Examples of morphology in the following topics:

  • Bacterial Differentiation

    • Several bacteria alter their morphology in response to the types and concentrations of external compounds.
    • Bacterial morphological plasticity refers to evolutionary changes in the shape and size of bacterial cells.
    • As bacteria evolve, morphological changes occur to maintain the consistency of the cell.
    • Nutritional stress can change bacterial morphology.
    • However, it returns to a regular rod-like morphology when adding back these nutrients.

  • Morphologically Unusual Proteobacteria

    • The two main groups of morphologically unusual proteobacteria include spirillum and prosthecate bacteria.
    • Two main groups of morphologically unusual proteobacteria include spirillum and prosthecate bacteria.

  • General Morphology

    • Viruses display a wide diversity of shapes and sizes, called morphologies.
    • In general, there are five main morphological virus types :
    • The capsid is made from proteins encoded by the viral genome and its shape serves as the basis for morphological distinction.

  • Viruses of Archaea

    • The morphology and the genome appear to be unique.
    • Most have head-tail morphologies and linear double-stranded DNA genomes.
    • Other morphologies have also been described including spindle shaped, rod shaped, filamentous, icosahedral, and spherical.
    • Additional morphological types may exist.
    • The morphology and the genome appear to be unique.

  • Phenotypic Analysis

    • Bacteria, algae, and fungi have been identified in amber that is 220 million years old, which shows that the morphology of microorganisms has changed little since the Triassic period.
    • Some of the early phylogenetic trees of the prokaryote world were morphology-based.
    • There are some basic differences between Bacteria, Archaea, and Eukaryotes in cell morphology and structure which aid in phenotypic classification and identification:
    • Due to lateral gene transfer, some closely related bacteria can have very different morphologies and metabolisms.
    • Basic morphological differences between bacteria.

  • Class Scyphozoa

    • Scyphozoans are free-swimming, polymorphic, dioecious, and carnivorous cnidarians with a prominent medusa morphology.
    • Scyphozoans display a characteristic bell-like morphology.

  • Classification of Receptors by Stimulus

    • Somatic sensory receptors near the surface of the skin can usually be divided into two groups based on morphology:
    • Sensory receptor cells differ in terms of morphology, location, and stimulus.

  • Structure and Function of the Muscular System

    • The muscular system controls numerous functions, which is possible with the significant differentiation of muscle tissue morphology and ability.
    • Muscle tissue can be classified functionally as voluntary or involuntary and morphologically as striated or non-striated.
    • Morphologically skeletal myocytes are elongated and tubular and appear striated with multiple peripheral nuclei.

  • Morphology of Sponges

    • The morphology of the simplest sponges takes the shape of a cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder .
    • The gel-like consistency of mesohyl acts as an endoskeleton, maintaining the tubular morphology of sponges.

  • Phylum Nemertea

    • Because of their contractility, they can change their morphological presentation in response to environmental cues.
    • Animals in phylum Nemertea also show a flattened morphology: they are flat from front to back, like a flattened tube.
    • This larval form, characteristically shaped like a deerstalker cap, devours tissues from the young worm for survival before metamorphosing into the adult-like morphology.
