3.  Robert Hooke (1665) is credited with the
discovery of cell.
 The cell is the Basic unit of life.
 All the activities of an organism are present in
miniature form in each and every cell.
 Cell retain the dual existence as a distinct entity
(unicellular organism) and a building block in
the construction of multicellular organism.
 There are two types of cell- prokaryotic and
eukaryotic cell.

4.  Nucleus
 Protoplasm
 Plasma membrane
 Golgi complex
 Mitochondria
 Chloroplast
 Ribosomes
 Endoplasmic
reticulum
 Vacuoles
 Flagella, cilia etc.

5.  Cilia and flagella are locomotive
organ of cell
 They are hair like structure
 Their origin is from cytoplasm
 Cilia may be 5 to 10 µ in length and
 Flagella is up to 150 µ long

7.  Lower part is basal
body or kinetosomes
 The part above is the
shaft
 Between them basal
plate is present
 Basal body consist 9
peripheral triplets
 Each triplets is
composed of 3 sub
fibrils A B C.

8.  Shaft of cilia length
from5 to 10 µm. And
flagellum may be 150
µm.
 The arrangement of
microtubules is in 9 fold
and it is called
exoneme.
 The diameter of
exoneme is 0.21 µm.
 In shaft exoneme
consists of 11
longitudinal fibrils.
STRUCTURE

9.  They are in 9+2
arrangement.
 9 peripheral and 2
central fibrils.
 Ciliary rootlets
attached to the
proximal end of the
basal body.
 They act as anchor of
the basal body.

10.  Locomotion
 Feeding
 Cleansing
 Respiration
 Circulation
 Passage of materials

11.  Pendulous movement :
 Unciform movement
 Infundibuliform movement
 Undulant movement

12.  Pendulous
movement :
 Unciform
movement
 Infundibuliform
movement
 Undulant
movement
The cilium moves in one
plane. It is flexed at its
base and remains rigid
during motion. This
type of movement is
found in the ciliated
Protozoa, e.g.
Paramecium.

13.  Pendulous
movement :
 Unciform
movement:
 Infundibuliform
movement
 Undulant
movement
It also takes places in
one plane. The
cilium bends into
the shape of hook
during contraction.
Unciform movement
is common in the
Metazoa.

14.  Pendulous
movement :
 Unciform
movement:
 Infundibuliform
movement:
 Undulant
movement
The cilium or
flagellum rotates at
its base and move in
different planes,
describing a funnel-
shaped figure.

15.  Pendulous
movement :
 Unciform
movement:
 Infundibuliform
movement:
 Undulant
movement:
The waves of
contraction start from
the base and move to
the tip. Most flagella
show undulant
movement.

16. Unciform and Infundibuliform movement

17. (a) Pendulous , (b) undulant movement

18. Cilia and flagella contain
 70 to 80% protein
 13 to 23% lipid
 1 to 6% carbohydrate
 0.2 to 0.4% adenine and uracil nucleotide
 Central fibrils and arms of subfibrilsA contain
protein dynein having an enzyme ATPase
 The peripheral fibrils posses a protein which
closely resemble the protein of muscle cells, the
actin.
