The result show the ommatida that form the compound eye in penaeus monodon fabriciu were composed of cornea , four cone cells , eight retinular cells and some pigment cells 结果发现:组成复眼的小眼表形为长方形,从远端到近端分别由角膜、二个角膜生成细胞、四个晶锥及八个小网膜细胞构成。
When the pigment absorbs light ( or , more precisely , absorbs discrete packets of energy called photons ) , the added energy causes the retinal to change shape , triggering a cascade of molecular events leading to excitation of the cone cell 视色素一旦吸收了光线(更精确的说法是吸收了称为光子的特定能量单元) ,新增加的能量就会改变视黄醛的形状,因而引发一连串的分子事件,造成锥细胞的兴奋。
An ommatidium is composed of cornea , two corneagenous cells , four cone cells , eight retinular cells , rhabdom , distal pigment cells , distal and proximal reflecting pigment cells , in blue , red and in full bright light conditions , compound eyes exhibit obvious characters the disarrangement of microvilli in the rhabdom , the increased number of lamellar bodies , distal and proximal pigment granules covering the crystalline cone and rhabdom to prevent hard light damaging the ommatidia 现将我们的研究结果报道如下:日本沼虾复眼属于反射型重叠像眼,每一小眼由角膜,成角膜细胞( 2个) ,晶锥细胞( 4个) ,小网膜细胞( 8个)及其形成的感杆束和远端色素细胞、远端反光色素细胞、近端反光色素细胞组成。小眼角膜长方形,小眼密度为512个mm ~ 2 。
