 Learning about Vascular tissue development

4. Definition of vascular tissue
It is a complex conducting tissue, formed of more than
one cell type, found in vascular plants. The
primary components of vascular tissue are the xylem and phloem.

5. Meaning of fruit
There are two types of vascular tissue: xylem and phloem.

6. Types of vascular tissue-xylem
 Xylem
Tracheids
Vessel members
Parenchyma
● Primary Xylem
Protoxylem
Metaxylem
● Secondary Xylem

7. Types of vascular tissue
The xylem is principally a water transport tissue. It moves water and
material dissolved in water from the roots to the leaves. The xylem is
composed of two tracheary elements.
Tracheary elements must die first before they assume their
ultimate function of transporting water and dissolvedmaterials.
The xylem is composed of two tracheary
elements: vessel elements and tracheids.

8. Types of vascular tissue-phloem
 Phloem
Sieve Cells
Sieve tube members
Companion cells
Phloem parenchyma
● Primary Phloem
Protophloem
Metapholoem
● Secondary Phloem

9. Phloem tissue
The phloem consists primarily of living cells. A characteristic cell of the
phloem is the sieve tube member.
Sieve tube members often transport food.
Sieve plates appear when enzymes break up the ends of the tubes and
connect the contents of neighbouring cells.
The phloem often has companion cells with it. These cells aid in
transport.

10. Vascular tissue
development

11. Development of vascular tissue is a remarkable example of
intercellular communication and coordinated development involving
hormonal signalling and tissue polarity. Thus far, studies on vascular
patterning and regeneration have been conducted mainly in trees
woody plants with a well-developed layer of vascular cambium and
secondary tissues.
