Cell Organelles

What makes up the cell membrane? 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?

Plant Cell

Animal Cell
