Some retain plastids, but not chloroplasts, while others have lost plastids entirely.
Many algae and plant species contain photosynthetic membrane-bound organelles called plastids that are actually remnants of a free-living cyanobacterium.
A loss of these enzymes, for example a loss of the GWD, leads to a starch excess (sex) phenotype, citation and because starch cannot be phosphorylated, it accumulates in the plastids.

The structure and function of plastids.
This method can be used on plants that are not susceptible to Agrobacterium infection and also allows transformation of plant plastids.
While there are numerous examples of mitochondrial descendants ( mitosomes and hydrogenosomes ) that have lost their entire organellar genome, citation non-photosynthetic plastids tend to retain a small genome.
