  1. Parts Of A Cell Organelles and their Functions

  2. This is a Cell.

  3. As you can see… • Though a cell is very small, there are things even smaller that make up the cell. • These small particles that make up the cell are called Organelles • There are several different types of Organelles and each has its own function.

  4. The Cell Membrane • Also called the Plasma Membrane • The cell membrane is made up of a permeable layer. • This layer allows certain things to pass through it, such as Oxygen, while it prevents other things from entering the cell. • The Cell Membrane surrounds the cell and is it’s boundary separating the inside of the cell, or cytoplasm, from the rest of the body.

  5. Mitochondria • The mitochondria of the cell is where a cell gets its power • Mitochondria oxidize foodstuffs to produce energy in the from of ATP • Mitochondria also have a special form of DNA that is passed down from mother to child. It is called Mitochondrial DNA • Power House of the Cell

  6. Lysosome • Lysosome are sacs filled with digestive enzymes. • The job of the lysosome is to digest worn out organelles, or the organelles that are no longer doing their job. • If ruptured, a lysosome can destroy the entire cell that it is a part of.

  7. The Endoplasmic Reticulum (ER) • There are 2 types of ER. Rough and Smooth. • Rough ER has ribosomes attached to it and is used to store and transport proteins to other parts of the cell. It also aids in protein synthesis • Smooth ER is used in transportation, but not synthesis.

  8. The Golgi Apparatus • Takes proteins that are delivered to it by the rough ER and modifies them, separates them, and then packages them into a membrane. • That membrane can then becomes part of the cell membrane, be excreted from the cell, or become a lysosome.

  9. Ribosome • Small round organelles that are made of RNA and protein. • Site of protein synthesis for the cell. • Can be found free floating or attached to the rough ER.

  10. Nucleus • Contains the genetic material for the cell, or the DNA. • Known as the “Control Center of the Cell” • Necessary for cell reproduction and replication • Has a membrane much like the cell membrane called the nuclear membrane or nuclear envelope.

  11. Cytoplasm • Cytoplasm is what makes up the inside of the cell. • It is a fluid that contains the other organelles floating in it along with the organelles. • The liquid alone is called cytosol.

  12. Cytoskeleton • Used to support the cell. • Made of 3 types: Mictrotubules, Microfilaments, and Intermediate filaments. • Helps determine shape of the cell.
