In the image, we can see a round segmented worm (A) and a flat unsegmented worm (B).
Worm A seems to belong to the phylum Annelid, which members are characterized by having its body divided into multiple segments, while worm B seems to be part of the Platyhelminthes phylum, with flat and unsegmented bodies given that they don't have a circulatory system.

Answer:
a It has membrane-bound organelles
b It converts stored energy to use for cellular processes
Explanation:
Prokaryotic cells lack membrane-bound organelles such as a nucleus and mitochondria, that are present in eukaryotic cells. However, they do have a cell membrane that separates the cell from the outer environment.
Prokaryotic cells do not have mitochondria to break down stored material into energy, instead they obtain their energy from light or chemical sources. This is in contrast to eukaryotic cells, which can break down sugars to produce energy.
Single celled prokaryotes and eukaryotes can both possess flagella
