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 a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a cell wall. Includes biosynthesis of constituent macromolecules, such as proteins and polysaccharides, and those macromolecular modifications that are involved in synthesis or assembly of the cellular component. A cell wall is the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.

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.

A process in which microorganisms of the same species attach to and grow in or on a host species, and produce extracellular polymers that facilitate attachment and matrix formation, resulting in a change in the microorganisms' growth rate and gene transcription. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The chemical reactions and pathways resulting in the formation of beta-glucans, compounds composed of glucose residues linked by beta-D-glucosidic bonds, found in the walls of fungal cells.
