The chemical reactions and pathways resulting in the breakdown of cytokinins, a class of adenine-derived compounds that can function in plants as plant growth regulators.

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

The process in which the anatomical structures of the stomatal complex are generated and organized. The stomatal complex is the stomatal guard cells and their associated epidermal cells.

A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The volume enclosed by the membranes of the endoplasmic reticulum.
