This document discusses different types of plant and animal tissues. It begins by defining tissue as a group of similar cells that work together to perform a common function.
The document then separates tissues into plant and animal categories. It describes the main plant tissue types as meristematic and permanent. Meristematic tissue is responsible for plant growth, and occurs in three forms: apical, lateral, and intercalary. Permanent tissues include simple tissues like parenchyma, collenchyma, and sclerenchyma, as well as complex tissues xylem and phloem.
For animal tissues, the document lists the main types as epithelial, muscular, connective, and nervous. Epithelial
slide1- introduction
slide2-Plant Tissue
Plant tissues are of two types :-
Meristematic tissue
Permanent tissue
slide3-Meristematic Tissue
Meristematic tissues continuously form a number of new cells and helps in growth and are generally made up live cells . Meristematic tissues are the group of cells that have the ability to divide. These tissues in a plant consist of small, densely packed cells that can keep dividing to form new cells. Meristems give rise to permanent tissues and have the following characteristics:
the cells are small,
the cells walls are thin,
cells have large nuclei,
vacuoles are absent or very small
there are no intercellular spaces.
Types of Meristematic Tissue
Apical Meristem:- Apical meristem is present on root apex, stem apex, leaf buds and flower buds. They are responsible for growth in length, i.e. primary growth.
Lateral Meristem: Lateral meristem is present along the side of the stem. They are responsible for growth in girth, i.e. secondary growth.
Intercalary Meristem: Intercalary meristem is present at the base of leaf or internodes. They are present on either side of the node.
slide4-Permanent Tissue [Plant Tissue]
Once the cells of meristematic tissue divide to a certain extent, they become specialized for a particular function. This process is called differentiation. Once differentiation is accomplished, the cells lose their capability to divide and the tissue becomes permanent tissue. Permanent tissues are of two types, simple permanent tissue and complex permanent tissue.
Permanent tissue gives support and are generally made up of dead cells . The cells of permanent tissues do not have the ability to divide. These cells are already differentiated in different tissue types and is now specialized to perform specific functions. They are subdivided into two groups, simple tissues consisting of cells which are more or less similar, e.g. epidermis, parenchyma, chlorenchyma, collenchyma, sclerenchyma and complex tissues consisting of different kinds of cells, e.g. xylem and phloem.
slide5-Parenchyma tissue
The cells of parenchyma have thin cell wall. They are loosely packed; with lot of intercellular spaces between them. Parenchyma makes the largest portion of a plant body. Parenchyma mainly works are packing material in plant parts. The main function of parenchyma is to provide support and to store food.
It is loosely packed and inter cellular spaces are there .
In aquatic plants , air is filled in parenchyma tissue , so they are called Arenchyma .
Parenchyma in which chlorophyll is present is called chlorenchyma .
slide6- Collenchyma tissue
In collenchyma tissue , the cells are generally elongated and are circular , oval or polygonal in cross- section. Cell wall is evenly thickened with cellulose at the corners . It is present on internodes of the plant . It is closely packed and intercellular spaces are generally absent. It is a living cell and vacuo

Living organisms are made of cells.
In unicellular organisms, a single cell performs all basic functions.
In Amoeba, a single cell carries out movement, intake of food, gaseous exchange and excretion.
Amoeba is example of unicellular cells.
Multi- cellular organisms there are millions of cells.
Each specialised function is taken up by a different group of cells.
Cells that carry out only a particular function, they do it very efficiently.
In human beings, muscle cells contract and relax to cause movement.
In human beings, nerve cells carry messages
In human beings, blood flows to transport oxygen, food, hormones and waste material and so on.
In plants, vascular tissues conduct food and water from one part of the plant to other parts.
Multi-cellular organisms show division of labour.
Definition: Cells specialising in one function are grouped together in the body to carry a particular function by a cluster of cells at a definite place in the body. This cluster of cells, is called a tissues.
