Strange looking plants
|
view preview
The island of Socotra is one of the most isolated non-volcanic landforms in the world. Sitting 240 km east of the Horn of Africa and 380 km south of the Arabian Peninsula, its geographic isolation over millions of years has ensured that a third of its plant species are found nowhere else on Earth. Clockwise from the top are dragon blood trees, desert roses, and a native succulent, Dorstenia gigas. ...

House plants could one day power our computers
|
view preview
Researchers have discovered a novel method to harness photosynthesis to create electricity. By attaching nanotubes to plant cells, the researchers were able to direct the electrons that plants free during photosynthesis down a wire and generate electrical current – and it was twice as powerful as electricity gathered from solar cells.

This plant will solve all your termite problems
|
view preview
The pitcher plant, much like the Venus flytrap, is a carnivorous plant that survives by digesting insects. It's sweet nectar entices insects to feed off it, though this may come at a cost as they risk falling into a deadly pool of acid at the bottom of the pitcher plant's bucket-shaped leaf.

An amazing reaction happens when a plant gets hurt
|
view preview
The short clip above shows what happens to an injured plant when a nibbling insect attacks the leaves of a plant: the entire plant is alerted to begin anticipatory defense responses.Working in the model plant Arabidopsis, researchers recently showed that a systemic signal begins with the release of glutamate, which is perceived by glutamate receptor–like ion channels upon injury to a leaf. The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the phloem vasculature and through intercellular channels called plasmodesmata. This glutamate-based long-distance signaling is rapid; within minutes, an undamaged leaf can respond to the fate of a distant leaf. If plants react to injury more similarly to ...

The bleeding tooth fungus
|
view preview
The bleeding tooth fungus grows in Europe and North America. While young, the fungus looks like it is oozing blood. The red liquid is actually an anticoagulant. It lives on the roots of conifer trees and exchanges nutrients in a mutually beneficial relationship. And, if you're wondering, they are inedible.

World's largest seed
|
view preview
The coco-de-mer palm tree ( Lodoicea maldivica) is endemic to the Seychelles. Its seeds are the largest and heaviest of any plant in the world, and have been highly prized over the centuries, which has almost driven the palm tree to extinction.

Plants can be albino too!
|
view preview
This is an albino redwood tree, with white needles instead of green because it's unable to produce chlorophyll. In order to survive, albino redwoods must join their roots to those of a normal redwood to obtain nutrients. Found in Henry Cowell Redwoods State Park and Humboldt Redwoods State Park in the US, there are only around 20 known albino redwoods in the world, and their exact whereabouts have been kept secret as protection.

Seeds germinate after 2000 years
|
view preview
A Judean date palm plant was planted in 2005 using seeds that were hidden away for 2000 years. While other species of date palms thrive around the world, this particular species was thought to be extinct for 1800 years. Date palms are either male or female, and this one, nicknamed Methuselah, is a male, so it will not produce fruit. However, the plant is alive and well, and is the oldest known seed to successfully germinate.

Who knew chili peppers were good for you

Exposure to cold and eating chili peppers both appear to increase the activity of brown fat cells, which burn energy, rather than store it as typical "white" fat cells do, a study has found.

Proof that money does grow on trees
|
view preview
Well, okay GOLD. Apparently, gold grows on eucalyptus trees. Researchers discovered that the trees are acting as a hydraulic pump, extracting gold from the soil and moving it to their leaves and branches. The ‘nuggets’ are about one-fifth the diameter of human hair, but the leaves may be used in combination with other tools to develop better exploration techniques.

Pine cones the size of melons!

The Australian Bunya pine drops pine cones that are the size of melons. The cones are 20–35 cm in diameter, and are opened by large birds, such as cockatoos, or disintegrate when mature to release the large (3–4 cm) seeds or nuts.

Lithops are succulents that have evolved to avoid being eaten by animals by blending in with pebbles and stones. In botany, succulent plants, are plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. Succulent plants may store water in various structures, such as leaves and stems. ...

The world's tallest tree

Hyperion, ranked as the world's tallest known living tree, has not had its location revealed publicly for fear that human traffic would upset the ecosystem the tree inhabits. This fabulous tree is a coast redwood ( Sequoia sempervirens) found in Northern California that was measured at 115.61 m (379.3 ft).
