1. III. Prokaryotes Vs. Eukaryotes CELLS ProkaryoticEukaryotic No True Nucleus - Genetic material is free-floating in cytoplasm. No specialized organelles Contain specialized organelles True Nucleus - Genetic material is bound by a membrane EX: BacteriaEX: Human Cells SmallerLarger

3. Animal Cell

4. Plant Cell Cell wall

5. IV. Cell Structures & Organelles StructureFunction/Other Info Cell Wall Support & protection Lies outside cell membrane Not in animal cells Cell Membrane Regulates what enters/ leaves the cell (selectively permeable) *Transport & Excretion Plants – cellulose

6. StructureFunction/Other Info Nucleus Controls most cell processes Contains hereditary information (DNA) Dense nucleolus produces ribosomes *Regulation Cytoplasm Watery fluid between membrane and nucleus that contains organelles

7. StructureFunction Endoplasmic Reticulum Transport* materials throughout cell Rough ER has ribosomes attached (Smooth ER doesn’t) Ribosome PROTEIN SYNTHESIS*

9. StructureFunction Vacuole Stores food, water, wastes Large in plant cells; Small in animal cells Centrioles Help separate chromosomes during cell division (reproduction) Animal cells only Lysosome Breaks down (digest) food and old organelles Animal cells only *Nutrition

10. StructureFunction Mitochondria “Powerhouse” Release energy from glucose to produce ATP (aerobic respiration*) Chloroplast Use energy from sunlight to make glucose & oxygen (photosynthesis) Not in animal cells Contains chlorophyll (green pigment) to absorb sunlight *Nutrition
