| Question | Answer |
|---|---|
| Part 1 of Cell Theory | All living things are composed of one or more cells. |
| Part 2 of Cell Theory | Cells are the basic units of structure and function in organisms. |
| Part 3 of Cell Theory | All cells come from preexisting cells by cell division. |
| Why can't a cell survive if it gets too large? | It won't be able to get the nutrients (food) it needs to survive fast enough, and therefore it's too large to survive |
| Cell cycle stage - Cell had 1st growth, organelles are reproducing | G1 |
| Cell cycle stage - DNA replicates | S |
| Cell cycle stage - Cell has 2nd growth, and checks DNA replication | G2 |
| Cell cycle stage - Nucleus divides (DNA) | Mitosis |
| Cell cycle stage - Cytoplasm and organelles divide | Cytokinesis |
| What are G1, S, and G2 collectively (all together) called? | Interphase |
| Cell Cycle Term - DNA | Genetic instructions for cell, codes for traits |
| Cell Cycle Term - Chromatin | DNA coiled around a histone protein, long thin strands of DNA |
| Cell Cycle Term - Chromosomes | Coiled up chromatin, best form of DNA for dividing |
| turns food energy into chemical energy (cellular respiration) | Mitochondria |
| contains enzymes to clean up wastes in the cell | Lysosome |
| contains DNA | Nucleus |
| in plants only, provides structure and support | Cell Wall |
| makes large amounts of protein | Rough endoplasmic reticulum |
| makes fats and carbohydrates | Smooth endoplasmic reticulum |
| proofreads, packages, and delivers proteins | Golgi Body |
| stores water, small in animals | Small vacuole |
| stores water, large in plants | Large Vacuole |
| in plants only, turns sunlight energy into chemical energy | Chloroplast |
| allows certain materials in and out of the cell, flexible | Cell Membrane |
