Sushan Gaire presented on cells and their structures. The presentation covered the cell theory, types of cells (prokaryotic and eukaryotic), and organelles found within plant and animal cells. Key organelles discussed included the nucleus, which contains DNA; mitochondria and chloroplasts, which generate energy; and the cell membrane and cell wall, which surround the cell. The presentation provided definitions and examples to explain the basic unit and functions of cells.

3. Cell Theory
All living things are made up of cells.
Cells are the smallest working units of all living
things.
All cells come from preexisting cells through cell
division.

Do not have
structures surrounded
by membranes
Few internal
structures
One-celled organisms,
Bacteria

Cell Membrane
Cell Wall

13. Cell Membrane
08/28/18
13
Outer membrane of cell
that controls movement
in and out of the cell
Double layer

14. Cell Wall
08/28/18
14
Most commonly found
in plant cells &
bacteria
Supports & protects
cells

15. Inside the Cell

16. Nucleus
Directs cell activities
Separated from
cytoplasm by nuclear
membrane
Contains genetic material
- DNA

17. Nuclear Membrane
08/28/18
17
Surrounds nucleus
Made of two layers
Openings allow
material to enter and
leave nucleus

18. Chromosomes
In nucleus
Made of DNA
Contain instructions for traits & characteristics

19. Nucleolus
08/28/18
19
Inside nucleus
Contains RNA to build
proteins

20. Cytoplasm
Gel-like mixture
Surrounded by cell
membrane
Contains hereditary
material

21. Endoplasmic Reticulum
08/28/18
21
Moves materials around
in cell
Smooth type: lacks
ribosomes
Rough type (pictured):
ribosomes embedded in
surface

22. Ribosomes
08/28/18
22
Each cell contains
thousands
Make proteins
Found on ribosomes
& floating throughout
the cell

23. Mitochondria
08/28/18
23
Produces energy through
chemical reactions –
breaking down fats &
carbohydrates
Controls level of water and
other materials in cell
Recycles and decomposes
proteins, fats, and
carbohydrates

24. Golgi Bodies
08/28/18
24
Protein 'packaging
plant'
Move materials
within the cell
Move materials out of
the cell

25. Lysosome
08/28/18
25
Digestive 'plant' for
proteins, fats, and
carbohydrates
Transports undigested
material to cell
membrane for removal
Cell breaks down if
lysosome explodes

26. Vacuoles
08/28/18
26
Membrane-bound
sacs for storage,
digestion, and waste
removal
Contains water
solution
Help plants maintain
shape

27. Chloroplast
08/28/18
27
Usually found in plant
cells
Contains green
chlorophyll
Where photosynthesis
takes place
