A developmental process in which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring.

The orientation of plant parts towards gravity.

The process that gives rise to a lateral root. This process pertains to the initial formation of a structure from unspecified parts. A lateral root primordium represents an organized group of cells derived from the root pericycle that will differentiate into a new root, as opposed to the initiation of the main root from the embryo proper.

A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle.

Coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

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 physiological and developmental changes that occur in a heterosporous plant pollen grain, beginning with hydration and terminating with the emergence of the pollen tube through the aperture.

Growth of pollen via tip extension of the intine wall.

Growth of pollen via tip extension of the intine wall.

The process of opening or closing of stomata, which is directly related to the stomatal conductance (measuring rate of passage of either water vapor or carbon dioxide (CO2) through stomata).

The chemical reactions and pathways involving phosphatidylinositol, any glycophospholipid in which a sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.

The process in which a protrusion or bulge is formed at the site of plant root hair outgrowth.

The process in which the root hair grows longer.

Localized growth of a plant root hair tip by extension of the cell wall.

Any process that modulates the frequency, rate or extent of establishment of cell polarity.

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

The region of the plasma membrane located at the apical end of the cell.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A tubular cell projection that is part of a pollen tube cell and extends from a pollen grain.
