Crash Course: Botany
(2023)Streaming Episode Guide
Season 1
Over the course of 15 episodes, we’re going to learn about botany—the study of plants. Alexis Nikole Nelson will teach you about how plants evolved, how they function, and just how vital they are to human societies and all of life on Earth. This content is based on an introductory university-level curriculum. By the end of this course, you should be able to: *Describe the evolutionary history of plants *List and describe fundamental anatomical and morphological characteristics of plants *Understand what plant hormones are and how they work *Explain what roles plants play in ecosystems and why they are important *Understand how plant genes play an important role in the diversity of plants we see on Earth *Understand why plants are important, and how botanical knowledge can be useful in everyday lifeThe Future of Botany
Episode 15 - 9-07-2023
We’ve learned a lot about plants throughout this series, but there’s much more to discover. In this episode of Crash Course Botany, we’ll peek into the future of botany. We’ll consider current plant mysteries, bridges between Western science and traditional knowledge, and what it might take to garden on the moon.

How We ALL Get Our Energy (Plants & Ecosystems)
Episode 13 - 8-24-2023
From the driest deserts to the lushest forests, ecosystems are networks of life where organisms and the environment interact. In this episode of Crash Course Botany, we’ll explore how plants function as the foundations of these systems, without which no other life on Earth would be possible.

The Secret Social Lives of Plants (Population & Community Ecology)
Episode 12 - 8-17-2023
The social dynamics of plants are as complex as those at any high school. By studying how plants interact — one-on-one, as a population, and in their communities — ecologists can figure out how to conserve our photosynthetic friends. In this episode of Crash Course Botany, we’ll explore these complex relationships—and eavesdrop on all the hot plant gossip.

GMOs are Nothing New: Plant Breeding & Gene Editing
Episode 11 - 8-10-2023
Humans love to play with their food—in fact, we’ve been doing it for thousands of years. In this episode of Crash Course Botany, we'll explore how we’ve learned to manipulate plant genetics, from breeding tastier fruits and veggies to directly editing plant genes that help crops survive climate change. And if you’ve ever wondered what GMOs are or if they’re safe, we’ve got you covered.

What Do Pea Plants Have To Do With Your Eye Color? (Mendelian Genetics)
Episode 10 - 8-03-2023
All of the different plants on Earth have come about thanks to the simple rules of genetic inheritance, which determine how traits are passed on from one generation to the next. In this episode of Crash Course Botany, we’ll explore the remarkable story of Gregor Mendel, a botanist and mathematician who laid the groundwork for modern genetics with little more than some peas and a paintbrush.

Why Do Flowers Exist? (Gymnosperms & Angiosperms)
Episode 9 - 7-27-2023
You couldn’t go a day without interacting with gymnosperms and angiosperms, the two most prominent groups of plants on the planet. We rely on them for food, clothing, and shelter — but why are they so common? In this episode of Crash Course Botany, we’ll find out how their seeds and flowers propelled them to evolutionary success.

Why Don't These Plants Need Seeds? (Moss and Ferns)
Episode 8 - 7-20-2023
Forget your favorite flowers, because we’re talking all about the mean green sporing machines. In this episode of Crash Course Botany, we'll dive into the first few branches of plants’ phylogenetic tree—bryophytes and seedless vascular plants, like mosses and ferns. These plants are the unsung heroes of the botanical world, and we’re giving them their due.

How Do We Categorize Plants?
Episode 7 - 7-06-2023
Humans make stuff up—including the names and classifications of living things. But those categories are still useful. In this episode of Crash Course Botany, we’ll explore how taxonomy and systematics help us understand what plants are and where they come from. We’ll discuss the power of naming, and why even scientists don’t agree on what a species is.

How Did Plants Evolve?
Episode 6 - 6-29-2023
“You shouldn’t make decisions when you’re hungry.” Tell that to the cell that ate a bacterium 1.5 billion years ago and set in motion the evolution of all plants on Earth. In this episode of Crash Course Botany, we’ll explore how plants came to exist, the forces that drive plant evolution, and how we know what Earth’s prehistoric dystopia was like before plants came along.

Photosynthesis and Cellular Respiration
Episode 5 - 6-22-2023
Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of photosynthesis and cellular respiration work, why they’re so critical for all life on Earth, and how they’re helping us to forge a greener path to the future.

What Do These Creepy Plant Mouths Do? (Plant Tissues)
Episode 4 - 6-15-2023
Plants—they’re just like us! Well, not exactly, but they do have skin and hair like us…even if they also have creepy little alien mouths. In this episode of Crash Course Botany, we’re getting up close and personal with plants’ anatomy by diving right into plant tissue under a microscope. Let’s learn what plants are really made of.

Plant Cells & Hormones
Episode 3 - 6-01-2023
At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some wild features that set them apart from animal cells. In this episode of Crash Course Botany, we’ll ask: are plants more than the sum of their cells?
