In binary fission, the bacterial chromosomes stay attached to the cell membrane.

Further Explanation:

Bacterial binary fission refers to the process which bacteria utilize to carry out the cellular division. It is similar in concept to the mitosis, which occurs in the eukaryotic organisms. However, the purpose is different. In the case of mitosis, the cell divides in the body of the organism; they cause the organism to grow or substitute the old and worn-out cells with the new ones. However, in the case of bacteria, the cell division is not just a way of producing more cells but also the way bacteria reproduce or add more bacteria to their population.

Binary fission begins by dividing the bacteria as it needs to copy the DNA. Copying of the DNA by the replication enzymes starts at the spot found on the chromosome, which is called the origin of replication. The replication continues, and 2 origins move towards the opposite terminals of the cell and pull the rest of the chromosome, which is attached to the cell membrane.

They're attached to the plasma membrane.
(it's at the midpoint of the cell.)

Tta ttc ctg i hope its right.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
