n a small hole in an igneous rock that created by gasses escaping from the rock as it cools and solidifies
a small cavity in an aphanitic (fine-grained) or glassy igneous rock, formed by the expansion of a bubble of gas or steam during the solidification of the rock
1: Enlarged structure at the end of a coniodiophore or sporangiophore In Aspergillus spp it bears the phialides, which in turn bear the conidia
A small bladder-like sac used by arbuscular mycorrhizal fungi for carbon storage
A small bladderlike body in the substance of vegetable, or upon the surface of a leaf
{i} bladder or bladder-like cavity; small blister filled with fluid; sac in the body, cyst (especially one filled with fluid); cavity formed in a rock by a pocket of gas that is trapped during the rock's formation (Geology)
A circumscribed cavity in the epidermis filled with serum, plasma, or blood and covered by a thin layer of epidermis that is greatly elevated above the surface
A small, and more or less circular, elevation of the cuticle, containing a clear watery fluid
A bubble-shaped cavity in lava, formed by the expansion of entrapped gases Such cavities may later become filled with material deposited from solution Vesicular basalt (bubbly basalt lava) is basaltic lava containing numerous openings, generally ellipsoidal or cylindrical in shape, formed by the expansion of dissolved gases in the molten rock
One of two simple tubular glands located behind the male urinary bladder, responsible for the production of about sixty percent of the fluid that ultimately becomes semen
Either of a pair of pouchlike glands situated on each side of the male urinary bladder that secrete seminal fluid and nourish and promote the movement of spermatozoa through the urethra
In solidified lavas this is a term used to describe 'frozen' gas bubbles When lavas are erupted, the drop in pressure allows gases to separate and form bubbles in the molten rock If the lava solidifies before the gas bubbles escape the 'bubbles' or vesicles are preserved in the rock When vesicles are later in filled with a mineral they are called amygdales
Small hollow balls of membrane or lipid Amoeboid cells contain many vesicles which exchange with membrane due to endocytosis and exocytosis Vesicles can also be made in the test tube Letters W to Z
