Sap: important for plant nutrient transport
What is (definition)
In botany, sap is a liquid that circulates in vascular plants. We can say that it is the equivalent of human blood.
The function of sap in vascular plants is to transport nutrients to all plant cells. These nutrients are necessary for the growth and redistribution of organic substances produced by the photosynthesis process.
Types of sap
Produced in the roots of plants. It is formed from the absorption of the solution found in the soil. Through xylem cells, it is led to the leaves and stem. Crude sap is used by the plant to produce organic substances for processing into elaborate sap.
The elaborated sap is formed mainly by glucose (produced in the photosynthesis process). Through the phloem vessels, the elaborate sap is taken to all plant tissues, enabling the cells to feed.
Use of sap
The sap of various vegetables has been used for centuries by humans for various functions. Rubber sap, for example, is used in the manufacture of rubber.
Many animals, especially insects, feed on the sap of some plant species.
