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
