Transportation in Plants
Plants have evolved a variety of ways to transport materials. The simplest way is for the plant to move the material to where it is needed using its muscles. This is called primary transport. For example, plants can move water and minerals from the soil to the leaves using their roots and stems.
Another way plants move materials is by using water or air to move the material. This is called secondary transport. For example, water can move food from the roots to the leaves. Air can be used to transfer pollen from the stamen to the pistil.
Xylem and Phloem
The xylem and phloem are two types of vascular tissue in plants. The xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant, while the phloem transports nutrients and other organic molecules from the leaves to the rest of the plant. The xylem and phloem are both composed of cells called tubules, which are arranged in a series of tubes called ducts. The xylem is located in the central part of the plant, while the phloem is located on the outside.
Phloem
The sap is a sticky, watery fluid that circulates in the phloem tissue of plants. It is composed of sugars, minerals, and hormones and carries nutrients from the leaves to the rest of the plant.
Phloem sap is produced in the plant’s phloem tissue and is composed of sugars, minerals, and hormones. It circulates throughout the plant and carries nutrients from the leaves to the other parts of the plant.
