Detailed explanation-1: -A scientist observes a new organism through a microscope. Which of the following observations tells her that the organism is eukaryotic? The organism has a membrane bound nucleus.
Detailed explanation-2: -which of the following observations tells the biologist that the organism is eukaryotic? It has membrane-bound organelles. Mitochondria and chloroplasts are structures found in the eukaryotic cells.
Detailed explanation-3: -You will know the cell you are looking at under the microscope is a eukaryote if you see a nucleus. This is the main distinguishing feature of eukaryotes and prokaryotes.
Detailed explanation-4: -Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell’s DNA is housed and the process of interpreting it begins.
