5. Plasma Membrane
The plasma membrane is called
The Fluid Mosaic Model.
Composed of a double layer of
lipid molecules and proteins.
The lipid bi-layer has a hydrophilic
head and an hydrophobic head.

7. Plasma Membrane
3/3

8. Functions of the Plasma
Membrane
Regulate passage of substances
in and out of the cell.
Flexible boundary that give shape
to cell and protection of extra
cellular content.
1/2

9. Functions of the Plasma
Membrane
Communicates with other body
cells, foreign cells.
Maintain a chemical and electrical
gradient between the inside and
the outside of the cell.
2/2

10. Integral Proteins
Proteins that extend across the
lipid bi-layer that move
substances from one side of the
membrane to the other.
Integral Proteins

11. Peripheral Proteins
Proteins that attach to the inner or
outer surfaces of the membrane
to support the membrane.
Peripheral Protein

12. Cholesterol
It strengthens the plasma
membrane but decreases its
flexibility.
Cholesterol

13. Passive Movement
Substances move across the
membrane without the use of
ATP.
They move from high
concentration to low
concentration to reach
equilibrium.

14. Active Movement
Substances move across the
membrane with the use of ATP.
It moves substances against their
concentration gradient.

15. Vesicular Transport
Vesicles that transport large
particles into the cell by
endocytosis or outside of the cell
by exocytosis.
Incoming vesicle

16. Cytoplasm
Cellular material located between
the nucleus and the plasma
membrane.
Site for most cellular activities.
Where the organelles are located.

17. Cytosol
 Watery substance in the cytoplasm
that contains proteins, salts, sugars
and other solutes.

18. Organelles
Metabolic machinery of the cell.
Each organelle carries out an
specific function to maintain life of
the cell.

19. Mitochondria
Power plant of the cell, provides
the ATP to cell.
It has two membranes. The
outside membrane is smooth and
the inner membrane folds inward,
called cristae.

21. Ribosome’s
Organelle where proteins are
produced.
Free ribosome's float in the
cytoplasm and produce proteins
for use inside of the cell.
1/3

22. Ribosome’s
Attached ribosome's attach to the
endoplasmic reticulum & are
involved in the production of
proteins to be exported from the
cell.
2/3

23. Ribosomes
Attached Ribosome’s
Free Ribosome’s
3/3

24. Rough Endoplasmic Reticulum
with Ribosome’s.
Attached
Manufacture all the proteins
secreted from the cell.
Synthesize and package all the
molecules that will be secreted
from the cell.
1/3

25. Rough Endoplasmic Reticulum
Createsall the integral proteins
and phospholipids that form the
plasma membrane.
2/3

26. Rough Endoplasmic Reticulum
3/3

27. Smooth Endoplasmic Reticulum
They catalyze reactions involved
with: synthesis of steroids;
detoxification of drugs, alcohol,
pesticides, and carcinogens;
absorption, synthesis, and
transport of fats.
1/3

28. Smooth Endoplasmic Reticulum
Continuation of the Rough
Endoplasmic Reticulum.
Has no attached ribosome’s.
2/3

29. Smooth Endoplasmic Reticulum
3/3

30. Golgi Apparatus
Processes, sorts, packages, and
delivers proteins and lipids to the
plasma membrane.
Form lysosomes and secretory
vesicles.
1/2

31. Rough Endoplasmic Reticulum
2/2

32. Lysosomes
 Cells demolition crew.
 Sacs formed in the Golgi apparatus that
contain enzymes.
 Disarms ingested bacteria, viruses, and
toxins.
1/3

33. Lysosomes
 Degrades worn-out or non functioning
organelles.
 Break down non-useful tissue and
glycogen.
Lysosomes
2/3

34. Lysosomes
3/3

35. Peroxisomes
Disarm highly reactive chemicals
with unpaired electrons that can
have devastating effects on the
cell.
Peroxisomes

36. Microtubules
Hollow tubes that determine the
overall shape of the cell
Move organelles around
Microtubules

37. Cilia
Hair
like cellular extensions that
move substances in one direction
Cilia

38. Flagella
Long projections that moves the
cell and not substances.

39. Nucleus
 Containhereditary unit of the cell
(genes) & genetic code (DNA).
the activity of the cell.
 Controls
 Has a membrane of its own called
nuclear envelope, that separates the
nucleus from the cytoplasm.
