Vascular tissue in plants transports water and nutrients throughout the plant. It consists of two main components: xylem and phloem. Xylem transports water and minerals from the roots to other parts of the plant. It consists mainly of dead cells. Phloem transports organic nutrients made during photosynthesis, such as sugars, throughout the plant. Unlike xylem, phloem consists of living cells.

2. In plants different parts absorb water and send it to
all parts of the plant.
The tissue that is involved in the transportation of
materials is vascular tissue.
The main components of vascular tissue are
Xylem and Phloem.
Xylem mainly consists of dead elements where as
Phloem consists of living elements .
In some plants they carry water to great heights in
the plant body i.e. up to nearly 330ft.
It gives mechanical support to the plant.

3.  Xylem is one of the two types of transport tissue in
vascular plants.
 This word XYLEM derived from the Greek word
Xylon (ξύλοv) which means “wood”.
 The best known Xylem tissue is wood, that is found
through out the plant.
 It’s basic function is to transport water, but it also
transfers some nutrients through the plant.
 Vessels and trachieds are responsible for the
conduction of water and minerals.

4.  Pholem is the vascular tissue which carries organic
nutrients like photosynthane.
 As the Pholem is the inner most layer of the bark its
name is derived from reek word philos.
 It mostly transports soluble organic material made
during photosynthesis. This is called translocation.
 Phloem Sieve tubes are responsible for the
conduction of organic minerals to all parts of the
body.

6. PHLOEM XYLEM
Transports food and
nutrients like sugar and
amino acids.
Bidirectional (Moves up
or down the plant’s stem
from source to sink.
Present in roots, stem
and leaves.
Living tissue with little
cytoplasm but no
nucleus.
Phloem is not star
Transports water and
minerals from roots to
aerial parts of plant.
Unidirectional (Moves up
the plant’s stem)
Present in roots, stems
and leaves.
Dead tissue at maturity
so it is hallow with no cell
contents.
Xylem. is star shape

7. Unlike xylem, the phloem is composed of
still living cells that transport sap.
The sap is water based solution, but rich
in sugars.
These sugars are transported to non-
photosynthetic areas like rots, or into
storage structures.
A hypothesis was proposed by Ernst
Munch in 1930 called Pressure flow
hypothesis that explains the mechanism
of phloem translocation.

8. Its main function is to transport water
and soluble minerals from the roots
through the plant.
It is also used to replace water loss
during transpiration and photosynthesis.
Xylem sap consists mainly of inorganic
ions and water, although it consists of
many organic chemicals.
The transport is passive, not powered by
energy.
