Cell life questions and analogies
1.) Cells are complex and incredible structures that through series of reactions can create cellular energy, reproduce genetic material and eliminate waste products. Eukaryotic cells are more complex than prokaryotic cells and it is believed that they evolved from prokaryotes. What are 3 major characteristics that distinguish eukaryotes from prokaryotes? Choose 2 pieces of evidence (that we learned about in class) and explain how they support the theory that eukaryotes evolved from prokaryotes.
Eukaryotes and Prokaryotes differ in many ways, although, there are three major differences. One of these differences is that Prokaryotes do not contain a nucleus; Eukaryotes contain a nucleus. The second major differences is that Prokaryotic cells are much smaller than Eukaryotic cells. This is probably the most obvious difference. Eukaryotic cells are much larger and contain things that look like smaller cells inside of them. (Mitochondria and little chloroplast, which are necessary for survival in Eukaryotic cells.) The third major difference is that Prokaryotes have no organelles; Eukaryotes have organelles and are divided into many different functional components. Even though these cells have clear differences, scientist believe that Eukaryotes evolved from Prokaryotes. How??? Evidence 1: Every cell is closed by a membrane that regulates passing materials between a cell and its surroundings. Evidence 2: All cells use DNA to code genetic information. These two pieces of evidence lead to our answer.. Going back to Eukaryotic cells being much larger and looking like it has smaller cells inside of them..,. Both the Mitochondria and chloroplast look like they could have been their own independent cells at one point and each carry their own DNA and cell like membrane (which relates to our evidence). The theory is that these organelles in the Eukaryotic cell were once free living prokaryotes that moved into or evolved into a much larger cell. ( Symbiotic
