multiple choice question\nwhich of the following is the best definition of endosymbiotic bacteria?\no bacteria that metabolize the waste products of another organism (prokaryotic or eukaryotic)\no bacteria that live inside of multicellular organisms\no bacteria that live within other cells and perform specific functions for their host cells\no bacteria that form an association with a eukaryotic single - celled organism
Answer
Brief Explanations:
Endosymbiotic bacteria are those that live within other cells and have a symbiotic relationship where they perform specific functions beneficial to the host cells. For example, mitochondria and chloroplasts are thought to have originated from endosymbiotic bacteria. The first option just describes bacteria using waste products, the second option is too general about bacteria in multicellular organisms, and the fourth option is too specific about association with only eukaryotic single - celled organisms.
Answer:
Bacteria that live within other cells and perform specific functions for their host cells
