Answer and Explanation:
12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.
13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.

Explanation:
Cells undergo mitosis because there must be a process in which the nucleus is divided in order for there to be a successful reproduction for cells.
This would actually be known to originate in the "nucleic acid". This would have nothing to do with the DNA it's self, and also protein has nothing to do with it also.<span>Nucleic Acid would be small particals in the cells that would consists of molecules would some sort of chain which would then lead to the DNA, but it would actually have not resemblance of the nucleic acid at any point.
