<h3><u>Phloem sap: what is it?</u></h3>
Phloem sap, which is mostly dissolved in water, is made up of minerals, hormones, and carbohydrates. It moves from where carbohydrates are produced or stored (the sugar supply) to where they are consumed (sugar sinks).
The pressure flow idea suggests a mechanism for phloem sap transport notwithstanding the availability of competing theories. It is believed that phloem sap from vascular plants facilitates the transmission of informational impulses.
Phloem sap is consumed as the only or main source of food by a relatively small range of animals. It is "nutrient-rich relative to many other plant products and typically low in toxins and feeding deterrents."
