348 Epitheca: The larger half of a diatom frustule 上殼：硅藻硅質壁較大的一半。 Eyespot: A pigmented, light-sensitive organelle. 眼點: 一個含色素的感光細胞器。 Fultoportula (strutted process): A tubular process consisting of a central tube passing through the valve and two or more satellite pores that surround and support the central tube. The fultoportula appears as either a tube or a pore in the valve wall externally. These processes are found only in the centric diatoms. 支持突: 支持突有兩個或多個圍孔包圍并支持着一個壳面上中央管狀突起物。在殼 面外層，支持突呈管狀或小孔。支持突仅在一些中心硅藻又发现。 Girdle：The cincture of a diatom cell. 殼環：硅藻細胞的環面。 Girdle band: The overlapping band that joins the two valves of a diatom frustule together. A diatom frustule may have no, or many girdle bands. 殼環帶: 硅藻上下兩個殼面相連接重疊的地方。 硅藻硅質壁可能沒有或者很多殼 環帶。 Girdle view: Looking at the valves of a diatom from the side. It is the view of the frustule when the girdle is perpendicular to the observer. 殼環面觀: 從硅藻兩個殼面的側面方向觀看硅藻細胞，观察者视线垂直于硅質壁的 殼環。 Haptonema: A flagellum-like structure in haptophytes which arises from the cell apex near the flagella and contains several microtubules. It facilitates cell attachment, feeding and avoidance responses. 定鞭毛：定鞭藻的鞭毛狀結構，由鞭毛附近的細胞頂端伸出，內有數根微管。定鞭 毛的作用是輔助細胞黏附、攝食或作出躲避反應。 Hypocone: The portion of a dinoflagellate cell posterior to cingulum.
