TISSUES
1) Tissues
:-
Tissue is a group of cells having similar structure and function.
In plants and animals groups of cells called tissues carry out
specific functions.
Eg :- In human beings the cells of the muscular tissue contract and
relax and help in movements.
In plants the cells of the vascular tissue conduct water and food
from one part of the plant to the other.

2) Differences between plant and animal 
tissues :-
a) Plant tissues :-
• Plants do not move from place
to place.
• tissues consists of dead cells
because they provide
mechanical support and
strength to the plant.
• The growth of plants takes place
only in some regions.
b) Animal tissues :-
• Animals move from place to
place and need more energy
than plants.
• Cells and tissues in animals are
living cells.
• The growth of animals is more
uniform.
• They do not have separate
dividing and non dividing cells.
• similar Cells come together to
form tissues which in turn form
organs which perform specific
functions.
• Have tissues called
meristematic tissues which
divide and help in growth.
• Have permanent tissues which
do not divide.

Plant Tissue
Plant tissues are of two main types. They are Meristematic tissues and
Permanent tissues.
i) Meristematic tissues :- are of three types. They are Apical
meristematic
tissues, Intercalliary meristematic tissues and Lateral meristematic
tissues.
ii) Permanent tissues :- are of two types . They are Simple permanent
tissues
and Complex permanent tissues. Simple permanent tissues are of
three
types. They are Parenchyma, Collenchyma and Sclerenchyma.
Complex
permanent tissues are of two types. They are Xylem and phloem
