1. Cell Organelles

2. PARTS OF A CELL Plasma (cell) membrane Cell Wall Cytoplasm Nucleus
Nuclear membrane
Ribosomes
Endoplasmic Reticulum
Golgi Apparatus
Mitochondria
Lysosome
Vacuole
Chloroplasts

3. Plasma Membrane

4. The Plasma Membrane is like the SKIN of the cell.
The Cell Membrane controls what
enters and leaves the cell. .

5. Nucleus

6. The Nucleus is like the BRAIN of the cell.
The nucleus is the control center
of the cell.
It contains the genetic information
for the cell in the form of DNA
called chromatin.
It is a membrane bound structure
usually found in the middle of the cell.

7. The Mighty
Mitochondria

8. The “Mighty” Mitochondria is the POWERHOUSE of the cell.
Mitochondria - Makes energy in the form of ATP
ATP are produced to “power” the cell.

9. Endoplasmic Reticulum

10. The Endoplasmic Reticulum is the cells DELIVERY SYSTEM.
Endoplasmic Reticulum (ER) - Delivers proteins.
A membranous tubular system
throughout the cell connecting
the nuclear membrane to the
cell membrane.

11. Golgi Apparatus

12. The Golgi Apparatus is the PACKAGING CENTER of the cell.
Golgi Apparatus - Packages and modifies proteins.

13. Vacuoles

14. Vacuoles are the STORAGE SPACES for cells.
These are membranous sacs that can store food, enzymes, wastes, and other materials needed by the cell.
Plant cells have large vacuoles for water storage.

15. Lysosomes
Specialized vacuole that contains digestive enzymes.

16. Ribosomes
Protein synthesis (makes proteins)

17. Cytoplasm
Jello-like substance where organelles are embedded.

18. Centrioles

19. Centrioles Centrioles help in cell division.
They are found only in animal cells.

20. Cell Wall

21. The Cell Wall is like a suit of ARMOR around the cell.
Cell Wall - Supports the cell.
It is found in plant cells
NOT animal cells.

22. Chloroplast

23. Chloroplasts are where PHOTOSYNTHESIS occurs.
Contain chlorophyll, a green pigment
that traps the energy from light.
Found in plant cells and some protists,
NOT found in animal cells.

24. Differences in Plant Cells & Animal Cells

25. Plant Cells have a cell wall large vacuoles for water storage
chloroplasts for photosynthesis

26. Centrioles for cell division
Animal Cells
Vacuoles are smaller
Centrioles for cell division

29. DIVISION OF LABOR
Many celled organisms are called MULTI-CELLULAR. One cell within an organism may be adapted for movement, while another cell carries out digestion. Cell specialization allow the individual cells to depend on each other rather than trying to carry out all life functions (division of labor).

30. LEVELS OF ORGANIZATION
Multi-cellular organisms are made up of cells, tissues, organs, and then, organ systems.
Ex. Bone cell, bone tissue, the bone is an organ, all the bones form the skeletal system which is a part of the 13 systems that make up a human.

31. CELL TRANSPORT PASSIVE TRANSPORT DO NOT REQUIRE ENERGY FROM THE CELL.
ACTIVE TRANSPORT
REQUIRES ENERGY BY THE CELL.

32. PASSIVE TRANSPORT DIFFUSION
The movement of particles from an area of high concentration to a low concentration.
OSMOSIS
The diffusion of WATER molecules.
Example of Diffusion: coffee aroma

33. ACTIVE TRANSPORT
Substances move from an area of low concentration to an area of high concentration.
Transport of materials against a “concentration gradient” requires energy.
