TULIPS FLOWER - report text

Tulips are spring-blooming perennials that grow from bulbs. Depending on the species, tulip plants can grow as short as 4 inches (10 cm) or as high as 28 inches (71 cm). The tulip's large flowers usually bloom on scapes. Most tulips produce only one flower per stem, but a few species bear multiple flowers on their scapes. The showy, generally cup- or star-shaped tulip flower has three petals and three sepals, which are often termed tepals because they are nearly identical. These six tepals are often marked near the bases with darker colorings. Tulip flowers come in a wide variety of colors, except pure blue. Tulip stems have few leaves. Plants typically have 2 to 6 leaves, with some species having up to 12. The tulip's leaf is strap-shaped, with a waxy coating, and leaves are alternately arranged on the stem.

During the Ottoman Empire, the tulip became very popular in Ottoman territories and was seen as a symbol of abundance. In fact, the era during which the Ottoman Empire was wealthiest is often called the Tulip era or Lale Devri in Turkish. In classic and modern Persian literature, sp ecial attention has been given to these beautiful flowers, and in recent times, tulips have featured in the poems of Simin Behbahani. However, the tulip was a topic for Persian poets as far back as the thirteenth century.

The Black Tulip is the title of a historical romance by the French author Alexandre Dumas, père. The story takes place in the Dutch city of Haarlem, where a reward is offered to the first grower who can produce a truly black tulip.

Every spring, there are several tulip festivals in North America, including the Tulip Time Festival in Holland, Michigan, the Skagit Valley Tulip Festival in Skagit Valley, Washington, the Tulip Time Festival in Orange City and Pella, Iowa, and the Canadian Tulip Festival in Ottawa, Canada. Tulips are now also popular in Australia and several festivals are held during the Southern Hemisphere's spring.

Mangrove trees

A mangrove is a tropical marine tree. Mangroves have special aerial roots and salt-filtering tap roots which enable them to thrive in brackish water. Brackish water is salty but not as salty as sea water. Mangrove trees are commonly planted and found in coastal areas.

            Mangroves can serve as walls of protection for natural disaster in coastal area like tsunami. Healthy mangrove forests had helped save lives in the Asia disaster tsunami and people tended to respect these natural barriers even more, especially after the tsunami.

There are several species of mangrove tree found all over the world. Some prefer more salinity, while others like to be very-close to a large fresh water source such as river. Some prefer areas that are sheltered from waves. Some species have their roots covered with sea water every day during high tide. Other species grow on dry land but are still part of the ecosystem. The times of India reported that rare species of mangrove had been found and was also known as the looking-glass tree, probably because the leaves are silver-coated.

Mangroves need to keep their trunk and leave above the surface of the water. Yet they also need to be firmly attached to the ground so they are not moved by waves.
Any part of root that appears above the water flows oxygen to the plant under water surface. as the soil begin to build up, these roots procedure additional roots that become embedded in the soil.
