Document Summary

Live in habitats that are too cold, hot, salty, acidic and alkaline for eukaryotes to survive. Microbiota- the community of microorganisms that live in and on our bodies. Prokaryotes help carry out functions that are beneficial to humans and eukaryotes. 16. 2 external features contribute to the success of prokaryotes. Gram-negative: (pink) more complex and more likely to cause disease. Capsule: sticky layer of polysaccharides or protein. Enables prokaryotes to stick to their substrate or to other individuals in a colony. Flagella: enable them to move in response to chemical or physical signals in. Fimbriae: enables them to stick to surface and latch onto host cells environment. 16. 3 populations of prokaryotes can adapt rapidly to changes in the environment. Endospores: specialized cells that can survive extreme heat or cold. When endospore receives environmental cues that condition has improved, it absorbs water and grows. Chemotrophs : harness the energy stored in chemicals. Heterotrophs: carbon from organic compounds present in other organisms.
