1. CH 3 Section 3 Cell Organelles

2. Nucleus Controls most cellular functions Double membrane with nuclear pores Ribosomes made Stores DNA (chromosomes in cell division)

3. Ribosome and Endoplasmic Reticulum Part of the internal membrane system –Highway system of the cell Ribosomes attached for protein production (Rough) –Protein transported in a vessicle No ribosomes= smooth –used in lipid production and detoxification

4. Golgi Apparatus Packing and Distribution Accepts vesicles from ER Enzymes make final modifications to proteins Final product repackaged in a new vesicle –Vesicle may stay in the cell such as the LYSOSOME –Vesicle may move to the membrane and release its contents

5. Mitochondria Powerhouse of the cell –ATP production Double membrane structure –inner membrane space and a matrix –Inner membrane is the site of most ATP production Mitochondria have their own DNA that is inherited only from the female parent Were mitochondria an independent cell at one time?

6. How plant cells differ from animal cells Cell wall made of cellulose provide structure Chloroplasts aid in photosynthesis –Also contain their own DNA Have a large central vacuole to store water nutrients and waste –Provides turgor pressure
