A Cryptophyte eyespot
-These eyespots may be one or several layers thick
-they are located with in the chloroplast but not close to the flagella
-the eyespot operates by either intercepting light (shading) or reflecting light (increasing the illumination) onto the photoreceptor pigment
-which is probably localized in either the plasma membrane or chloroplast membranes over the eyespot
![Page 46: 320 Lab Final](https://reader034.vdocuments.us/reader034/viewer/2022042522/55a022391a28ab61108b4601/html5/thumbnails/46.jpg)
Interphase nucleus and chromosomes of a

Eyespot of a euglenophyte
-The eyespot is composed of loosely packed globules lying outside the chloroplast, next to the reservoir, opposite of the flagellar swelling
-the swelling is usually on the longer, emergent flagellum and is thought to be the site of the photoreceptor pigment
