#cell morphology

• Amoeba — A primitive microscopic single-celled eukaryotic organism from the protozoan phylum (class Rhizopoda / Sarcodina), characterized by a flexible cellular structure lacking a rigid wall, which constantly changes its shape by emitting pseudopodia (false feet) used for locomotion and capturing food via phagocytosis.
• Amoebiform — Having the shape, appearance, or structural behavior of an amoeba; a morphological term used to describe cells, microbial colonies, or lower organisms that exhibit irregular, changing outlines and the capacity to emit pseudopodia.
• Amoebocyte — A free migratory cell with amoeboid movements, found in the blood, hemolymph, or interstitial tissues of many invertebrate animals (such as sponges, coelenterates, or mollusks); it features a flexible structure and performs fundamental functions of intracellular digestion, nutrient transport, excretion, and immune defense via phagocytosis.
• Amoeboid — Resembling an amoeba in shape, structure, or motor behavior; a term used especially to describe cells or microorganisms lacking a rigid wall, capable of constantly changing their cytoplasmic profile and moving by means of pseudopodia.
• Amoebiform — Having the shape or appearance of an amoeba; characterized by an irregular, asymmetrical, and time-variable geometric structure equipped with flexible cytoplasmic extensions. In biology, the term describes the morphological state of certain free cells or microorganisms that constantly modify their outer contour for locomotion or phagocytosis.
