| Chloroplast structure. A. Chlorophytes and prasinophytes (hatched areas indicate internal starch). B. Euglenoids. C. Dinoflagellates. D. Cryptomonads (NE: nuclear envelope; CER: chloroplast endoplasmic reticulum). E. Haptophytes. F. Chrysomonads, xanthophytes, chloromonads. Eustigmatophytes have chloroplasts that resemble type E, but lack CER. F. Phaeophytes and diatoms. (GL, the girdle lamella). The rhodophytes have a chloroplast that resembles type A, but they do not have stacked thylakoids and produce their floridean starch external to the chloroplast. |