These tissues are arranged and designed so as to give the highest possible efficiency of function.
A group of cells that are similar in structure and/or work together to achieve a particular function forms a tissue.
Difference
Plant Tissue: Plants are stationary or fixed, they don’t move. They have to be upright, they have a large quantity of supportive tissue. The supportive tissue generally has dead cells. The growth in plants is limited to certain regions. Some tissues in plants divide throughout their life. The structural organisation of organs and organ systems is far more specialised and localised in complex animals. Organ system design is for sedentary existence in plants
Animal Tissue: Animals move around in search of food, mates and shelter. They consume more energy as compared to plants. Most of the tissues they contain are living. The growth in animals is not limited to certain regions. Cell growth in animals is more uniform. So there is no such demarcation of dividing and non- dividing regions in animals.
The structural organisation of organs and organ systems is not far more specialised and localised than in very complex plants. Organ system design for active locomotion in animals.

The cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions. This act leading to maturation is termed as differentiation. During differentiation, cells undergo few to major structural changes both in their cell walls and protoplasm. The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. For example, formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells. While doing so, such meristems / tissues are able to divide and produce cells that once again lose the capacity to divide but mature to perform specific functions, i.e., get redifferentiated.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. DEFINITION
A group or collection of similar cells
performing or help to perform same
function and arise from the same
origin are called tissues.
The tissues are of different types
depending on the functions of the
organism, they are mainly of two
categories PLANT TISSUES and
ANIMAL TISSUES.
4. PLANT TISSUES
Plants perform functions
which are different from
animals and also their structure
is different , hence they have
tissues which are different from
animals. They are further
classified into many sub
categories which is shown in
the table below:
5. Plant Tissues
Meristimatic Tissues
(These cells continuously divide throughout the life of the
plant)
Apical
Meristem
Lateral Meristem
Intercalary
Meristem
Permanent Tissues
(Cells with speciallised structure and function that have lost
their ability to divide further)
Simple Permanent Tissue
Parenchyma
Collenchyma
Sclerenchyma
Complex Permanent Tissue
Xylem
Phloem
6. MERISTEMATIC TISSUE
The main characteristic of this
tissue is that it is responsible for the
growth of plants.
The cells of this tissue continuously
divide and later differentiate ( i.e.
get converted ) into permanent
tissue.
7. CHARACTERISTICS OF THE TISSUE
The cells are made of thin & elastic
cell wall made of cellulose.
The cells may be round , oval,
polygonal or rectangular in shape.
They are compact, having no
intercellular space.
There is a large nucleus and abundant
cytoplasm.
The protoplasm contains very few or no
vacuoles at all.
8. THIS TISSUE OCCURS AT SPECIFIC
REGIONS OF THE PLANT BODY
This is so because in plant
body growth occurs only at
these regions.
Hence , on the basis of this
there are 3 types of
meristem :
1. APICAL MERISTEM
2. INTERCALARY
MERISTEM
3. LATERAL MERISTEM
9. APICAL MERISTEM
As the name
suggests this tissue is
present at the apex
of the main & lateral
shoots and roots.
This tissue gives the
plant body a linear
growth.
10. LATERAL MERISTEM
This tissue lies on
the sides of the
plant body.
It lies under the
bark of the plant in
form of cork
cambium.
It gives the plant
it’s width or girth.
11. INTERCALARY MERISTEM
This tissue is present
at the base of the
nodes, internodes,
leaves etc.
They are also present
in between the
permanent tissue.
They give the plant
growth in length.
12. PERMANENT TTISSUE
These tissues arise from the meristematic
tissue.
The cells of this tissue gradually loose their
power to divide and acquire a definite
shape, size and function.
These tissues may be living or dead.
There are 2 types of permanent tissues
1. Simple permanent tissue
2. Complex permanent tissue.
13. SIMPLE PERMANENT TISSUE
This tissue comprises of same
type of cells which perform the
same function and all arise from
the same origin. There are three
categories of simple permanent
tissues: Parenchyma,
Collenchyma, & Sclerenchyma.
