In this abbreviated diagram, identify the four major plant groups and the key terrestrial adaptation associated with each of the three major branch points.

Question

Diagram showing four major plant groups and their adaptations from ancestral green algae.

Accepted Answer

Hey everyone. Let's take a look at this question together, arrange the following plant groups in chronological order, starting with those that first appeared on the land and progressing towards those that have most recently evolved. Let's take a look at the plant groups that were given and try and figure out which ones came before the others. So we we know that angiosperms are those flowering plants which we see today. So flowering plants. And we also know that they are the ones with those enclosed seeds that are found in fruits. So enclosed seeds. And then we know that bryan fights are actually the first vascular land plants. So they are first vascular land plants, meaning that they're very early on in the plant group evolution. And then seedless vascular plants we know are those seedless vascular plants and then also the gym no sperms are the vascular plants as well. But these are the ones with naked seats. So their vascular plants with naked seeds which differs from the angiosperms because we know that the angiosperms are the ones with those enclosed seeds. And so looking at how we have this written out, we can see that we know that the bro fights have to be first because they were the first vascular land plants. So we have to start with two. And then after that comes the seedless vascular plants. And so since we have two and three first we can immediately cross off answer choices C. And D. Since we're looking for two and three and our answer choices. And so looking at the next ones, we know that jim knows sperms came before angiosperms because they have those naked seeds instead of those enclosed seeds. And so that would make it 234 and then one which makes answer choice A the only correct answer based on the chronological order of the evolution of these plant groups. Because we started off with Bruno fights and then evolved through seedless vascular plants into gymnast sperms. And then most recently we have our our angiosperms. So answer choice is a correct answer. Hope you found this video to be helpful. Thank you and goodbye.
