Capsule

 

in biology:

  1. In animals and man, the membrane surrounding various organs and their parts (for example, the kidney, liver, or joint capsules) and also pathological formations (parasites that have implanted themselves in tissue, necrotic masses, foreign bodies). A capsule is composed primarily of fibrous connective tissue and sometimes of adipose cellular tissue.
  2. The gelatinous layer around a cell characteristic of the capsulated bacteria, formed from macromolecular substances produced by these microorganisms[11–1083^]

Capsule

 

(1) A dry dehiscent fruit with many seeds (sometimes with one seed), formed of two or several carpels. Capsules dehisce by means of a lid (plantain, henbane), tiny holes (poppy, bellflower), denticles on top of the capsule (primrose, pinks), or longitudinal splits (valves) along the septum (tobacco, hellebore) or along the valves (tulip, lily, hyacinth).

(2) The spore-bearing part of the sporangium of mosses. These capsules are either cylindrical or spherical.
