There are so many different ways that plants spread their seeds. No one believes that any seed pod can explode with this violence, so we have begun to experiment. Maddie Moate explains seed dispersal, Cheetah vs Greyhound, a speed test in slow-motion, Broccoli sprouts growing in a jar, a time-lapse. It is an … _____ Curated, kid-friendly, independently-published. Since plants do not have muscles; rapid movements, like the exploding seed pods of popping cress, are rare in the plant kingdom. It was actually, M, one of the kids who built that amazing 2-story fort, who taught me what it was. A mathematical model explains the explosive dispersal of seeds from the popping cress. Explosive shatter of these seed pods is so fast that advanced high-speed cameras are needed to even see the explosion. Plants use many strategies to disperse their seeds, but among the most fascinating are exploding seed pods. These are all stuck in there with the seed and when you touch it that outside explodes in these coils, just explode and send the seeds flying these are seriously one of my favorite things. This study is an example of the potential of interdisciplinary research. Explode a balloon seed pod. According to Hay, their most exciting discovery was the evolutionary novelty of this hinged cell wall. Euphorbia is another plant whose seedpods crack open with a loud explosion. Watch a leaf “breathe” Plants use many strategies to disperse their seeds, but among the most fascinating are exploding seed pods. Spark questions. By shooting those black seeds out, Impatiens gets a higher chance of dispersing its offspring. The blue lines are computer simulations of the coiling seed pod at consecutive time points. The scientists built up a comprehensive picture of explosive seed dispersal by relating observations at the plant scale all the way down to the cellular and genetic scales, and systematically linking each scale. It's fascinating watching the tiny seeds sprout and grow into plants that then bloom with flowers before producing new seeds.… In both the toy and the seed pod, the cross-section first has to flatten before the tension is suddenly released by coiling. Hence, Impatiens has the common name, touch-me-not. Start conversations. The sandbox tree sends its seeds hurling nearly 150 feet, and the exploding seed pods create a loud noise comparable to a rifle discharge. As Moulton explains, “This wall is shaped like a hinge, which can open,” causing the fruit wall to flatten in cross-section and explosively coil. 3 1/2 oz dry, organic potting soil; 1 1/2 oz dry clay (we suggest powdered red pottery clay) Water; Scientists have built a mathematical model to explain the explosive dispersal of seeds from a … Inspire offline exploration.

After working out how the seed pods of popping cress exploded, the scientists realised that this mechanism had evolved via tweaking the shape of already-existing cellular components. After you learn about pollination, take the next step, and explore how plants disperse their seeds far and wide. So what puzzled the researchers was how popping cress pods exploded while green and hydrated, rather than brown and dry. Impatiens seed pods explode once touched. The pods of violets dry out, squeezing the seeds until they launch into the air, according to AbundantNature.com. Exploding seed pods. And it's free for everyone. Richard Bomphrey, of the Royal Veterinary College at the University of London, explains: “Because the seeds are so small, aerodynamic drag slows them down immediately.” To compensate, the seeds are accelerated away from the fruit and get up-to-speed extremely quickly. Anyway, that’s the sign that fall has arrived. Slow-Motion Explosion. Exploding Plant Pods! • Roll on the ground (families roll five times).
