answer
Answer: C. Encystment
Explanation
Amoebas undergo encystment, forming a protective wall around themselves to survive harsh environmental conditions. During unfavorable conditions like drying or food shortages, the cell rounds up and secretes a tough cyst wall. Metabolic activity drops significantly until favorable conditions return and the amoeba excysts. Protists are single-celled eukaryotic microorganisms that inhabit various aquatic and soil environments. Survival mechanisms in microbiology often involve dormant resting stages resistant to environmental stress. Cellular biology studies encystment to understand how microscopic organisms endure extreme stress.
Pathogenic amoebas use encystment as a strategy to survive transmission between different human hosts. Environmental monitoring tracks cyst forms in water treatment facilities to ensure public health safety. Understanding encystment helps researchers develop methods to disinfect contaminated water supplies effectively. Binary fission is standard asexual reproduction where a cell divides into two during normal conditions. Conjugation is a sexual exchange of genetic material rather than a stress survival dormancy mechanism. Endomixis is an internal nuclear reorganization process found in certain ciliates rather than amoebas.
