Each level in the hierarchy can be described by its lower levels. For example, the organism may be described at any of its component levels, including the atomic, molecular, cellular, histological (tissue), organ and organ system levels. Furthermore, at every level of the hierarchy, new functions necessary for the control of life appear.
At a tissue level, ignoring the means of control, morphogenesis arises because of cellular proliferation and motility. [9] Morphogenesis also involves changes in the cellular structure [10] or how cells interact in tissues. These changes can result in tissue elongation, thinning, folding, invasion or separation of one tissue into distinct layers.

The levels concept is an intellectual framework for structuring reality. It arranges all entities, structures, and processes in the universe, or in a certain field of study, into a hierarchy, typically based on how complex their organization is. When arranged this way, each entity is three things at the same time: It is made up of parts from ...
The BRENDA tissue ontology (BTO) represents a comprehensive structured encyclopedia. It provides terms, classifications, and definitions of tissues , organs , anatomical structures, plant parts, cell cultures , cell types , and cell lines of organisms from all taxonomic groups ( animals , plants , fungi , protozoon ) as enzyme sources.
Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1] In the medical context, outside of specialized branches of biomedicine , morphological adaptations are not always referenced to the fundamental cellular level, but are observed and assessed at the level of tissues and organs .
The human cerebral cortex divided into Brodmann areas on the basis of cytoarchitecture.. Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system's tissues under the microscope.
