What identifies this cell as a bacterial cell rather than a plant cell?
A bacterial cell has no nucleus. It is prokaryotic, meaning before nucleus, whereas a plant cell has a nucleus and is eukaryotic, meaning true nucleus. Also, plant cells are often specialized whereas bacterial never are.
Cells with a defined nucleus?
A cell.
What cell part contains an organism's genome?
The nucleus of the cell contains the genome.
When does replication occur?
Biological replication is of two types 1: DNA replicationwhich occurs in nucleus during S stage of Interphase of cell cycle before cell division and 2 : cell division is considered cell replication .
What is the organelle that directs a cell's activities?
The cytoskeleton is what controls movement in a cell.
What kind of cell that does not have a nucleus?
A prokaryote is a cell without a nucleus. The prefix Pro- means before, in this case, before the nucleus developed. A cell with a nucleus is a eukaryote.

What is a prokayote cell?
a prokaryotic cell is a cell that has no nulcleus (as pro means before and karyon mean nucleus), it has no membrane bound organelles and is simple in structure and has 70s ribosomal units
