Andrew Dice Clay (born Andrew Clay Silverstein; September 29, 1957) [1] is an American stand-up comedian and actor. He rose to prominence in the late 1980s with a brash, deliberately offensive persona known as "The Diceman".
Club cells, also known as bronchiolar exocrine cells, [1] are low columnar/cuboidal cells with short microvilli, found in the small airways (bronchioles) of the lungs. [2] They were formerly known as Clara cells. Club cells are found in the ciliated simple epithelium. These cells may secrete glycosaminoglycans to protect
3D rendering of centrioles showing the triplets. In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. [1] Centrioles are found in most eukaryotic cells, but are not present in conifers (), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.
Another group suggests that primitive cells might have formed inside inorganic clay microcompartments, which can provide an ideal container for the synthesis and compartmentalization of complex organic molecules. [68] Clay-armored bubbles form naturally when particles of montmorillonite clay collect on the outer surface of air bubbles under ...
The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here. [7]
The centrosome is copied only once per cell cycle, so that each daughter cell inherits one centrosome, containing two structures called centrioles. The centrosome replicates during the S phase of the cell cycle. During the prophase in the process of cell division called mitosis, the centrosomes migrate to opposite poles of the cell. The mitotic ...

This is the only type of xylem found in the earliest vascular plants, and this type of cell continues to be found in the protoxylem (first-formed xylem) of all living groups of vascular plants. Several groups of plants later developed pitted tracheid cells independently through convergent evolution .
