The structure of pollen

Each pollen grain contain vegetative cells only one in the greater part flowering plant but several in other seed plants and a generative cell contain a tube nucleus that produces the pollen tube and a generative nucleus that divide to form the two sperm cells. The group of cells is surrounded by a cellulose cell wall and a thick, rough outer wall made of sporopollenin.

Pollen is created in the microsporangium contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants. Pollen grains come in a broad multiplicity of shapes, sizes, and surface markings characteristic of the species see photomicrograph at right. Most, but surely not all, are spherical, Pollen grains of pines, firs, and spruces are wing. The minimum pollen grain that of the Forget-me-not plant (Myosotis sp.), is approximately 6 µm (0.006 mm) in diameter.

Pollen grains may have furrows, the course of which classify the pollen as colpate or sulcate. The number of furrows or pores helps categorize the flowering plants, with eudicots having three colpi (tricolpate), and other groups having one sulcus.

Earth's atmosphere

Earth's atmosphere is a layer of gases surrounding the planet Earth and retain by the Earth's gravity. It contains roughly (by molar content/volume) 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide; trace amounts of other gases, and a changeable amount (average around 1%) of water vapor. This mixture of gases is usually known as air. The atmosphere protects life on Earth by captivating ultraviolet solar radiation and reducing temperature extremes between day and night.

There is no exact border between the atmosphere and outer space, it slowly becomes thinner and fades into liberty. Three quarters of the atmosphere's mass is within 11 km of the terrestrial surface. In the United States, people who travel above a height of 80.5 km (50 statute miles) are selected astronauts. An altitude of 120 km (400,000 ft) marks the boundary where atmospheric property becomes obvious during re-entry. The Kármán line, at 100 km (328,000 ft), is also often regarded as the boundary between atmosphere and outer space.

Dance

Dance means in Old French dancier, perhaps from Frankish generally refers to human movement also used as a form of expression or presented in a social, spiritual or performance setting.

Dance also is used to explain methods of non-verbal communication (see body language) between humans or animals (bee dance, mating dance), motion in inanimate objects (the leaves danced in the wind), and certain musical forms or genres.

Choreography is the art of making dances, and the human being who does this is called a choreographer.

Definitions of what constitutes dance are dependent on social, cultural, visual, artistic and moral constraints and variety from functional movement (such as folk dance) to codified, virtuoso techniques such as ballet. Dance disciplines live in sports such as gymnastics, figure skating, and synchronized swimming and martial arts kata are often compare to dance.

Leaf vegetable

Vegetable is a cookery term which usually refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat random and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are in general considered vegetables. Mushrooms, though belong to the biological kingdom fungi, and are also commonly considered vegetables. In common, vegetables are consideration of as being savory, and not sweet, although there are many exceptions. Nuts, grains, herbs, spices and culinary fruits are usually not exact vegetables.

Harrington jacket

A Harrington jacket is a type of tiny, lightweight jacket, made of cotton, polyester, wool or suede — generally with a tartan or check-patterned lining.

The initial Harrington-style jackets were made by British clothing company, Baracuta, in the 1930s; the company is still making the same model, the G9. This style of jacket got the nickname Harrington because it was worn by the personality Rodney Harrington (played by Ryan O'Neal) in the 1960s television program Peyton Place; John Simmons, who opened 'The Ivy Shop', Richmond, London, claims to have coined this explanation.

Electric

The first electric cars were built in the early 1880s shortly before interior combustion powered cars appeared. For a period of time electrics were measured superior due to the silent nature of electric motors compare to the very loud noise of the gasoline engine. This supreme benefit was removed with Hiram Percy Maxim's invention of the muffler in 1897. Thereafter internal combustion powered cars had two critical advantages:
1) Long range and 2) high specific energy (far lower weight of petrol fuel against weight of batteries). The building of battery electric vehicles that could competitor internal combustion models had to wait for the introduction of modern semiconductor controls and enhanced batteries. Because they can deliver a high torque at low revolutions electric cars do not need such a complex drive train and transmission as internal combustion powered cars. Some post-2000 electric car designs are able to speed up from 0-60 mph (96 km/hour) in 4.0 seconds with a top speed around 130 mph (210 km/h). Others have a variety of 250 miles (400 km) on the EPA highway cycle requiring 3-1/2 hours to completely charge. Equivalent fuel efficiency to internal combustion is not well defined but some press reports give it at approximately 135 mpg.

Ganesha drinking milk again

NEW DELHI: In a re-run of the September 1995 frenzy when Ganesha statues were said to be drinking milk offered to them, devotees apparently thronged temples on Sunday night, making alike claims. This time, nevertheless, all idols were reported to be drinking milk.

This followed some reports received from additional parts of the country, particularly UP, earlier in the day. Shiv Mandir in Uttam Nagar and Shri Ram temple on Aruna Asaf Ali Marg in New Delhi witnessed a huge rush.

Said a Ram temple priest, "People observed that Ganesha is drinking milk around 8 pm, after which the word spread and thousands thronged the temple to try it out. Lord Ganesha drank milk from all. The crowd remained till around 11 pm."

Rationalists have explained the scientific cause behind this phenomenon, including surface tension, but faith and superstition always hit back. Said a devotee, "It was amazing.”
