The transport system in vascular plants
There are two different transport tissues in vascular plants, called xylem and phloem.
-Xylem: transports water and dissolved minerals from the roots to the stem and leaves. This tissue is composed of dead cells that lack an end wall between adjacent cells. The side walls are thick and reinforced with lignin, which makes them rigid and waterproof.
-Phloem: transports food ( sugars dissolved in water) from the photosynthetic cells to other parts of the plants for growth or storage. This type of tissue is made up of living cells separated by terminal walls with small perforations.
Taking this information into account, the plant transport system is made up of 2 types of tubes, the ones of the xylem and the ones of the phloem.
