plant cell organelles

3. INTRODUCTION
 Cell is the structural and functional unit of an organism.
 Cell was discovered by Robert Hooke.
 There are mainly two type of cells are present
Plant cell
Animal cell
• M J Schleiden discovered that plant body is made up of cell.
• Cell theory was formulated by M J Schleiden and
Schwan.

4. Plant cell
 Cell wall
 Cell membrane
 Protoplasm
 Cytoplasm
 Mitochondria
 Endoplasmic reticulum
 Golgi complex
 Plastids
 Nucleus
 Ribosome
 vacuoles
 Cytoskeleton

5. Cell wall
 The cell wall is a tough,
flexible and sometimes
rigid layer that
surrounds plant cell.
 It surrounds the cell
membrane and provides
these cells with
structural support and
protection.

6. Cell membrane
 Responsible for
controlled entry and
exist of molecule.

7. Protoplasm and Cytoplasm
 All substance inside the
cell membrane
constitute protoplasm
 The part of protoplasm
excluding nucleus called
cytoplasm.

8. Mitochondrion
 Power house of the cell.
 Helps in production and
storage of energy
 They use complex
molecules and oxygen to
produce a high energy
molecule know as ATP
(Adenosine
Triphosphate)

9. Nucleus
 Considered as the
regulatory centre of the
cell.
 Nuclear membrane,
nucleoplasm, chromatin
reticulum, nucleolus,
nuclear pore are the
different parts of
nucleus.

10. Endoplasmic reticulum
 It is called the
cytoskeleton of the cell,
because it provides
firmness and shape to
the cell.
 Conduction of material
inside the cell take place
through this .

11. Ribosome
 Centre of protein
synthesis in the cell.
 Seen either attached to
endoplasmic reticulum
or free in cytoplasm.

12. Vacuole
 Covered by characteristic
membrane called
tonoplast.
 Stores water , salts,
excretory materials etc

13. Golgi complex
 Groups of flattened disc-
like structures located
close to the endoplasmic
reticulum..
 The Golgi apparatus
receives proteins and
lipids (fats) from the rough
endoplasmic reticulum

14. plastids
 Cell organelles found in
plants.
 They are mainly 3 type of
plastids
 Chloroplast(green colour)
 Chromoplast( colour to
fruits and flowers)
 Leucoplast(no specific
colour)

15. Conclusion
 Cell is the basic unit of our life.
 Plant cell was discovered by M J Schleiden.
 Plant cell contains many cell organelles such as
Nucleus, Mitochondria, Golgi complex, Endoplasmic
reticulum, Plastids etc.
