so plants are cool August you want to show this medicinal purposes number one is plant is animal is poisonous you would die the plant that killed Socrates and I know that because I do know a lot of cool plants but I also know how to group them into similar categories in my head now today I'm going to show you how to group most flowering plants into two different categories today we have a whole bunch of flowering plants that we're going to plant by flowering plants I'm talking about the angiosperms which are any plants with flowers and those are different from the gymnosperms like pine trees the mosses the ferns and all of the other primitive plants every one of these flowering plants we got can be divided into one of two categories either a monocot or a dicot So, plants are cool. August, you want to show them this? Medicinal purposes. Number one. This plant is edible. Is poisonous. You would die. The plant that killed Socrates. And I know that because I do know a lot of cool plants, but I also know how to group them into similar categories in my head. Now, today, I'm going to show you how to group most flowering plants into two different categories. Monocots and Dicots. Today, we have a whole bunch of flowering plants that we're going to plant. By flowering plants, I'm talking about the angiosperms, which are any plants with flowers. And those are different from the gymnosperms, like pine trees, the mosses, the ferns, and all of the other primitive Every one of these flowering plants we got can be divided into one of two categories, either a monocot or a dicot. So, here's the backstory. For flowering plants, biologist had finally divided them up into two groups, the monocots and dictos, the members of which tended to share similar features. Here 1, 2, 3, 4, 5, 6. Dicots have petals generally in multiples of four or five. 1, 2, 3, 4, 5. Monocots typically have parallel veins while dicots are net veined. Watch, watch. If you pull up a monocot, most of the time it'll have these fibrous spreading or they call them adventitious roots. While the tap root, that's classic dicot. Stems. Cut the stem of a monocot in cross-section and you'll see something like this, vascular bundles scattered all around. While in dicots, they're usually at the edge. Cotyledons, this refers to parts in the seed. Monocots, also known as monocotyledons, means one cotyledons in the seed. And dicots, like this bean, have two. Okay. There's about 250,000 species of flowering plants in the world. And with the five characters that I just showed you, about 75% of those have been classified as dicots and about 23% have been classified as monocots. What that means is there's about 2% that don't fit the classification so well. Recently, they've revised our understanding of flowering plants. We think the evolutionary tree looks a bit like this. You see, early on a few groups broke off. And then other small groups came off of that. In the end, the monocots were classified here, and the dicots are classified here. But other than the water lily relatives and the magnolia relatives, which contain most of that other 2% of flowering plants, the rest are still monocots and dicots. Okay. Now go out and see if you can identify those plants. If you like what we're doing, of course, we got more videos up here to watch and you can subscribe to our feed. you
