proloculus मीनिंग इन हिंदी

उदाहरण वाक्य

1. Tests are non septate and consist of a single chamber following the proloculus.
2. The proloculus is large, followed by seven to nine gradually enlarging volutions, coiled around a straight to irregular axis.
3. Tests of the Spirillinata consist typically of a proloculus followed by an undivided planospirally or trochospirally wound tubular chamber such that the test is either planar or conical.
4. Ontogeny goes through an early quinqueloculine stage immediately following the proloculus, followed in sequence by triloculine and biloculine stages and finally to an adult stage with completely enveloping chambes.
5. Smaller megalospheric tests may be fan-shaped or kidney-shaped to discoidal with breadths to slightly over 2 mm and a constant thickness equal to that of the proloculus.
6. The included genera are characterized by asymmetrical, semi-involute to partially evolute, aragonitic tests consisting of an undivided planispiral or trochospiral tubular chamber wound about the proloculus, or initial chamber.
7. Hemigordiopsids are characterized by tests in which the proloculus, or first chamber, is followed by an undivided tubular second chamber that is streptospirally coiled, ( like a ball of string ), at least in early stage, later may be planispiral, involute, or evolute.
8. The "'Hirsutospirellidae "', established for the Upper Triassic genus " Hirsutospirella ", are a family of Foraminifera within the Involutinida that produced calcareous tests with a proloculus followed by an undivided trochospirally enrolled tubular second chamber, in which the spiral side has prominent spinelike protrusions and umbilical side has a shallow umbilical filling.
9. Irregular coiling is found in the first volutions in the microspheric forms of most genera, indicating a close relationship with the Miliolidae . " Alveolinella " is an exception as the proloculus in the microspheric form is perforate and the first volutions are peneroplid in character, suggesting it, " Alveolinella ", may have a different origin than the other alveolinids.
