Exempel på hur man kan använda FRUSTULE i en mening

• Syneresis has also been proposed as the mechanism of formation for the amorphous silica composing the frustule of diatoms.
• The frustule itself may be with or without a cell girdle, which dictate alternate germination processes, whereby the thecae of resting spores with girdles become the hypotheca and both valves are shed when the girdle is absent.
• After maximal size has been reached, a new diatom with a rigid frustule, a so-called initial cell that is significally larger than its parent cells, is formed inside the auxospore which it eventually breaks free from.
• The margins of the two thecae are covered by a connecting band called a cingulum and all together are referred to as a frustule, and the whole cell is covered by a mucilaginous layer.
• The frustule also contains many pores called areolae and slits that provide the diatom access to the external environment for processes such as waste removal and mucilage secretion.
• It is encased in a heavily silicified cell wall, called the frustule, and is identified by its unique theca, raphe and striations, which distinguish it from other diatoms.
