Fissuring
Splitting so as to cause deep longitudinal cracks.
-
Fissured
Cracked with deep splits (usually used of bark). With many fissures or furrows, occurring on trees with persistent bark and caused by the growth in diameter of the underlying wood, resulting in stretching of the bark layer. Each tree species has its characteristic pattern of bark behaviour.
-
Fssure
Deep and narrow split.
-
Fission
In physics, disintegration or splitting of an atom. The act of dividing into two or more parts. Splitting, as in the asexual formation of new bacterial or protozoan cells or in the splitting of an atomic nucleus, with the release of energy. A method of asexual reproduction in which the body of a protozoan or…
-
Fissile
Easily splitting, tending to split. Able to split or be split.
-
Fimbriolate
Bordered by very fine and very slender hairs or hair-like processes.
-
Fimbrillate
Like fimbriate, but the marginal processes very small; (In Compositae/Asteraceae) very small processes between the florets on the receptacle.
-
Fimbriate
(Of margins) bordered by rather broad hair-like processes (as distinct from hairs or slender spines), fringed. As in ciliate, but coarser and longer. Fringed, the hairs coarser than in ciliate.
-
Fimbriae
Slender, hair-like processes. Minute appendages to bacteria, of flagellar type but much smaller (seen only by electron microscopy) and very much greater in number than flagella, one organism bearing several hundreds. Fimbriae do not confer motility, but possess antigenic and haemag-glutinating properties. They occur principally among the enterobacteria, where they may complicate the performance of…

Filter bridge
(In plant distribution) barrier that some but not all organisms can cross, such as a strait, mountain or different climate.
