<span>Sugars are actively loaded into companion cells from photosynthetic cells. This uses a proton/sucrose code transport proteins. This causes the Phloem to become hypertonic leading to the entry of water via osmosis. This increases turgor pressure, propelling the sugars through the plant. Then the sugar enters into the sink cells causing the phloem cells to become hypotonic, causing water to exit.</span>
Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
