foraminifera including stages of reproduction and which also facilitates recognition of rose Bengal-stained agglutinated species and, if not relevant for micropalaeontologcal study, at least shows which part of the Recent and fossil record is excluded from being recognized Planktonic foraminifera shell size is the result of various processes such as respiration, calcification, symbiont photosynthesis, and feeding. Temperature influences the rates of these processes differently among species (Burke et al. 2018 ; Lombard, Erez, et al., 2009 ; Weinkauf, Kunze, Waniek, & Kucera, 2016 ). The agamont is the asexual reproduction phase of the foraminifera; upon reaching adulthood, the protoplasm entirely vacates the test and divides its cytoplasm meiotically via multiple fission to form a number of haploid offspring.

The mode of reproduction in Foraminifera species is largely dependent on the species.

The earliest forms which appear in the fossil record (the allogromiine) have organic test walls or are simple agglutinated tubes. The term "agglutinated" refers to the tests formed from foreign particles "glued" together with a variety of cements.

Abundance of certain Foraminifera is  When asexual reproduction begins the cytoplasm of the test test, or shell, which means they! Where they can dissolve and absorb it are single-celled protists with   Flatworms are hermaphroditic. Individuals fight to be the male and inject sperm. The one that receives the sperm, serves as a female as her eggs get fertilized. Foraminifera, or forams for short, are single-celled organisms that live in the open ocean, along the coasts and in estuaries.

Based on the extensive literature on the reproductive cycle of foraminiferans and indirect evidence, it was found that each of the parent individuals of this species was a partner in a plastogamous pair, thus being a gamont, while their offspring were agamonts.
