The Future of Botany
S1 E15 - 12m 21s
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.

Can Planting Trees Fix Climate Change? (Plants & Biomes)
S1 E14 - 12m 24s
Whether in a desert, the savanna, or a tropical rainforest, plants have an important role in the ecological processes of Earth’s biomes. In this episode of Crash Course Botany, we’ll explore these different living locales, the effects of climate change on them, and how our photosynthetic friends make the world go ‘round.
-
How We All Get Our Energy (Plants & Ecosystems)
S1 E13 - 12m 53s
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
S1 E12 - 13m 15s
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
S1 E11 - 13m 46s
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 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?
S1 E10 - 13m 25s
All of the different plants on Earth—from mango trees to marigolds—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 how a botanist and mathematician named Gregor Mendel laid the groundwork for modern genetics.
-
Why Do Flowers Exist? (Gymnosperms & Angiosperms)
S1 E9 - 14m 4s
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)
S1 E8 - 13m 27s
Forget your favorite flowers, because we’re talking all about the mean green sporing machines. In this episode of Crash Course Botany, we 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?
S1 E7 - 13m 22s
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?
S1 E6 - 14m 44s
“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
S1 E5 - 12m 59s
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?
S1 E4 - 12m 43s
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.
