Sporangium
Definition:
(n.) A spore case in the cryptogamous plants, as in ferns, etc.
Example Sentences:
(1) This "belt," usually first observed toward the center of the sporangium, developed without changing thickness or appearance over the surface of the forespore.
(2) It is proposed that simple, eucarpic, monocentric chytrids which discharge zoospores following dissolution of the sporangium wall evolved into multipapilliate species of Rhizophydium and 2 lines of evolution from these species are documented with examples.
(3) The cytoplasmic sporangium cleavage is brought about by the fusion of flagellar sheaths and cleavage vesicles.
(4) The mature resting sporangium (RS) wall of Coelomomyces dodgei (Chytridiomycetes; Blastocladiales) consists of three principal layers: (I) an outer pigmented layer (1.8-2.2 microns) that contains polysaccharide, (II) a middle electron translucent layer (1.3-1.6 microns) comparatively free of polysaccharide, and (III) an inner layer (125 nm) rich in polysaccharide that surrounds the meiospores.
