The Animal Cell

1. Nucleus

1.1. Contains DNA of the cell and it directs the activities of the cell

2. Nucleolus

2.1. Small area within the nucleus where ribosomes are made

3. Nuclear Envelope

3.1. Similar to the cell membrane and surrounds the nucleus within the cell, porous and allows RNA and proteins to pass in and out

4. Endoplasmic Reticulum (Rough and Smooth)

4.1. Rough endoplasmic reticulum has ribosomes bound to its surface and modifies and transports the proteins made by the attached ribosomes

4.2. Smooth endoplasmic reticulum does not have attached ribosomes and modifies lipids and steroids.

5. Golgi Apparatus

5.1. Takes molecules produced by the cell, such as proteins and lipids, modifies them if necessary and packs them into vesicles so that they can be shipped around or outside of the cell

6. Ribosomes

6.1. Made of RNA and protein and are either attached to the endoplasmic reticulum or suspended in the cytosol, facilitate protein synthesis

7. Mitochondria

7.1. The site of cellular respiration in cells, which cells use for energy

8. Cell Membrane

8.1. The outer edge of the cell and forms the boundary between the inside of the cell with all of its organelles and the extracellular matrix

9. Cytoplasm

9.1. Thick, gel-like fluid that fills the space inside of a cell, and in which the organelles are suspended

10. Centrosomes

10.1. Centrosomes contain centrioles; the centrioles are small gatherings of microtubules that help with cell division during mitosis

11. Cytoskeleton

11.1. Composed of a network of filaments and tubules that allows the organelles of the cell to remain in place and gives the cell strength and shape

12. Vacuoles

12.1. Small storage pockets containing gas (such as oxygen or carbon dioxide) or fluid (such as water)

13. Lysosome

13.1. Specialized vesicles in which protein enzymes are contained, break down macromolecules into their components for further use by the cell
