Bell Ringer What makes up the cell membrane?
Nucleus • Controls the Cell • Surrounded by a Nuclear Envelope • Contains DNA • Covered by Nuclear Pores
Endoplasmic Reticulum • An extensive system of internal membranes that move proteins and other substances through the cell • 2 Types • Rough ER • Smooth ER
Rough ER • Covered in Ribosomes • Helps transport the proteins that are made by its attached ribosomes. • Proteins cross the Rough ER Membrane and pinch off to form a vesicle.
Vesicle • Small membrane bound sac that transports substances in cells.
Smooth Endoplasmic Reticulum • Lacks Ribosomes • Smooth ER makes lipids and breaks down toxic substances
Packaging Proteins • Newly packaged proteins move from the ER to the Golgi Apparatus • Golgi Apparatus – set of flattened membrane bound sacs that serve as the packaging and distribution center of the cell • Enzymes inside the golgi modify the proteins, which then are enclosed in new Vesicles that bud from the surface of the golgi apparatus
Lysosomes • Type of vesicle that contain a cells digestive enzymes • Made by the golgi apparatus and digest worn out particles, bacteria, or viruses found in the cell
Groups! • List and determine the steps of packaging the distribution of proteins
Mitochondria • Harvests energy from organic compounds to make ATP. • Mitochondria have a large surface area. • A folded inner membrane of the mitochondria is where production of ATP occurs.
Mitochondria • Why would muscle cells contain high amounts of mitochondria?
Plant vs Animal Cell • List three differences between plant and animal cells
Plant • Plant cells have three additional structures than animal cells • 1. Cell Wall • 2. Chloroplasts • 3. Central Vacuole
Cell Wall • Surrounds the cell membrane • Composed of Proteins and Carbohydrates • Helps support and maintain shape of cell • Connects it to adjacent cells
Chloroplasts • Organelles that use light energy to make Carbohydrates from Carbon Dioxide and Water
Central Vacuole • Stores water in the cell • What happens when this is full/empty?
