How fast can a sandbox tree explode?
The sandbox tree, native to tropical America, has exploding capsules that can launch seeds up to 100 meters (330 feet) away with speeds of up to 70 meters per second (160 mph)! People have been injured by the force of those seeds, and the sound of the explosion can be heard echoing through the forest.
What fruit explodes?
Some types of exploding fruits, such as the squirting cucumber, utilize built-up water pressure to expel the seeds, while others, such as certain violets, employ the tension from the drying fruits to fling their offspring away.
What are some examples of dandelion fruit?
For example, each tiny dandelion fruit has a feathery “pappus” to help it catch a breeze (or a dreamer’s wish). Maple “whirlybirds” are winged fruits called samaras that spin their way to a new location. Some seeds, like those of the jacaranda, are “flutterers” and have papery edges to help them disperse.
Why do plants eat fruit?
As evidenced by the plethora of tasty fruits in existence, many plants rely on being eaten as a means to move their seeds about. For some, the strategy is simply to get an animal to eat the fruit and drop the seed directly (or for it to pass through a digestive tract unscathed). But certain other seeds actually require digestion in order to sprout. The hard seeds of blackberries, for example, must be abraded in a bird’s gizzard in order to break dormancy. Stomach acids and digestive enzymes wear down the hard seed coats in cherries and serve to make the seeds more permeable to water. And, of course, being deposited in a steamy pile of fertilizer never hurt a seed’s odds of a good start!
Why do mistletoes have sticky seeds?
Many mistletoes have explosive fruits with sticky seeds to (hopefully) propel their parasitic offspring high into neighboring trees.
Do squirrels eat acorns?
Some plants have coevolved with animals in such a way that their seeds are collected and helpfully buried in a clever symbiosis. Squirrels famously misplace their buried caches of acorns, which then have an excellent chance of germinating.
An Introduction To The Botany of Seeds
S eeds provide the vital genetic link and dispersal agent between successive generations of plants. Angiosperm seeds are produced and packaged in botanical structures called fruits which develop from the "female" pistils of flowers. Immature seeds (called ovules) each contain a minute, single-celled egg enclosed within a 7-celled embryo sac.
1. Gliders
The remarkable winged seed of the tropical Asian climbing gourd Alsomitra macrocarpa. The entire seed has a wingspan of 5 inches (13 cm) and is capable of gliding through the air of the rain forest in wide circles. This seed reportedly inspired the design of early aircraft and gliders.
2. Parachutes
An individual parachute of western salsify ( Tragopogon dubius) showing an umbrella-like, plumose crown of hairs (pappus) above a slender one-seeded fruit (called an achene). These fragile units can become airborne with the slightest gust of wind, and can literally sail across valleys and over mountain slopes.
3. Helicopters (Whirlybirds)
The South American tipu tree ( Tipuana tipu) has one of the most unusual legumes in the world. Unlike the fruits of most members of the legume family (Fabaceae), the 3rd largest plant family, the fruits of this tree have a distinctive wing that causes the legume to spin as it falls from the rain forest canopy.
5. Cottony Seeds & Fruits
Fuzzy brown cattail spikes ( Typha latifolia) contain dense masses of tiny seeds, each with a tuft of silky hairs. Each spike contains about a million seeds. They are shed by the millions in a cloud of white fluff.
6. Tumbleweed (Russian Thistle)
T he common tumbleweed or Russian thistle is a rounded, bushy annual introduced into the western United States from the plains of southeastern Russia and western Siberia in the late 1800s. The name "thistle" comes from the stiff, sharp-pointed, awl-shaped leaves.
7. Miscellaneous
Squirrel-Tail Grass ( Elymus elymoides ), formerly named Sitanion hystrix is an attractive grass native to the mountains and plains of the western United States. Seed-bearing sections (spikelets) of the flower spike (containing one-seeded fruits called grains and very long awns) are carried short distances by the wind.
