Summary Introduction
Introduction: Vascular system is a system in plants where the conducting tubes, such as xylem and phloem are present. The xylem vessel helps in transporting the water and the minerals from the roots to the leaves, and the phloem vessels are involved in transporting the prepared food (glucose) from leaves to all parts of the plants.

Students have asked these similar questions
The vascular system in piants is made up of two tissues: phloem and xylem.
(a) Mark on the image above the positions of the xylem and phloem.
(b) Differentiate between these vascular tissues.
(c) Identify and describe a recent technology used to determine plant structure.
The apoplast is (a) a layer of cells that surround the vascular region in roots (b) the layer of cells just inside the endodermis (c) a system of interconnected plant cell walls through which water moves (d) the central cylinder of the root that comprises the vascular tissues (e) a continuum of cytoplasm of many cells, all connected by plasmodesmata
6) Match the tissue on the left with the description of the function it generally performs for the
plant on the right:
a) phloem
flexible support, such as in petioles and herbaceous stems.
b) xylem
forms an outer barrier for leaves, young stems and roots.
c) collenchyma
conducts water and dissolved nutrients from the roots to
other plant tissues.
support of vascular tissue in older woody plants and
formation of very hard plant structures such as nut shells.
d) periderm
e) parenchyma
metabolism and storage.
f) sclerenchyma
conducts molecules produced by the plant throughout the
plant body.
g) epidermis
provides physical protection for woody plants.
