    Three diatom species were sent to the International Space Station, together with the huge (6 mm length) diatoms of Antarctica and the exclusive colonial diatom, Bacillaria paradoxa.

  3. Ochrophyte - Wikipedia

    en.wikipedia.org/wiki/Ochrophyte

    Within the diatoms (Bacillariophyta), harmful effects can be due to physical damage or to toxin production. Centric diatoms like Chaetoceros live as colonial chains of cells with long spines (setae) that can clog fish gills, causing their death.

  4. Insect physiology - Wikipedia

    en.wikipedia.org/wiki/Insect_physiology

    An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...

  5. Taxonomy of diatoms - Wikipedia

    en.wikipedia.org/wiki/Taxonomy_of_diatoms

    For many years the diatoms—treated either as a class (Bacillariophyceae) or a phylum (Bacillariophyta)—were divided into just 2 orders, corresponding to the centric and the pennate diatoms (Centrales and Pennales; alternative names Biddulphiales and Bacillariales, as used e.g. in Lee, 1989).

  6. Osteophyte - Wikipedia

    en.wikipedia.org/wiki/Osteophyte

    Osteophyte formation has classically been related to sequential and consequential changes in such processes. Often osteophytes form in osteoarthritic joints as a result of damage and wear from inflammation. Calcification and new bone formation can also occur in response to mechanical damage in joints. [5]

  7. Frustule - Wikipedia

    en.wikipedia.org/wiki/Frustule

    Scanning electron micrographs of frustules from some algae species - scale bar = 10 micrometres in a,c and d and 20 micrometres in b. A frustule is the hard and porous cell wall or external layer of diatoms.

  8. Knuckle-walking - Wikipedia

    en.wikipedia.org/wiki/Knuckle-walking

    Platypus fingers have webbing that extend past the fingers to aid in swimming, thus knuckle-walking is used to prevent stumbling. Gorillas move around by knuckle-walking, although they sometimes walk bipedally for short distances while carrying food or in defensive situations.
