Why is it important for dna to be duplicated before mitosis

Answers

If it didn't, one cell would end up with the original DNA, the other wouldn't be a functional cell, because it would lack DNA. If the DNA was split between the two cells, neither cell would have a complete copy.

What would happen if the membrane did not allow water or solute particals to pass through it

Answers

If the cell membrane does not allow the water or solute particles to pass through it then the cell will be deficient in those particles which could even lead to the deathof cell.

What is Cell membrane?

The animal cell has an outermost covering which is known as the cell membrane or the plasma membrane. It is selectively permeable in nature. It only allows some solute particles to move across it. The cell membrane does not allow all the particles to move across it, as a result the restricted particles requires a protein or ligand through which it can cross the membrane.

Cell membrane is made up of phospholipids and membrane proteins. Their is a lipid-bilayer in which some proteins are embedded are known as integrated proteins and some are present on the membrane. Cell membrane is present in all types of cells, however a cell wall is also present in plants outside the cell membrane.
