A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are present in most prokaryotes, in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.
Mary I, also known as Mary Tudor, and as "Bloody Mary" by her Protestant opponents, was Queen of England and Ireland from July 1553 until her death in 1558. She is best known for her vigorous attempt to reverse the English Reformation, which had begun during the reign of her father, Henry VIII. Her attempt to restore to the church the property confiscated in the previous two reigns was largely thwarted by parliament, but during her five-year reign, Mary had over 280 religious dissenters burned at the stake in the Marian persecutions.
Thomas Wright "Fats" Waller was an American jazz pianist, organist, composer, violinist, singer, and comedic entertainer. His innovations in the Harlem stride style laid the groundwork for modern jazz piano. His best-known compositions, "Ain't Misbehavin'" and "Honeysuckle Rose", were inducted into the Grammy Hall of Fame in 1984 and 1999. Waller copyrighted over 400 songs, many of them co-written with his closest collaborator, Andy Razaf. Razaf described his partner as "the soul of melody... a man who made the piano sing... both big in body and in mind... known for his generosity... a bubbling bundle of joy". It is possible financial circumstances caused him to compose many more popular songs and sell them to other performers.
Charlotte Perkins Gilman, also known as Charlotte Perkins Stetson, her first married name, was a prominent American humanist, novelist, writer of short stories, poetry and nonfiction, and a lecturer for social reform. She was a utopian feminist and served as a role model for future generations of feminists because of her unorthodox concepts and lifestyle. She has been inducted into the National Women's Hall of Fame. Her best remembered work today is her semi-autobiographical short story "The Yellow Wallpaper", which she wrote after a severe bout of postpartum psychosis.
The Wall is the eleventh studio album by the English rock band Pink Floyd, released on 30 November 1979 by Harvest and Columbia Records. It is a rock opera that explores Pink, a jaded rock star whose eventual self-imposed isolation from society forms a figurative wall. The album was a commercial success, topping the US charts for 15 weeks, and reaching number three in the UK. It initially received mixed reviews from critics, many of whom found it overblown and pretentious, but later received accolades as one of the greatest albums of all time.
Iron Maiden are an English heavy metal band formed in Leyton, East London, in 1975 by bassist and primary songwriter Steve Harris. The band's discography has grown to 40 albums, including 16 studio albums, 13 live albums, four EPs, and seven compilations.
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep.
A façade or facade is generally the front part of exterior of a building. It is a loan word from the French façade, which means "frontage" or "face".
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England.
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian parapetto. The German equivalent Brüstung has the same meaning. Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling.
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of the roof structures that lack adequate bracing.
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. A gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roofs do not have a gable. One common type of roof with gables, the gable roof, is named after its prominent gables.
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems.
Rubble is broken stone, of irregular size, shape and texture; undressed especially as a filling-in. Rubble naturally found in the soil is known also as 'brash'. Where present, it becomes more noticeable when the land is ploughed or worked.

Pink Floyd were an English rock band formed in London in 1965. Gaining an early following as one of the first British psychedelic groups, they were distinguished for their extended compositions, sonic experimentation, philosophical lyrics and elaborate live shows, and became a leading band of the progressive rock genre.
The Great Wall of China is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined together by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties have built and maintained multiple stretches of border walls. The most well-known sections of the wall were built by the Ming dynasty (1368–1644).
Hadrian's Wall, also known as the Roman Wall, Picts' Wall, or Vallum Hadriani in Latin, is a former defensive fortification of the Roman province of Britannia, begun in AD 122 in the reign of the emperor Hadrian. Running "from Wallsend on the River Tyne in the east to Bowness-on-Solway in the west", the Wall covered the whole width of the island, as Jarrett A. Lobell says. In addition to the wall's defensive military role, its gates may have been customs posts.
A curtain wall is a defensive wall between two towers (bastions) of a castle, fortress, or town.
