- Cell Structure
- Organelles Working Together
- Protein Production
- Proteins made at ribosom
- RER make proteins that are excreted or attached to cell membrane
- New proteins folded and processed in ER
- Then transported to the Golgi apparatus in vesicles
- Further Processing
- Enter more vesicles to be transported around the cell
- Further Processing
- Then transported to the Golgi apparatus in vesicles
- New proteins folded and processed in ER
- Free ribosomes make proteins that stay in the cytoplasm
- RER make proteins that are excreted or attached to cell membrane
- Proteins made at ribosom
- Protein Production
- Prokaryotic Cells
- Extremely small cells (tenth the size of eukaryotic cells
- DNA is circular
- No nucleus - DNA free in cytoplasm
- Cell wall made of polsaccharide, but no cellulos or chitin
- Few organelles, no mitochondria
- small ribosome
- Studying Cells - Micropsopes
- Resolution = how detailed the image is
- Light Microscope
- Use Light
- Lower Resolution : 0.2 micrometres
- Max magnification is about x 1500
- Electron Miscroscopes
- Eclectorons
- Transmission electron microscope (TEM)
- Higher resolution
- Thinner Specimens
- Eukaryotic Cells and Organelles
- Eukaryotes
- Plant Cell
- Mitochondrian
- Rough Endoplasmic Reticulum
- Plasma Membarne
- Ribosome
- Cell Wall
- Chloroplast
- Vacuole
- Plasmodesmata
