1. Diagram of a longitudinal section of a cryptophyte

2. Sieve elements of Nereocystis

3. Diagram of a brown algal cell

4. Pyrenoids of a brown algal cell

5. Chloroplast of Fucus

8. they are located with in the chloroplast but not close to the flagella

9. the eyespot operates by either intercepting light (shading) or reflecting light (increasing the illumination) onto the photoreceptor pigment

13. Euglena longitudinal section - Note the distinctive outer covering, the pellicle

14. Outer view of a haptophyte - The cell surface is completely encased in coccoliths , special organic scales encrusted with calcium carbonate

15. Electron micrograph of Chrysochromulina - This photograph shows the two flagella and a haptonema, the latter lightly coiled at the tip

16. Several cross-sections through a haptonema - Note the outer sheath of three concentric membranes and the inner circle of 6 or 7 microtubules

18. chloroplast envelope has 2 membranes

19. Middle photo: dinobryon (chrysophyte)

20. has a girdle lamella

21. PER surrounds chloroplast

22. chrloroplast envelope has 2 membranes

23. lower photo: trachelomonas (euglenophyte)

24. chloroplast envelope has 3 membranes

27. The 2 membranes of the chloroplast envelope and the scattered light areas containing fibrils of DNA

29. note the arrangements of the thylakoids into grana stacks (dark areas) which are connected by stroma lamellae

30. the scattered areas containing chloroplast DNA (in between the grana stacks) (NA)

33. they are located within the chloroplast but not close to the flagella

34. the eyespot operates by intercepting (shading) and/or reflecting (increasing the illumination) light onto the photoreceptor pigment, which is localized in either the plasma or chloroplast membranes over the eyespot
