Question

cytoplasm containing cell parts
cell membrane

Explanation:

The diagram appears to be of a prokaryotic cell (like a bacterium). The left label "cytoplasm containing cell parts" should correspond to the cytoplasm (the area with the dotted structures and the genetic material). The right label "cell membrane" should correspond to the inner membrane layer (the yellowish layer inside the cell wall, if present, or the membrane enclosing the cell). So the left blank (under "cytoplasm containing cell parts") would be the cytoplasm (with ribosomes and nucleoid), and the right blank (under "cell membrane") would be the cell membrane structure.

Answer:

Left blank: cytoplasm (with ribosomes, nucleoid, etc.)
Right blank: cell membrane (the inner lipid - bilayer membrane)
