Accepted Answer

Hi everyone. Here's our next question. The evolution of the pollen tube is parallel with the and choice is a success of seed plants on land. Be success of bryan fights on land, Sea suggestive algae on land or d success of all plants on land. Well, when we look at choice a seed plants and we're talking about the evolution of the pollen tube, A pollen tube delivers the male gametes or sperm to the female commit to fight. And this leads to um because allows double fertilization which leads to seed formation. So something specific to the seed bearing plants and what this pollen to provides is a safer and water independent means of sperm transport or sperm transfer, I should say. So we can see how the evolution of this pollen tube helped seed plants succeed on land because they didn't need water to deliver that sperm to the egg and to provide a safer way, allowing more reproductive success. So we can say that choice a success of seed plants on land is our correct answer. So let's just briefly touch on our other choices here choices be successive bryan fights on land. Well brian fights are things like mosses, liver work tog wert. Um But they need a wet transfer, which is why they grow in moist areas of sperm. So and they don't use a pollen tube. So they are not our correct answer choice. C says success of algae on land. They don't they do not use a pollen too and also need that water transfer of sperm. So no, that is not our answer about the evolution of the pollen tube and, finally, the success of all plants on land. Again, the evolution of pollen tube had to do with seed plants, So not choice D. Because specifically, it allowed the spread of seed plants on land. See you in the next video.
