Morphogenesis

... organism and which give rise to the characteristic forms of tissues , organs and overall body anatomy . In the human embryo, the change from a cluster of nearly identical cells at the blastula stage to a post- gastrulation embryo with structured tissues and organs is controlled by the ...

Homeobox

... than a single homeodomain protein. A particular subgroup of homeobox genes are the Hox genes , which are found in a special gene cluster, the HOX cluster . Hox genes function in patterning the body axis. Thus, by providing the identity of particular body regions, Hox genes determine where limbs and ...

Leaf

... of four rotated 45, etc). Note: opposite leaves may appear whorled near the tip of the stem. Rosulate — leaves form a rosette ( = a cluster of leaves growing in crowded circles from a common center). Leaves of the Norway Spruce ( Picea abies ) are needle-shaped and the ...

Lipid

... the polar, aqueous environment, while the hydrophobic tails tend to minimize their contact with water. The nonpolar tails of lipids ( U ) tend to cluster together, forming a lipid bilayer (1) or a micelle (2). The polar heads ( P ) face the aqueous environment. Micelles form when single-tailed ...

Nephron

... Nephron of the kidney A nephron is the basic structural and functional unit of the kidney . It is a tiny tubule consisting of a cluster of capillaries called the glomerulus , surrounded by a hollow bulb known as Bowman's capsule . Bowman's capsule leads into a long, convoluted ...

Type I photosystems use ferredoxin like iron-sulfur cluster proteins as terminal electron acceptors, while type II photosystems ultimately shuffle electrons to a quinone terminal electron acceptor. ...
