Chlorophyta Green algae on coastal rocks at Shihtiping in Taiwan. Chlorophyta is a division of green algae, informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it refers to a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms.

Enthesophyte An enthesophyte, consisting of calcification deposits within the Achilles tendon at its calcaneal insertion. The Achilles tendon is wider than normal, further suggesting inflammation. Enthesiophytes are abnormal bony projections at the attachment of a tendon or ligament. They are not to be confused with osteophytes, which are abnormal bony projections in joint spaces. Enthesiophytes and osteophytes are bone responses for stress.

- GENETIC CLASSIFICATION OF TEPHRA DEPOSITS. Pyroclastic airfall deposits (tephra) contain pyroclasts that are coarser near the vent (bomb and lapilli size) and become increasingly finer grained away from the vent (lapilli to ash size). The mafic to felsic composition of these deposits will vary with eruption type.he greater the explosivity, the greater the amount of fragmentation. Individual eruptive fragments are called pyroclasts (fire fragments). Tephra (Greek, for ash) is a generic term for any airborne pyroclastic accumulation.

Metaphysis The metaphysis (/mətˈæfᵻsᵻs/) is the narrow portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood and as it grows, it ossifies near the diaphysis and the epiphyses. The metaphysis may be divided anatomically into three components based on tissue content: a cartilaginous component (epiphyseal plate), a bony component (metaphysis) and a fibrous component surrounding the periphery of the plate.

What is the meaning of saprophytes? saprophytes is a word for the saprophytic organisms, and saprophytic is just a method of eating in which dead material is the choice of food.

Epiphysis The epiphysis (/ɛˈpɪfɨsɨs/) is the rounded end of a long bone, at its joint with adjacent bone(s).Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as subchondral bone. Another example of a pressure epiphysis is the head of the humerus which is part of the shoulder complex. 2  Traction epiphysis: The regions of the long bone which are non-articular, i.e. not involved in joint formation. 3  Unlike pressure epiphyses, these regions do not assist in weight transmission.

Recapitulation theory Haeckel formulated his theory as Ontogeny recapitulates phylogeny. The notion later became simply known as the recapitulation theory. Ontogeny is the growth (size change) and development (shape change) of an individual organism; phylogeny is the evolutionary history of a species.
