Where is this question from??

My first guess would have been a) as well because blue-green algae = just another name for cyanobacteria but I guess I can see the reasoning behind the other choices. They're plant-like because they photosynthesize, protist-like because they can be unicellular...however, IMO if the answer really is d) this is either a horribly tricky-on-purpose question or kind of sloppily written (especially because protists and plants are in an entirely separate domain), lol. Just because they resemble a plant or a protist in one way or another doesn't mean they should be classified as that...😕

Well, that's just my $0.02.

Is this question from Kaplan? If so, another reason not to take their dumb class. The answer is A. There is no reasoning behind it being a plant - they are unicellular and prokaryotic. Plants are eukaryoktes and multicellular. Now, if they mentioned fungi, then it could be posibbly right, as they function as part of lichens and also as part of mycorrhize-fooshizee.

I concur with txlonghorn. He is correct about blue green algae.

on my real dat exam i had a question VERY similar to this except the answer choices were a lot tricker and there was no "all of the above" choice. it totally mind-****ed me, i was like ****! learn about this topic carefully.


like you prob already know, the bio section has about 10 questions that are random as hell and are like what the ****... this was one of them

correct me if im wrong, but arent some seaweed plants basically huge complexly organized colonies of protists???? thats how it can be classified as a plant.

This question asks about blue green algae, which are prokaryotes. So, no, they are not considered protist. I hate the people that make these questions.

 

[cm8a12321]

Blue-green algae, like txlonghorn wrote, is a "cyanobacteria". It is a photosynthetic prokaryote that is believed to give chloroplasts to a eukaryotic plant (protosymbiontic theory).

If you want, just think of this as the ancestor to the eukaryotic plant.

Cma812321,

What is considered the main evidence for the endosymbiotic theory?

lol I meant the endosymbiotic theory.

Sorry guys I posted trick BIO question. On destroyer and all other materials said it is classified as Monera, but I found this statement from one source.

Blue green algae can be classified in 3 different groups depending upon the taxxonomy used. They can be called Monerans because they lack a nuclear membrane and have a single naked chromosome, or they can be placed in the protista kingdom because they posses intermediate and hard to place traits. FInally they can be grouped with the plants because of their ability to photosynthesis.

So I guess, if we have an option for all of the above, we should choose it.

 

[txlonghorn]

I still wouldn't. Ap bio states that while they were once classified as algae, they are now classiied as monerans.
