The process whose specific outcome is the progression of the embryo over time, from zygote formation to the end of seed dormancy. An example of this process is found in Arabidopsis thaliana.

Any process that mediates the adoption of a specific fate by a cell.

Any process that modulates the frequency, rate or extent of the physical partitioning and separation of a cell into daughter cells.

The process whose specific outcome is the progression of the plant epidermis over time, from its formation to the mature structure.

The process in which the polarity of a plant organ axis is specified.

Any process that modulates the frequency, rate or extent of root morphogenesis.

Any process that modulates the frequency, rate or extent of root development.

The directed movement of water (H2O) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The process whose specific outcome is the progression of the embryo sac over time, from its formation to the mature structure. The process begins with the meiosis of the megasporocyte to form four haploid megaspores. Three of the megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center. The two polar nuclei fuse resulting in a mononucleate diploid endosperm mother cell. The three antipodal cells degenerate.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to the organism.

Any process involved in the maintenance of an internal steady state of water within an organism or cell.

The process in which a relatively unspecialized cell acquires the specialized features of an endoderm cell, a cell of the inner of the three germ layers of the embryo.

The directed movement of a protein to a specific location.

Any process involved in the maintenance of an internal steady state of potassium ions within an organism or cell.

Any process that modulates the frequency, rate or extent of endodermal cell differentiation.

Region of plant cell wall specialised to act as a seal to prevent back leakage of secreted material (analogous to tight junction between epithelial cells). Found particularly where root parenchymal cells secrete solutes into xylem vessels. The barrier is composed of suberin; a fatty substance, containing long chain fatty acids and fatty esters, also found in the cell walls of cork cells (phellem) in higher plants.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
