Xylem and Phloem. They are both part of the vascular tissue. Xylem is responsible for the movement of water and minerals from the roots to the leaves for photosynthesis. Phloem transports the sugar made during photosynthesis from the leaves to different parts of the plant. I'm pretty sure that water is included when the sugar is transported (in phloem) but you should just check if water is transported after photosynthesis just to make sure
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
