3. INTRODUCTION
Our earth is a beautiful place where in different types of organisms happily coexisted.
From minute mosses to huge conifers invisible bacteria to huge blue whale, all have a basic unit ca

6. CELL
The cell is the basic structural and functional unit of life.
Cell is the building unit of living organisms.
Our body is made up of many different kinds of cells.
Each type of cell is specialized to perform a specific function..
Depending on the function cell has specific shape ,size and
may have some components which other type of cells do not
have.

 The boundary of the animal
cell is the plasma membrane
which is also called as cell
membrane.

9. C E L L WA L L
The cell wall is formed from
various compounds the main
being cellulose
Cellulose helps to maintain the
shape of the plant cell.
This allows the palnt to remain
rigid and upright even if it
grows to great heights.
Each cell is interconnected with
its neighbouring cells through
openings called
plasmodesmata.

10. C Y TO P L A S M
The cytoplasm includes all living
parts of the cell within the cell
membrane excluding nucleus.
The cytoplasm is made up of
cytosol and cell organelles.

11. P R OTO P L A S M
In particular , the material inside
and outside the nuclear
membrane is known as
protoplasm.

12. M I TO C H O N D R I A
Mitochondria is an oval or rod
shaped double membrane
bound organelle.
Aerobic respiratory reactions
takes place within the
mitochondria to release energy.
It is known as the power of the
cell.

13. C H LO R O P L A S T
Chloroplast produce food from
the sun’s energy.
Only plants with chloroplast are
able to do the photosynthesis
because they contain the very
important green pigment called
chlorophyll.
Animal cell lacks chlorophyll.

14. G O LG I C O M P L E X
Membrane bounded sacs are
stacked on top of the other with
associated secretory vesicles are
collectively knowna s golgi
complex.
It helps in the production of
secretory substances ,
packaging and secretion.

15. LYS O S O M E
Lysosome is the main digestive
compartments of the cell.
It lyse a cell and hence it is
called suicidal bag of the cell.
Centrioles are present only in
animal cell and absent in plant
cells.
It helps in the separation of the
chromosomes during cell
division.

16. C E N T R I O L E S
Centrioles generally found close
to the nucleus and are made up
of tube like structures.

17. E N D O P L A S M I C
R E T I C U LU M
ER is an inter membranous
network made up of flat or
tubular sacs within the
cytoplasm.
RER has ribosomes which helps
in protein synthesis.
SER helps in the synthesis of
lipids.

18. N U C L E U S
Plant and animal cells have
nucleus inside the cytoplasm.
It controls all the process and
chemical reactions that takes
place inside the cell.
It helps to transfer the inherited
character from one generation
to the next generation.

19. CONCLUSION
As far as cell is considered it is the basic and functional unit of life which helps in the
body’s metabolism.
If a cell is no longer needed then it is subjected to programmed cell death or also
known as a apoptosis.
Cell death usually occurs if the the cell is lysed by any chemical or molecular damage.
Though life starts from cell it needs to undergo various differentiation to perform
specific function .
