Class Round 2: Eudicots vs Magnoliids
Parsley, Sage, Rosemary and Thyme vs Bay Leaves and Black Pepper
Eudicots (“true dicots”): This is a ginormous class, containing almost all leafy trees, quite a lot of plants that humans get food from (including potatoes and all of the legumes), and the plants we get tea, coffee, and chocolate from. It also contains carnivorous plants, parasitic plants, and some very poisonous plants, as well as tobacco and cannabis.
Magnoliids: The third largest group of flowering plants, with over 10,000 species. Magnolias, tulip trees, bay laurels (as in crowned with laurels, as in the spaghetti sauce leaf), black pepper, cinnamon, nutmeg, avocados. Many species produce fragrant oils, including ylang ylang. MDMA (ecstacy) is derived from a chemical found in some Magnoliids trees.

Some representative examples of seeds from eudicots and monocots are shown in Figure 18.1. (...) Instead, the perisperm and storage cotyledons serve as the main sources of nutrients during germination (see Figure 18.1). (...) Specialized embryonic structures peculiar to the grass family include the following (see Figure 18.1):
The single cotyledon has been modified by evolution to form an absorptive organ, the scutellum, which forms the interface between the embryo and the starchy endosperm tissue.
The basal sheath of the scutellum has elongated to form a coleoptile that covers and protects the first leaves while buried beneath the soil.
The base of the hypocotyl has elongated to form a protective sheath around the radicle called the coleorhiza.
In some species, such as maize, the upper hypocotyl has been modified to form a mesocotyl. During seedling development, the growth of the mesocotyl helps raise the leaves to the soil surface, especially in the case of deeply planted seeds.

The ABC model accounts for many observations in two distantly related eudicot species (snapdragon and Arabidopsis), and provides a way of understanding how relatively few key regulators can combinatorially provide a complex outcome.

I wanted to make my own memory card so i scribbled a little skit leading up to the memory
And the card!

thinking about @plant-taxonomy-showdown's angiosperm cake poll and im contemplating how possible it is to bake a cake using ~~only~~ ingredients obtained from monocots (OR eudicots, but i've got that one figured out i think). i'm currently stumped by how you get air into that sucker without chemical leavening agents (aquafaba comes from eudicots so that's out).
so the solution would be like
bake something that's supposed to be dense, like ginger cake or banana bread. but the thought of making any of these without cinnamon is making me sad
stretch the definition of cake. maybe a pie is possible…?
reaaaaaaaaaaally stretch the definition of monocot-derived ingredient. like. what if i make ginger beer and use its CO2. that definitely can work (i've used cola as a leavening agent before). but then i'm relying on epidermally associated yeasts to make me the CO2, that feels like cheating.
but in theory, someone could run into a maize field at dusk, tie plastic bags around some (thousands) of plants, harvest the air before dawn, extract the CO2, pressurize it enough to blast it into water and then give me that carbonated water to use. does that count. plants make CO2 in the Kreb’s cycle so does it matter that the ginger beer's CO2 comes from a yeast digesting the ginger's glucose and not from the ginger burning its glucose how do you (imaginary arbiter of monocot cake law) know a yeast did it and not me breaking into a field at night with 10000 plastic bags i'm getting off track now.

Class Final Round!! Eudicots vs Monocots!
Grass (slang) vs Grass (literal)
Eudicots (“true dicots”): This is a ginormous class, containing almost all leafy trees, quite a lot of plants that humans get food from (including potatoes and all of the legumes), and the plants we get tea, coffee, and chocolate from. It also contains carnivorous plants, parasitic plants, and some very poisonous plants, as well as tobacco and cannabis.
Monocots: The second largest taxon in Magnoliophyta, with 70,000 species. Narrow leaves with parallel veins are a good sign you’re looking at a monocot, as are plants that grow from bulbs, like onions, garlic, and tulips. Do you need to touch grass? Monocot. Do you want to bake a cake? Wheat, sugar cane, and the orchids that produce vanilla extract are all monocots.

From this main root axis, lateral roots develop to form an extensively branched root system (Figure 5.8).
