The document discusses the key components and structures of plant cells. It notes that plant cells were discovered by MJ Schleiden and contain organelles such as a cell wall, cell membrane, nucleus, mitochondria, endoplasmic reticulum, Golgi complex, plastids, ribosomes and vacuoles that allow the cell to carry out its functions. The cell wall provides structural support, while organelles such as the mitochondria and chloroplasts help with energy production and storage.

2.  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.

3.  Cell wall
 Cell membrane
 Protoplasm
 Cytoplasm
 Mitochondria
 Endoplasmic
reticulum
 Golgi complex
 Plastids
 Nucleus
 Ribosome
 vacuoles
 Cytoskeleton

4.  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

5. CELL MEMBRANE
 Responsible for
controlled entry and exit
of molecule.

6.  All substance inside the cell membrane
constitute protoplasm
 The part of protoplasm excluding
nucleus called cytoplasm.

7. 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)

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

9. 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 .

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

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

12. 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

13.  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)

14. CONCLUSION
 Cell is the basic unit of our life.
 Plant cell was discovered by MJ Schleiden.
 Plant cell contains many cell organelles such
as Nucleus, Mitochondria, Golgi complex,
Endoplasmic reticulum, Plastids etc.
