Question

Which group is incorrectly paired with its description?
a. diatoms—important producers in aquatic communities
b. red algae—eukaryotes that acquired plastids by secondary endosymbiosis
c. apicomplexans—unicellular parasites with intricate life cycles
d. diplomonads—unicellular eukaryotes with modified mitochondria

Accepted Answer

Hello everyone. And in today's video we're going to be taking a look at this problem stating all of the following are correctly paired with the description except so we need to identify the exceptions or question. We need to identify which group of organisms is incorrectly paired with the description. So this taxonomic question really requires a lot of memorization. So let's look over the description of of each organism so that we can compare it to their description in the answer choices. Starting with diatoms. Yeah the diatoms in the answer choices are a major producer in the aquatic system and this is actually a true statement. There are type of plankton that is able to photosynthesize. So there are a major producer of oxygen to take C. 02. And they transformed they produce oxygen through photosynthesis. And so we're going to cancel this out as a correct statement. Moving on, we have UPI complexion and this is stated to be a malaria parasite which is actually two as well. It's an animal parasite that is able to transmit malaria. So we're going to also cancel out as being a correct statement. Moving on. Finally we have diplo monets and these are prosthetic flagellating, uni cellular. These uni cellular organisms are able to have what we call a mythos um which is a modified mitochondria which is only present in certain very specific uni cellular organisms. So this is also a true statement. All living us with real foggy as their only possible answer choice reading over the statement we have the you carry. It's very curious that acquire plastic by secondary and the symbiosis. Most of these statement or most of these definition is actually correct, except by the time secondary they actually acquire their classmates, they acquire the chloroplasts via primary and the symbiosis. So this is the only part of the question that is incorrect or the only part of the statement that is incorrect. And so this is actually our correct answer choice. It is the exception to our question. So thank you very much for sticking around until the end of this video, and I really hope it helped you.
