NEET BIOLOGY

Detailed explanation-1: -David is observing a cell under a microscope. He observes a mitochondria. Which of the following is a conclusion he could draw? The cell is a prokaryotic cell.

Detailed explanation-2: -Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.

Detailed explanation-3: -In conclusion, prokaryotes and eukaryotes are both different and similar in many ways. The main thing to take away from this report is that prokaryotes are without a nucleus while eukaryotes have a nucleus. Also, prokaryotes maintain a single chromosome while eukaryotes have multiple chromosomes.

Detailed explanation-4: -Since the diameter of the mitochondrial tubules is generally close to the diffraction limit of light microcopy, it is often challenging, if not impossible, to visualize sub-mitochondrial structures or protein distributions using conventional light microscopy.

Detailed explanation-5: -Answer and Explanation: The main evidence that supports the notion that mitochondria proceeded plastid in the evolution of eukaryotic cells, is that mitochondria are present in all eukaryotic cells. Plastids, are only present in a few eukaryotic cells such as those a part of the plant kingdom.
