Cell Organelles Bell Ringer What makes up the cell membrane? Nucleus Nucleus Controls the Cell Surrounded by a Nuclear Envelope Contains DNA Covered by Nuclear Pores Endoplasmic Reticulum 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 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 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?
