Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell.

The reversible, non-sexual aggregation of single-celled organisms in suspension to form aggregates of many cells known as flocs.

A protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via the N4 atom of peptidyl-asparagine, the omega-N of arginine, or the N1' atom peptidyl-tryptophan.

Any process involved in the maintenance of an internal steady state of metal ions at the level of a cell.

The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

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.

Any process involved in maintaining the identity, size and shape of a meristem.

The final stages of microgametogenesis after the trinucleate stage has been reached resulting in viable pollen grains.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of phosphate.

Any process involved in the maintenance of an internal steady state of manganese ions at the level of a cell.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the fungal-type cell wall.

A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.

The attachment of a cell to a solid substrate, via cell adhesion molecules, during the formation of a biofilm composed of microorganisms of the same species.

A process in which microorganisms of the same species attach to and grow on an inanimate surface such as a rock or pipe, and produce extracellular polymers that facilitate attachment and matrix formation, resulting in an alteration in the phenotype of the organisms with respect to growth rate and gene transcription.

The process in which a cell becomes capable of differentiating autonomously into a stem cell regardless of its environment; upon determination, the cell fate cannot be reversed.

The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other

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

A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.

A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

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

The lipid bilayer surrounding the endoplasmic reticulum.

The lipid bilayer surrounding the endoplasmic reticulum.

The network of interconnected tubular and cisternal structures located at the convex side of the Golgi apparatus, which abuts the endoplasmic reticulum.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The component of the endoplasmic reticulum membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
