Chloroplast of Fucus
Electron micrograph of a cryptophyte
-The large ejectosomes seen here line the wall of the gullet
-Part of a smaller ejectosome is visible just beneath the plasmalemma on the lower left side of the cell
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
Interphase nucleus and chromosomes of a
dinoflagellate
-The chromosomes lack histones, are permanently condensed and have a characteristic banded appearance
-There is a large nucleolus within the nucleus
Interphase nuclei of a green alga and a
euglenophyte
-Note the condense chromosomes of the euglenophyte
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
Euglena
