The presentation focuses on cells, describing them as the basic unit of life and referencing their discovery by Robert Hooke in 1665. It outlines various cell components such as the nucleus, vacuoles, mitochondria, and chloroplasts, detailing their functions within the cell. Additionally, it includes contact information for Dr. Mojibur Rahman Khan from the College of Agricultural Sciences.

1. Welcome
To
My
Presentation

2. Tropic of my Presentation
is…….
Inside the Cell

3. What is Cell …?
The word cell comes from the Latin “cellula” which
meaning is "a small room".
The cell is the basic structural and functional unit of
all living organisms. It is the smallest unit of life .

4. History of Cell
The cell was discovered by Robert Hooke in
1665.
Robert Hooke
Born : 28th July1635
Fields : Physics and chemistry
Institutions : Oxford University
Died : 3rd March 1703 (aged 67)

5. Cell Parts and Their Functions
Nucleus
- Large Oval body near the centre of the cell.
- The control centre for all activity.
- Surrounded by a nuclear membrane.

6. Nucleoplasm
- is the protoplasm in the nucleus.
- contains genetic material (DNA)
Cell Parts and Their Functions
Deoxyribonucleic acid

7. Nucleolus
- is found in the nucleus.
- contains more genetic information (RNA)
Cell Parts and Their Functions

8. Cell Membrane
Cell Parts and Their Functions
- the outer boundary of the cell.
- it separates the cell from other cells.

9. • Cell Wall ( Plant Cells Only )
- non living structure that surrounds the plant cell.
- protects + supports the cell.
- made up of a tough fibre called cellulose.
Cell Parts and Their Functions

10. Cytoplasm
- cell material outside
the nucleus but within
the cell membrane.
- clear thick fluid.
- contains structures
called organelles.
Cell Parts and Their Functions
The cytoplasm is all the blue, gel-like liquid
surrounding the organelles

11. Vacuoles
- are clear fluid sacs that act as
storage areas for
food, minerals, and waste.
- in plant cell the vacuoles are
large and mostly filled with
water. This gives the plant
support.
- in animal cells the vacuoles are
much smaller.
Cell Parts and Their Functions

12. Mitochondria
- power house of the
cell.
- centre of respiration of
the cell.
- they release energy for
cell functions.
Cell Parts and Their Functions

13. Chloroplasts ( Plant cells only )
- contains a green pigment known as
chlorophyll which is important for
photosynthesis.
Cell Parts and Their Functions

14. Ribosomes
- tiny spherical bodies that
help make proteins.
- found in the cytoplasm or
attached to the endoplasmic
reticulum.
Cell Parts and Their Functions

15. Endoplasmic Reticulum
- systems of membranes
throughout the cytoplasm.
- it connects the nuclear
membrane to the cell
membrane.
- passageway for material
moving though the cell.
Cell Parts and Their Functions

16. Golgi Bodies
- tube like structures
that have tiny sacs at
their ends.
- they help package
protein.
Cell Parts and Their Functions

17. Lysosomes
- small structures that
contain enzymes which are
used in digestion.
- if a lysosome were to
burst it could destroy the
cell.
