Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

Any process that modulates the surface configuration of a cell.

The process whose specific outcome is the progression of the aggregate over time, from its formation to the point when a slug is formed. Aggregate development begins in response to starvation and continues by the chemoattractant-mediated movement of cells toward each other. The aggregate is a multicellular structure that gives rise to the slug.

The assembly of a pseudopodium by rearrangement of the actin cytoskeleton and overlying membrane.

Any process involved in the controlled self-propelled movement of a cell that results in translocation of the cell from one place to another.

Any process that stops, prevents, or reduces the frequency, rate or extent of phagocytosis.

The assembly of actin filament bundles; actin filaments are on the same axis but may be oriented with the same or opposite polarities and may be packed with different levels of tightness.

A process that is carried out at the cellular level which results in the arrangement of constituent parts of a phagosome within a cell. Phagosome maturation begins with endocytosis and formation of the early phagosome and ends with the formation of the hybrid organelle, the phagolysosome.

The assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following mitotic cytokinesis. The progeny cells that form a division septum are not able to exchange intracellular material.

Any actomyosin contractile ring contraction that is involved in mitotic cell cycle.

A cell septum which forms as part of the division site and functions in the compartmentalization of a cell into two daughter cells at division. A division septum spans a cell and does not allow exchange of organelles or cytoplasm between compartments.

A cytoskeletal structure composed of actin filaments and myosin that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the spindle, i.e. the cell division plane. In animal cells, the contractile ring is located at the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms at the mother-bud neck before mitosis.

The external part of the cell wall and/or plasma membrane.

The portion of the actin cytoskeleton, comprising filamentous actin and associated proteins, that lies just beneath the plasma membrane.

A temporary protrusion or retractile process of a cell, associated with flowing movements of the protoplasm, and serving for locomotion and feeding.

The area of a motile cell closest to the direction of movement.

The eventual plane of cell division (also known as cell cleavage or cytokinesis) in a dividing cell. In Eukaryotes, the cleavage apparatus, composed of septin structures and the actomyosin contractile ring, forms along this plane, and the mitotic, or meiotic, spindle is aligned perpendicular to the division plane. In bacteria, the cell division site is generally located at mid-cell and is the site at which the cytoskeletal structure, the Z-ring, assembles.

A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.

The region directly beneath the plasma membrane at the cell tip. The cell tip is the region at either end of the longest axis of a cylindrical or elongated cell.

The region at the end of the longest axis of a cylindrical or elongated cell.

The tip or margin of the progressing circular lamella that engulfs a particle during phagocytosis. When the two lips of the cup fuse it is converted into a phagosome.

The region of the actomyosin ring in between the proximal layer and the actin filament layer. This region contains the accessory protein network, some actin filaments and connections between the proximal layer and the actin filament layer.
