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 ...
Specifically, if X and Y are CW complexes, then one can form a CW complex X × Y in which each cell is a product of a cell in X and a cell in Y, endowed with the weak topology. The underlying set of X × Y is then the Cartesian product of X and Y , as expected.
Goethe's foliar theory was formulated in the 18th century and it suggests that the constituent parts of a flower are structurally modified leaves, which are functionally specialized for reproduction or protection. The theory was first published in 1790 in the essay "Metamorphosis of Plants" ("Versuch die Metamorphose der Pflanzen zu erklären").
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.
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.
Parenchyma is a versatile ground tissue that generally constitutes the "filler" tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
