3. Chapter 7: Cell Structure and Function

4. What are cells???
Cells are the basic units of life.

5. Cell Theory All living things are made up of cells
Cells are the basic units of structure and function in living things
New cells are produced from existing cells

6. Organelles
Eukaryotic cells have specialized substructures, called organelles, carry out the essential functions of life.
“little organs”
Chart, flashcards, or notes  your choice!

7. Eukaryotic Cells
Animals and Plants

8. Organelles
The cytoplasm is the semi-fluid material that contains the organelles

9. Organelles
The cell membrane is the thin flexible barrier surrounding a cell
Phospholipid bilayer
Regulates what enters and leaves the cell
Selectively permeable membrane
Protects and supports the cell

10. Organelles
The nucleus contains the chromosomes which are composed of DNA (deoxyribonucleic acid, a chemical compound that stores and transmits genetic information) and functions as the genetic control center of the cell

11. Organelles
A chromosome is a structure in the nucleus of a cell consisting essentially of one long thread of DNA that is tightly coiled.

12. Organelles
The cytoskeleton is a network of fibrous proteins that helps the cell with maintaining shape, support, and movement.

13. Organelles
Endoplasmic reticulum (ER) is a complex, extensive network that transports materials throughout the inside of a cell.
Rough ER has ribosomes
attached to the surface.
Smooth ER
has no
ribosomes

14. Organelles
Ribosomes are the sites of protein synthesis; some are located on the ER, others are found in the cytoplasm.

15. Organelles
The Golgi complex/ apparatus modifies, collects, packages, and distributes proteins and other materials to be used within or outside the cell.

16. Organelles
Lysosomes break down lipids, carbohydrates, and proteins into small molecules that can be used by the cell.

17. Organelles
Vacuoles store materials like water, salts, proteins, and carbohydrates.

18. Organelles
Vesicles are smaller structures that store and move materials between cell organelles, as well as to and from the cell surface.

19. Organelles Mitochondria supply the energy for the cell
Converts chemical energy stored in food into usable energy for the cell

23. Proteins
Cellular processes are carried out by molecules. Proteins carry out most of the work of cells to perform the essential functions of life. One of the major functions of the cell is the production of proteins. The genetic information in DNA provides instructions for assembling protein molecules. In eukaryotic cells the nucleus, ribosomes, endoplasmic reticulum, vesicles, and the Golgi apparatus interact to produce, modify and transport proteins.
