Roots are the underground part of the plant, and the main function is the absorption of water and minerals from the soil, conduction, storage of reserve foods and mainly in the anchorage of the plant. The chief distinction from the stems is the lacking of buds and leaf scars, but have root cap and branches that originate from internal tissues than from buds. And Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. The primary function of the stem supports the leaves and to transport minerals and water to the leaves, where it proceeded to convert into useful products by the process of photosynthesis, and then further these are transported to other parts of the plants including roots.

Explanation:

After two months of following a lower sodium diet, exercising, and losing weight, Dan's blood pressure is now categorized as prehypertension pressure or high normal blood pressure since it is between 120 to 139 mmHg for the systolic pressure and 80 to 89 mmHg for the diastolic pressure. People in this category tend to have high blood pressure in the future due to an unhealthy lifestyle, as the one that Dan had, or due to malfunctioning of the kidneys or other illnesses.

In the past, Dan was a person with hypertension because his pressure was higher than 139 for the systolic and 89 for the diastolic, this was caused due to his bad lifestyle where he ate food with high quantities of sodium, had overweight and did not exercise.