15. PARENCHYMA
Characteristics:
a) The cells are living.
b) The cells are thin walled.
c) There may or may not be
intercellular spaces.
d) They are the most
unspecialized cells.
e) No depositions are seen, the
cell wall consists only of
cellulose.
f) There is a prominent
nucleus, cytoplasm &
vacuoles.
16. There are some special types of
parenchyma tissues :
Storage parenchyma : The cells enlarge to store
nutrients & water.
Aerenchyma : Air cavities are present in the
parenchyma tissue to provide buoyancy to the
aquatic plants.
Chlorenchyma : These parenchyma cells have
presence of chlorophyll & hence can perform the
function of photosynthesis.
Parenchyma tissue is found generally in all parts of
the plant body. It forms the Ground tissue in leaves,
stem, roots & fruits etc.
17. FUNCTIONS OF PARENCHYMA
a) To store materials such as starch, proteins,
hormones etc. And waste products such as gum,
tannin, resin etc.
b) Parenchyma cells perform the metabolic activities
of the plant.
c) Forms the packaging tissue between the
specialized tissue.
d) By providing turgidity , they provide mechanical
strength.
e) Chlorenchyma helps in performing photosynthesis.
19. Characteristics:
a) It has cells which are
somewhat elongated.
b) The cell walls are thin
except at the angular region
( where the cells join). The
thickenings are caused due
to deposition of cellulose or
pectin.
c) There is o or less
intercellular space.
d) The cells are living, have
distinct nucleus & dense
protoplasm.
e) They often contain
chlorophyll.
Functions :
a) Providing mechanical
strength is the primary
function.
b) Provide flexibility.
c) Photosynthesis, as they
contain chlorophyll.
They are present below
the epidermis in dicot
stems and leaves.
They absent in dicot
roots and all parts of
monocot plants.
CHARACTERISTICS AND
FUNCTIONS
22. EPITHELIAL TISSUES
This tissue forms outer living of the
body. It protects interval organ from
external environment.
It is of four types:
Squamous.
Cubic.
Ciliated columnar.
Glandular.
23. SQUAMOUS EPITHELIUM
It is made up of
thin, flat irregular
Shaped cells .
It also forms a
selectively
permeable surface through which
filtration occurs .
24. CUBIC EPITHELIUM
It consists of cube like
cell which are square
in section but the free
surface appear hexagonal.
It is found in kindly tubules, thyroid,
vesicles and in glands.
25. CILIATED COLUMNAR
This epithelial is
formed by in the
sperm ducts.
The rhythmic,
concentrated beating of the cilia
moves solid particles in one
direction through the ducts.
26. MUSCULAR TISSUES
This tissue is that which is
responsible in our body.
This tissue is divided in three
types:
Striated muscle.
Smooth muscle.
Cardiac muscle.
27. STRIATED MUSCLE
The cells of this muscle have
many nucleus.
These muscle show alternate
light &dark bands.
These help in body movement.
These are present in our limbs.
28. SMOOTH MUSCLE
These have long cells which
have single nucleus.
The cells of this muscle is spindle
in shape.
They are also called unstraited
because we can not control them
29. CARDIAC MUSCLE
It is the muscle which is
present in heart.
These muscle are also called
involuntary muscle.
These muscle have cylindrical
&branched muscle.
30. CONNECTIVE TISSUES
It serves as storage Sid of
calcium & phosphate.
Bone provides shape &
skeleton support to the body.
Cartilage provides support &
flexibility.
31. NERVOUS TISSUE
A Tissue which is specialized to
transmit messages in our body is
nervous transmit. Brain, spinal
cord and nerves are all composed
of nervous tissues. Nervous
tissues contains highly
specialized unit cells called nerve
cells or neurons.
