1. The Cell Organelles (Typical Animal Cell)
Cell Organelles are small structures that help carry out life functions
Cell Membrane
Nucleus
Endoplasmic Reticulum
Ribosomes
Golgi Body
Lysosome
Mitochondria
Vacuoles

2. Cell Membrane
The cell membrane separates the cell from its surrounding environment, The membrane controls the movement of materials into and out of the cell. This makes it possible for the cell contents to be chemically different from the environment.
It is described as “selectively” or “semi” permeable because not all things can go through

3. Lipid Bilayer
Protein Channel
Enzyme
Protein Receptor

4. Nucleus
The control center for metabolism and reproduction. Houses the genetic information (chromosomes).

Nucleus
Real under electron Microscope

6. Endoplasmic Reticulum
System of fluid-filled canals, or channels, enclosed by membranes. Serve as paths to transfer materials throughout the cell.

7. Rough Endoplasmic Reticulum
(Rough = with Ribosomes)
Ribosome
Endoplasmic Reticulum
RER or ER (without ribosomes)
The Real Thing

8. The site of protein synthesis.
Ribosomes
The site of protein synthesis.
These Ribosomes are colored enhanced.
They can be found on the ER or floating in the cytoplasm

9. These two organelles often work together
Golgi bodies
Golgi bodies aid in the preparation and storage of molecules to be secreted by the cell. Proteins made at ribosomes are often packaged by the Golgi complex
These two organelles often work together
R.ER
Golgi body

10. Golgi In Action
Outside Cell
Inside Cell

11. Involved in the digestion of food with in the cell.
Lysosomes
Involved in the digestion of food with in the cell.
They contain enzymes - they will eventually combine with food vacuoles to digest food. Sometimes they are opened up and destroy worn-out cells

12. Releases energy stored in food molecules (cellular respiration).
Mitochondria
Releases energy stored in food molecules (cellular respiration).
Food = chemical bond energy = organic molecule
Cellular Respiration
Taking energy out of food and converting it into a form that can be used by the cell (ATP)

14. Storage site for cell products (water, food, waste products)
Vacuole
Storage site for cell products (water, food, waste products)

15. Plant Cell

16. (Adds Structural Support)
Cell Wall
Lies just outside the cell membrane, and gives the cell its shape and provides protection for the cell.
(Adds Structural Support)
Mainly made of the carbohydrate called cellulose

17. Large Vacuole
Plant cells have large vacuoles that are typically used as a storage site for waste products.
Very Large

18. The green pigment captures the light energy
Chloroplast
The place where photosynthesis takes place. They are green because they contain a green pigment called - chlorophyll
The green pigment captures the light energy
