在Stella、Globobulimina pacifica、Buliminella tenuata、Boliodaragentea、Loxostomum pseudobeyrichi、Cassidulinoides cornuta和Boliodarcf. subunculata，指出O2吸收的孔功能。线粒体与气孔的关系在B中最为明显。tenuata、细叶拟步行虫B. argentea和L. pseudobeyrichi采集自深水、低氧环境。双盖蕨通过其气孔容易吸收14CO2，表明其气孔功能与共生体的光合作用有关。14C标记的葡萄糖在2小时的暴露时间内没有以可追踪的量通过孔。
Clusters of mitochondria were observed close to the inner end of the pores in Nonionella stella, Globobulimina pacifica, Buliminella tenuata, Bolivina argentea, Loxostomum pseudobeyrichi, Cassidulinoides cornuta and Bolivina cf. subexcavata, pointing to a pore function of O2 uptake. The relationship between mitochondria and pores is most distinct in B. tenuata, B. argentea and L. pseudobeyrichi collected from a deepwater, low O2 environment. Amphistegina lobifera Larsen readily took up 14CO2 through its pores, indicating a pore function related to the photosynthetic activities of its symbionts. 14C-labeled glucose did not pass through the pores in traceable amounts during a 2 h exposure time.
