Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. While originally it included plant morphology, which is the description of the physical form and external structure of plants, since the mid-20th century the investigations of plant anatomy are considered a separate, distinct field, and plant anatomy refers to just the internal plant structures. Plant anatomy is now frequently investigated at the cellular level, and often involves the sectioning of tissues and microscopy.
Plant anatomy is often divided into the following categories:
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
Tea culture is defined by the way tea is made and consumed, by the way the people interact with tea, and by the aesthetics surrounding tea drinking, it includes aspects of: tea production, tea brewing, tea arts and ceremony, society, history, health, ethics, education, and communication and media issues.
Tea is commonly consumed at social events, and many cultures have created intricate formal ceremonies for these events. Western examples of these are afternoon tea and the tea party. Tea ceremonies, with its roots in the Chinese tea culture, differ among eastern countries, such as the Japanese or Korean tea ceremony. However, it may also differ in preparation, such as in Tibet, where tea is commonly brewed with salt and butter. Tea also plays an important role in some countries.
The Korean tea ceremony or darye is a traditional form of tea ceremony practiced in Korea. Darye literally refers to "etiquette for tea" or "day tea rite" and has been kept among Korean people for an over a thousand years. The chief element of the Korean tea ceremony is the ease and naturalness of enjoying tea within an easy formal setting.
Tea ceremonies are now being revived in Korea as a way to find relaxation and harmony in the fast-paced new Korean culture, and continuing in the long tradition of intangible Korean art.
