Plant cells have plastids and larger vacoule and they also have tough cellulosic cell wall outer to cell membrane as a covering.
Animal cells don't have cell wall rather they have cell membrane as it's outermost covering and they have smaller vacuoles.They also don't have plastids.They have centrosome which is not found in plant cells.
The cell’s DNA is replicated or copied before cell division because it is important for the cell to have 2 DNA molecules because the cell is going to divide into 2. Each new cell need a 1 DNA
