The process in which the identity of a floral organ is maintained. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

The process whose specific outcome is the progression of the cotyledon over time, from its formation to the mature structure. The cotyledon is the modified leaf (seed leaf), found as part of the embryo in plant seeds. It is involved in either storage or absorption of food reserves. Dicotyledonous seeds contain two cotyledons, while monocotyledonous seeds contain only one. The cotyledons may appear above ground and show photosynthetic activity in the seedling.

The physiological and developmental changes that occur in a seed commencing with water uptake (imbibition) and terminating with the elongation of the embryonic axis.

Any process involved in the formation of branches in plant hair cells. An example of this process is found in Arabidopsis thaliana.

The process in which the structures of a hair cell (trichome) cell are generated and organized. This process occurs while the initially relatively unspecialized epidermal cell is acquiring the specialized features of a hair cell. An example of this process is found in Arabidopsis thaliana.

The process in which a relatively unspecialized cell acquires specialized features of a plant epidermal cell.

The series of events leading to chemical and structural alterations of an existing cellulose and pectin-containing cell wall that can result in loosening, increased extensibility or disassembly. An example of this is found in Arabidopsis thaliana.

The series of events causing chemical and structural alterations of an existing cellulose and pectin-containing cell wall that results in greater extensibility of the wall. An example of this is found in Arabidopsis thaliana.

The process in which a relatively unspecialized cell acquires specialized features of an epidermal cell, any of the cells making up the epidermis.

Any process involved in the formation of branches in plant hair cells. An example of this process is found in Arabidopsis thaliana.

The chemical reactions and pathways resulting in the formation of a cuticle, the outer layer of some animals and plants, which acts to prevent water loss.

The aggregation of the pigment anthocyanin in a particular location in a tissue, occurring in response to a UV light stimulus.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

The process whose specific outcome is the progression of the root over time, from its formation to the mature structure. The root is the water- and mineral-absorbing part of a plant which is usually underground, does not bear leaves, tends to grow downwards and is typically derived from the radicle of the embryo.

The process in which a relatively unspecialized cell acquires specialized features of a root hair cell.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
