Do plastids in Dendrobium cv. Lucky Duan petals function similar to autophagosomes and autolysosomes?

In animal cells a double-membrane-bound structure, the autophagosome, encloses a portion of the cytoplasm. The encapsulated material becomes digested after fusion of the autophagosome with a vesicle containing lytic enzymes. The autophagosome is then termed autolysosome.
