Epidermal tissue
The epidermis is a single-layered group of cells that covers plants
leaves, flowers, roots and stems.
In stems it protects against water loss,
In roots it absorbs water and mineral nutrients
Cuticle
Single layer of cell
Root hairs
Stem Epidermis
Root Epidermis
Has thin walled cells and stomata for transpiration. Leaves of xerophytic plants
have thick layer of cutin to prevent water loss .

Tissue
 The tissue is avascular, or without blood vessels.
Epithelial Tissue
 The cells within this tissue are firmly attached to each other.
 The upper surface of epithelium is free, or exposed to the
outside of the body or to an internal body cavity.
 A thin, extracellular layer called the basement membrane forms
between the epithelial and connective tissue.

Inner lining of nose ,ear, tongue ,glands
Uterus and Fallopian tubes
Outer layer of skin
Cells are thin and flat.
Cells are cuboidal in shape
Columnar
The cells are elongated
and column-shaped
Ciliated
Stratified Epithelium
composed of several
layers of cells
Functions of Epithelial Tissue
 Protection - Epithelial cells from the skin
protect underlying tissue.
 Diffusion -Simple epithelium promotes the diffusion
of gases, liquids and nutrients..
 Absorption- Certain epithelial cells lining the small
intestine absorb nutrients from the digestion of food.
 Secretion- In glands, epithelial tissue is
specialised to secrete specific chemical substances
such as enzymes, hormones and lubricating fluids.
.
 Sensation- Specialised epithelial tissue
containing sensory nerve endings is found in the
skin, eyes, ears, nose and on the tongue
Connective Tissue
These living cells are responsible for
secreting the large amounts of
intercellular ground substance
(matrix).

Connective tissue is composed of:
1.Cells
2.Extracelluar matrix.
Cells are generally widely spread.

 The most widespread connective tissue
of the body.
 It is used to attach the skin to the
underlying tissue.
 It also fills the spaces between various
organs and thus holds them in place as well
as cushions and protects them
Collagen fibers
Elastin fibers
Areolar Adipose
Adipocytes
 It is a connective tissue
composed of adipocytes.
 It is composed of roughly
80% fat;
 Its main role is to store fat and it
also cushions and insulates the
body

Types of connective tissue
Types of connective tissue
TendonTendon
 A tendon is a tough band of fibrous
connective tissue that usually connects
muscle to bone.
 Tendons are mostly composed of parallel
strands of collagen fibres closely packed
together
LigamentLigament
 A ligament is made up of
collagen fibers arranged parallely.
 A ligament joins two bones at
joints.
 The fibbers in ligaments are
arranged in criss-crossed layers.
Types of connective tissue
Cartilage
 It is found in the pinna of the
ear,windpipe, nasal septum and in the
epiglottis.
 Made up of dense matrix of collagen
fibres and elastic fibres. The cells are
called chondrocytes.
 Reduces friction at joints
Functions
 Support The cartilagenous rings in the
windpipes (trachea and bronchi) assist in
keeping those tubes open.
 Maintain shape. In the ear cartilage
helps to maintain the shape and
flexibility of the organ
Structure of bone
 The bone matrix has two main
components :
Organic matrix –Has collagen
fibbers.
Inorganic salts-Has mainly
calcium salts.
 Bone cells are osteocytes
which have long processes
called canaliculi
 The skeleton is built of bone tissue.
Bone provides the internal support of the
body
 Bone provides protection for the vital
organs of the body: the skull protects the
brain; the ribs protect the heart and lungs.
FUNCTIONS OF BONE TISSUEFUNCTIONS OF BONE TISSUE
 Provides sites of attachment of tendons
and muscles, essential for locomotion.
 The main store of calcium and
phosphate is in bone
