The common names soap plant, soaproot and amole refer to the genus Chlorogalum. They are native to western North America , with some species in Oregon but they are mostly found in California . Common names of the genus and several species derive from their use as soap .
Examples include horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are laticiferous, i.e. they contain latex, a milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots.
The resulting mixture is known as soft soap [broken anchor], which serves as a precursor for hard soap production. After adding sodium chloride (a process known as salting out), the soap nucleus rises and separates. The water-soluble glycerin and unwanted fat residues remain in the solution (see also soap [broken anchor]).
The term Monera became well established in the 20s and 30s when to rightfully increase the importance of the difference between species with a nucleus and without. In 1925, Édouard Chatton divided all living organisms into two sections, Prokaryotes and Eukaryotes: the Kingdom Monera being the sole member of the Prokaryotes section. [23]
Nuclear genes (in the cell nucleus of a plant) encode the vast majority of plastid proteins; and the expression of nuclear and plastid genes is co-regulated to coordinate the development and differention of plastids. Many plastids, particularly those responsible for photosynthesis, possess numerous internal membrane layers.
Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability ...
Each plant cell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the center of the cell, surrounded by cytoplasm. Firm, small onions are best for microscopy.
The majority of the plant pathogenic species can be classified into four groups, although more exist. The Phytophthora group is a paraphyletic genus that causes diseases such as dieback , late blight in potatoes (the cause of the Great Famine of the 1840s that ravaged Ireland and other parts of Europe), [ 15 ] sudden oak death , rhododendron ...
