| Question | Answer |
| Cell theory (3) | 1. Cell is basic unit of life 2. All organisms have at least one cell 3. All cells come from other cells. |
| Prokaryotic cell characteristics (4) | -no nucleus -circular (loop) DNA -no membrane enclosed organelles -enclosed by plasma membrane (encased in rigid cell wall) |
| Characteristics of Eukaryotic cells (4) | -larger and more complex -true nucleus -many membrane bound organelles -linear DNA |
| Cell membrane | -Contact/interact with environment -regulate transport in/out |
| Rough er | -Manufactures membranes -ribosomes of er produces proteins |
| Smooth er | -Synthesizes lipids -regulate carbohydrate metabolism -break toxins and drugs |
| Golgi | Receive and modify ER products, send to other organelles or to cell membrane . |
| Lysosomes | -digestive enzymes in membrane sacs bud from golgi -damaged / dead cell parts -destroy bacteria -digest food -apoptosis (damaged, infected, cancerous, embryonic development) |
| Large central vacuole | -in plants - gives cel support ; stores water -has lysosomal and storage functions |
| Endosymbiotic theory and evidence (4) | -mitochondria evolved from prokaryotes Evidence : -own DNA (circular, sequence similar to prokaryotes) -have own ribosomes that resemble bacterial ribosomes -divide by binary fission -Inner membrane chemically resembles bacterial membrane |
