The Dinosaurs of Santa Monica is a 1989 topiary sculpture series installed along the Third Street Promenade in Santa Monica, California.Featured are six dinosaurs made of stainless steel, copper, and plant materials: a Triceratops measuring approximately 5 x 14 x 3 ft., a Stegosaurus measuring approximately 6 x 14 x 3 ft., an Apatosaurus measuring approximately 12 ft. x 34 ft. x 4 ft. 4 in., a ...
From these conclusions about plants and animals, two of the three tenets of cell theory were postulated. 1. All living organisms are composed of one or more cells 2. The cell is the most basic unit of life. Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert ...
The acid-growth hypothesis is a theory that explains the expansion dynamics of cells and organs in plants. It was originally proposed by Achim Hager and Robert Cleland in 1971. [1] [2] They hypothesized that the naturally occurring plant hormone, auxin (indole-3-acetic acid, IAA), induces H + proton extrusion into the apoplast.
In mathematics, and specifically in topology, a CW complex (also cellular complex or cell complex) is a topological space that is built by gluing together topological balls (so-called cells) of different dimensions in specific ways.
In evolutionary biology, the term cellularization (cellularisation) has been used in theories to explain the evolution of cells, for instance in the pre-cell theory, [1] [2] [3] dealing with the evolution of the first cells on this planet, and in the syncytial theory [4] attempting to explain the origin of Metazoa from unicellular organisms.
Forster Block, 122–128 S. Main St. (post-1890 numbering), 22–28 S. Main St. (per-1890 numbering), was a two-story building built in the early 1880s, five doors south of the Grand Opera House. It housed a coffee house of the Women's Christian Temperance Union at #26, heavily damaged in an 1885 fire, and a saddlery.
Virchow's cellular theory was encapsulated in the epigram Omnis cellula e cellula ("all cells (come) from cells"), which he published in 1855. [ 9 ] [ 22 ] [ 32 ] (The epigram was actually coined by François-Vincent Raspail , but popularized by Virchow.) [ 33 ] It is a rejection of the concept of spontaneous generation, which held that ...
A 3D cell culture is an artificially created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions. Unlike 2D environments (e.g. a Petri dish), a 3D cell culture allows cells in vitro to grow in all directions, similar to how they would in vivo. [1]
