Differentiate cellular and plasmodial slime molds. How does each survive adverse environmental conditions?

Question

Accepted Answer

Hello, everybody. Welcome back. The next problem says in spore forming bacteria, the formation of spores allows them to a rapidly reproduced b survive in their habitat. C resist adverse environmental conditions or d all of the above. So let's think about why bacteria forms spores. And that is when the environmental conditions are so harsh that it wouldn't otherwise be able to survive. They form these spores that are extremely thick walled and have very low activity. So minimal respiration, minimal metabolism that can just exist in these extremely harsh conditions. And so they can survive extreme heat, toxic chemicals, nutrient depletion in the state. So choice C is definitely a correct answer, but we do have that option of all of the above. So we need to like take a close look at our other choices to make sure we don't have more than one correct answer to say is rapidly reproduced. Well, this might hold us up for a second because we can recall that fungi have reproductive spores. But we're specifically asked about bacteria and bacteria. Those spores again are just for these very harsh conditions. They have this minimal meta metabolic activity and they don't reproduce. So for bacterial spores there they begin and end as just a single cell, the choice A is not correct, which also eliminates choice D all of the above. So we now know that C must be our answer and B must be incorrect. We'll just take a quick look at it to be thorough. B says survive in their habitat which might confuse us a little if we hadn't already eliminated it. Um But think about the fact that when this choice says survive in their habitat, they're talking about all conditions including normal conditions that have plenty of nutrients, moisture, good conditions for the bacteria to live. They don't need to be spores at that point. So the formation of spores, you wouldn't say allows them to survive under normal circumstances. So since they don't need to be in spore form to survive in normal circumstances, you wouldn't say that surviving in their habitat is what for this formation of spores allows them to do so. Once again, in spore forming bacteria, the formation of spores allows them to choice c resist adverse environmental conditions. See you in the next video.
