Rafflesia Arnoldii – Largest flower is parasite

Rafflesia Arnoldii – Rafflesia arnoldii, is the largest individual flower on Earth. It doesn’t have its own stems, leaves or roots. Parasites on vines of the Cissus genus, related to the vine. Deriving water and nutrients from the hosts. Rafflesia grows in a thicket of tropical jungles in Borneo and Sumatra.
It reaches a weight of 11 kg and a diameter of one meter. It consists of five fleshy, red, white speckled petals. Inside, it finds a few liters of nectar, and spike-like creations with an unknown function.
Rafflesia emit a specific, bad smell to rotten meat. In this way it attracts pollinating beetles and flies. That’s why the people of Indonesia call it a corpse flower. It blooms for 5-7 days, every few years. However, if pollinated, it produces round fruit. Containing thousands of tiny seeds.

Algae Chlamydomonas – Different colors of snow

Algae Chlamydomonas – Freshly fallen snow seems pure white, although the snowflakes are transparent. This is because they reflect white sunlight evenly. We found 100 species of plants that live in the snow, coloring it in green, brown, purple and even blood-red. The last color is represented by monocellular algae from the Chlamydomonas species living in the colonies behind the Arctic Circle. Because they absorb more solar heat than the surroundings, so the snow around them melts, and the algae sink into the pits that cover the ice layer from above. In such micro – greenhouses a constant temperature of around 0 ° C prevails.

Red, blue, white light tests – Surprising results

Red, blue, white light tests – In 2011. A team of British scientists led by Beau Lotta conducted an extensive experiment within eight weeks. 150 people have been exposed to light red, blue and white. Each light conducive to test for one minute. The researchers then asked respondents how much time has passed them by. The results were surprising – in light blue it seemed that time is running out quickly, and in the red – that clearly passes slowly. Specifically, an average of 11 s. According to B. Lotta red color allows us to fully understand the environment.

White whales – Result from albinism or leucism

White whales – White effect may result from albinism or leucism (disorder where the eyes remain normal color, whereas albinism are pink or pale blue, due to the show-through blood vessels in the iris without dye). Such coloration found so far in 20 species of cetaceans. The real Albinism confirmed in only a few (humpback whales, sperm whales, orcas and bottlenose dolphins). For example, of approx. 80 thousand. humpback whales living in the world are known only two completely white individuals.

Turquoise water color – Floating particles of limestone

Turquoise water color – For a beautiful bluish-colored waters Faaker See in Carinthia respond floating in the water, microscopic particles of limestone. Brings them power water stream flowing downhill mountain Mittagskogel in Karavanke (mountains on the border between Slovenia and Austria).

Although the water may seem clear, in fact, it is blue. You can not see it in a glass, but when we are dealing with a greater amount of it, eg. In a mountain lake, no longer so. Visible light, white, consists of all the colors of the rainbow, which behave differently in water. Water absorbs most of the waves the red end of the visible spectrum, blue light hand – far less, giving the blue color of the water. Well it shows where we are bottom of the highly reflective, eg. At a tropical beach with white sand.

Suspended particles of rock the size measured in microns, like those in Faaker See and other lakes renowned for its turquoise water, for example. Lake Louise in Canada, at least absorb green light. As a result, green and blue taken together give a water color of turquoise.
