When you hear the words “botany” and “plant science,” they might sound like the same thing. After all, their names are often used interchangeably, and they both study plants. But, when it comes to their goals, focus, and what kind of roles are in the field, the two areas of science are different.
This guide will walk you through those differences, whether you’re curious about the science behind your garden, thinking about a future career, or just want to understand how scientists study plants.
What Is Botany?
Just like plant science, botany is the scientific study of plant life, like how plants grow, how they’re structured, and how they interact with the environment and other plants. Because there’s no way we can identify every kind of plant in just a few years, botany also looks for and classifies new plants. At the Missouri Botanical Garden, there’s 200 new plant species discovered each year, and that’s just 10% of the worldwide discoveries.
But there’s more to botany than scientific discoveries. It also focuses on:
- Plant biology
- Structure
- Ecology
- Taxonomy
We can use plants to improve medicine, clothing, and other products we use everyday. Botany helps us appreciate, understand, discover, and protect the natural, and useful, greenery of our world.
The field of botany typically has roles like researcher, conservationist, and educator.
What Is Plant Science?
Plant science is a modern science that builds on the tradition of botany. It encompasses all things plants, especially plants used in agriculture. This is important for growing populations all around the world, who need more and more food and sustainable ways to grow it. Plant science incorporates technology to help plants endure droughts, resist pests, and survive climate change.
Because plant science is not as concerned with discovering new kinds of plants, it’s a much broader and more comprehensive field that focuses on:
- Agriculture
- Sustainability
- Crop genetics
- Biotechnology
- Weed control
- Fertilization
- And more
Plant science solves big problems, like food insecurity, with big solutions, like sustainable agriculture and plant breeding. Because it largely affects our food, it has a direct impact on our everyday lives, and the lives of future generations.
This area of science usually has workers like environmental scientists, soil scientists, and agronomists.
Side by Side
When you’re looking at the big picture, it can be hard to see where botany and plant science differ. So here’s a helpful comparison chart:
| | Botany | Plant Science |
| Goal | Identify and understand plants for their own sake | Apply plant knowledge to solve real problems |
| Focus | Plant biology, structure, ecology, taxonomy | Agriculture, sustainability, genetics, biotechnology |
| Typical Roles | Researcher, conservationist, educator | Environmental scientist, soil scientist, agronomist |
Why They Both Matter
Both botany and plant science are essential to understanding, using, and conserving plants for our benefit. Botany takes the first steps toward understanding plants, such as identifying, naming, and breaking down their biology. Plant science then applies this knowledge to agriculture and sustainability. Plant science can’t exist without the foundation of botany, and botany can’t help communities and industries without the application of plant science.
The difference between botany and plant science doesn’t look all that big from far away, but when you look at the little details, like their goals, focus, and the typical roles you can find in the fields, it becomes a lot clearer.
