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 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 .
Like all the soap plants, Chlorogalum pomeridianum is a perennial that grows from a bulb, which is brown, between 7 and 15 cm in diameter, slightly elongated, and covered in thick, coarse fibers. The leaves grow from the base of the plant, and can be from 20 to 70 cm long and 6 to 25 mm wide. [ 1 ]
Unlike most other eukaryotes, ciliates have two different sorts of nuclei: a tiny, diploid micronucleus (the "generative nucleus", which carries the germline of the cell), and a large, ampliploid macronucleus (the "vegetative nucleus", which takes care of general cell regulation, expressing the phenotype of the organism).
Fused protoplast (left) with chloroplasts (from a leaf cell) and coloured vacuole (from a petal) Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid.

Although plants produce numerous copies of the same organ during their lives, not all copies of a particular organ will be identical. There is variation among the parts of a mature plant resulting from the relative position where the organ is produced. For example, along a new branch the leaves may vary in a consistent pattern along the branch.
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus.
Lacking photosynthetic pigments, leucoplasts are located in non-photosynthetic tissues of plants, such as roots, bulbs and seeds. They may be specialized for bulk storage of starch , lipid or protein and are then known as amyloplasts , elaioplasts , or proteinoplasts (also called aleuroplasts) respectively.
