This document discusses different types of plant tissues. It explains that tissues are groups of similar cells that work together to perform a specific function. There are three main types of permanent tissues: simple permanent tissues which are made up of one type of cell; collenchyma which provides flexibility and mechanical support; and sclerenchyma which makes plants hard and stiff. Complex permanent tissues are made of multiple cell types that coordinate to perform a common function, such as xylem and phloem which transport water and nutrients. Xylem tissue specifically contains tracheids, vessels, parenchyma and fibers that transport water and minerals vertically while also providing structure and storing food.

3. Cells specializing in one function are often
grouped together in the body. This means
that a particular function is carried out by a
cluster if cell at a definite place in body. This
cluster of cell, is known as Tissue, so as to
give the highest possible efficiency of
function example:- blood, muscles etc.
Or in other words Tissue is a group of cells
that are similar in structure and/or work
together to achieve a particular functions.

15. The tissues which are made up of one type of
cells, which look like each other are known are
simple permanent tissue.

20. The flexibility in plants is due to another
permanent tissue, collenchyma. It allows easy
bending in various parts of plants without
breaking it. It also provide mechanical support
to the plants. The cells of this tissue are living
elongated and irregularly thickened at the
corners. There is very little intercellular
spaces.

22. It is the tissue which makes the plant hard and
stiff. We have seen the husk of coconut. It is
made of this tissue. The cells of this tissue are
dead. They are long and narrow as the walls are
thickened due to lignin (a chemical substance
which act as cement and hardens them). There
are no internal spaces between the cells. It is
present in stems around vascular bundles, in the
veins of leaves and in hard covering of seeds. It
provides strength to plant cell.

23. Complex permanent tissue are made of more
than one type of cells. All these cell coordinate
to perform a common function. Xylem and
phloem are examples of such cells.

27. It consists of tracheids, vessels,
xylem parenchyma and xylem
fibers. The cells of this have
thick walls and many of them
are dead cells. Tracheids and
vessels are tubular structure to
transport water and minerals
vertically. The parenchyma
stores food and helps in side
ways conduction of water.
Fibers are mainly supportive in
nature.
