Accepted Answer

Welcome back everyone here's our next problem. It says identify the features shared by gymnast firms and angiosperms. Well to start with when we think of gymnast sperms and angiosperms. Something that immediately comes to mind. At least for me when I think of those two things are that those are the seed bearing plants. So seeds are kind of things we can recall from our content video that should come to mind immediately with those two groups. So as I'm looking through my answer choices I'm going to look for the ones that include seeds. So I see the only choice C. And Choice D. Includes seeds. Now I do want to be careful and look at my other choices because it doesn't say identify all the shared features. It just says features shared. So I might get tripped up if one of our answers that includes seeds has something that they don't share. So just briefly glance over A. And B. Before eliminating them we see Choice B says the presence of vascular tissues and Dominic Spotify dominant sport of fighting generation only. So that only is our key. That that will not be our correct answer because it uh it does, seeds are common to them both. So that would make choice be incorrect. Choice A. Says absence of vascular tissues. Um Both gymnast firms and angiosperms are vascular plants so that automatically is incorrect. So Choice A. Is not our answer. So let's look through our choice C. And D. And see which one is correct again. Both have seeds which are common to both. Um Choice C. And D. Both say presence of vascular tissues. And as we discussed gymnast sperms angiosperms. The seed bearing plants are both vascular plants. They have that xylem and flow um So that doesn't distinguish between them. The next phrase is dominant sport prophetic generation. And as we recall, plants have the alternation of generations and the dominant generation would mean that one of those generations, whether multicellular hap Lloyd or multicellular deployed is the more prominent and long live stage. So the spore, if I tick generation is the multicellular deployed form and in those seed bearing plants that is the dominant generation that arose later in evolution. The more primitive plants like the mosses have a dominant prophetic generation. But later in evolution there arose all the plants that have a dominant sporadic generation. So we see that's in both C. And D. Common to both. We see the only difference here is that Choice D. Includes flowers while the angiosperms are flowering plants. But gymnast sperms though they are seed bearing do not have flowers. So flowers is not a common feature of both. And therefore Choice D. Is not correct. So identify the features shared by jim no sperms and angiosperms that would b. Choice C. Presence of vascular tissues dominant specific generation and seeds. See you in the next video
