describes four features of bacteria that enable them to survive in a wide variety of habitats in life science grade 11
1) Small size: Bacteria are microscopic in size, which allows them to inhabit numerous environments, including soil, water, air, and the human body. Their small size enables them to withstand harsh conditions and easily access resources within their surroundings.
2) Rapid reproduction: Bacteria possess a high reproductive rate, allowing them to rapidly multiply and adapt to changing environmental conditions. Bacterial populations can double in number within a few hours, which enables them to compete with other organisms for limited resources.
3) Genetic diversity: Bacteria exhibit a high level of genetic diversity, which allows them to adapt to different environmental conditions. Their ability to exchange genetic material through horizontal gene transfer, such as through plasmids or conjugation, enables them to acquire new traits that aid in survival.
4) Dormancy and resistance mechanisms: Bacteria can enter a dormant state known as spore formation, which enables them to survive in harsh conditions, such as extreme temperatures or lack of nutrients. Additionally, bacteria possess various resistance mechanisms, including the ability to withstand high levels of radiation, toxins, or antibiotics, further enhancing their survival in different habitats.
