Rapid plant movement facts for kids
Plants can move, and some of their movements are incredibly fast! We call this rapid plant movement. These quick actions usually happen in less than a second. It's like a blink of an eye! Plants use these fast moves for different reasons, such as catching food or spreading their seeds.

How Plants Move Fast
Many plants move very slowly. You might not even notice them growing or turning towards the sun. These slow movements are called tropisms. But some plants have special ways to move super quickly. They can snap shut, explode, or even launch things!
Super-Fast Plant Examples
Some plants are famous for their amazing speed. Let's look at a few examples.
The Speedy Venus Flytrap
The Venus flytrap is a well-known example of a fast-moving plant. It has special leaves that look like a trap. When an insect touches tiny hairs inside the trap, it snaps shut in about 100 milliseconds. That's faster than you can blink! This helps the plant catch its insect meal.
Other Carnivorous Plants
Some other carnivorous plants also move quickly to catch food. For example, bladderworts live in water. They have tiny traps that suck in small water creatures in a flash.
The Exploding Dogwood Bunchberry
The Dogwood Bunchberry (Cornus canadensis) has a flower that opens and fires its pollen in less than half a millisecond. That's incredibly fast! It helps the plant spread its pollen quickly.
The Record-Breaking White Mulberry
The White Mulberry tree (Morus alba) holds the record for the fastest plant movement. Its leaves are used to feed silkworms. But it's also amazing because of how fast it releases its pollen. The pollen is launched at more than half the speed of sound! The plant's stamens (the parts that hold pollen) act like tiny catapults. They release stored energy in just 25 microseconds. This is one of the fastest movements ever seen in nature!
The Touch-Me-Not Plant
The Impatiens plant is often called "touch-me-not". This name comes from its seed capsules. When these capsules are ripe, they "explode" if you touch them. They shoot seeds several meters away! This is a clever way for the plant to spread its seeds far and wide.
The Shy Mimosa Pudica
A plant that moves a bit slower, but still very noticeably, is Mimosa pudica. When you touch its leaves, or even if it gets dark, its small leaflets fold inward. They close up in a graceful sequence. It's like the plant is shy or going to sleep.
Studying Plant Movements
Long ago, a famous scientist named Charles Darwin was very interested in how plants move. In 1880, he published a book called The Power of Movement in Plants. It was his last big work before he passed away. He studied many different ways plants move, both fast and slow.
