The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - Correct answer-true In your own multicellular body, cells with different functions have different DNA. - Correct answer-false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - Correct answer-true The paramec...

Cell theory idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells Endosymbiotic theory eukaryotes may have been a product of one cell engulfing another, one living within another, and evolving over time until the separate cells were no longer recognizable Evidence of endosymbiotic theory eukaryotes consumed prokaryotes (leading to mitochondria), or eukaryote consumed photosynthetic...
