Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically
