Cells that contain membrane-bound organelles are known as _____________________
cells. These cells contain a ____________________, which holds the genetic information.
The DNA in eukaryotic cells are found within _____________________________ in the
nucleus.
__________________________ cells are cells that do not contain a nucleus or other type
of membrane-bound organelle. These cells contain ______________________, but this
genetic material is not found in a nucleus. Prokaryotic cells are much
________________________ than eukaryotic cells. Bacteria are an example of prokaryotic
cells. Bacteria come in three main shapes: ______________________, spherical, or spiral.
Prokaryotes are always _________________-celled organisms, while eukaryotes can be
unicellular or multicellular.
