Answer:

The different types of tissues we have

discussed until now are all made of one type

of cells, which look like each other. Such

tissues are called simple permanent tissue.

Yet another type of permanent tissue is

complex tissue. Complex tissues are made of

more than one type of cells. All these cells

coordinate to perform a common function.

Xylem and phloem are examples of such

complex tissues. They are both conducting

tissues and constitute a vascular bundle.

Vascular or conductive tissue is a distinctive

feature of the complex plants, one that has

made possible their survival in the terrestrial

environment. In Fig. 6.3 showing a section of

stem, can you see different types of cells in

the vascular bundle?

Xylem consists of tracheids, vessels,

xylem parenchyma (Fig. 6.7 a,b,c) and xylem

fibres. The cells have thick walls, and many

of them are dead cells. Tracheids and vessels

are tubular structures. This allows them to

transport water and minerals vertically. The

parenchyma stores food and helps in the

sideways conduction of water. Fibres are

mainly supportive in function.

Phloem is made up of four types of

elements: sieve tubes, companion cells,

phloem fibres and the phloem parenchyma

[Fig. 6.7 (d)]. Sieve tubes are tubular cells with

perforated walls. Phloem is unlike xylem in

that materials can move in both directions in

it. Phloem transports food from leaves to other
