| Question | Answer |
| what are cells | the smallest structural and functional unit of an organism |
| name two types of cells | prokaryotic and eukaryotic |
| name the differences and the similarities of prokaryotic and eukaryotic cells | |
| label this cell | |
| what is the function the nucleus | protects DNA controls cell |
| what is the function of ribosomes | builds proteins |
| what is the function of the Golgi apparatus | finishes, packages and ships proteins |
| what is the function of the endoplasmic reticulum (ER) | helps finish proteins makes membrane |
| what is the function of the cell membrane | cell boundaries controles movement in and out of the cell |
| what is the function of mitochondria | makes ATP energy from sugars and oxygen (O2) |
| what is the function of the centrioles | cell devision |
| what is the function of vacuoles and vesicles | transport inside the cell strorage |
| what is the function of cytoplasm | jelly-like material holding the organelles in place |
| what is the function of lysosome | food digestion |
| label this diagram |

|
| name the differences and similarities between plant cells and animals cells | |
| what is the function of chloroplast | makes ATP and sugars in photosynthesis |
| what is the function of the cell wall | support |
| what is the function of the central vacuole | storage: food, waste or water |
| label this diagram | |
| name 4 types of microscopes | - compound - simple - stereoscopic - electron |
| how do you calculate the power of the objectives | multiply the power of the ocular lens by the power of the objective |
| how do you put a specimen on a microscope name the steps in order | 1. plug in the microscope and turn on the lamp 2. put the specimen in the centre of the slide 3. place a cover slip over the specimen 4. place the specimen on the stage and adjust it so it is over the opening on the stage 5. raise the stage while looking at the stage from the side 6. look into the eye piece and use the case adjustment to make the specimen more focused 7. use the fine adjustment to sharpen the focus |
| what do cells input | energy and matter |
| what do cells output | gasses, simple nutrients, iron, water |
| name two types of transports | active and passive transport |
| what is active transport | cell uses energy actively moves molecules to where they are needed movement to an area whit a low concentration to an area with a high one |
| what is passive transport | cell does not use energy molecules move randomly molecules move from an area of high concentration to low concentration |
| name three types of passive transport | diffusion facilitated diffusion osmosis |
| what is diffusion | random movements of parties from an area with a high concentration to an area with a low concentration |
| what does equilibrium mean | diffusion continues until the particles are evenly spread out tisanes called the equilibrium (the particles do not stop moving they are just spread out) |
| what is facilitated diffusion | diffusion of specific particles through transport proteins found in the membrane |
| what is osmosis | diffusion of water though a selectively permeable membrane |
| what is a hypotonic solution | the solution has a lower concentration of solutes and a higher concentration of water |
| what is a hypersonic solution | this solution has a lower concentration of solutes and a lower concentration of water |
| what is a isotonic solution | the concentration of the solutes in the solution is equal to the concentration inside the cell |
| label this diagram | |
| what is cellular reparation | the process of using glucose to make energy autotrophes and heterotrophs |
| what is photosynthesis | light energy converted to chemical energy of organic compounds autotrophs only |
| why do cells need glucose and oxygen | oxygen and glucose react together in cells and create carbon dioxide and water |
| where does cellular respiration occur | in the cytoplasm then the mitochondria |
| what is the word formula for cellular respiration | glucose + oxygen = carbon dioxyde + water + ATP |
| what is the chemical formula for cellular respiration | C6H1206 + O2 = CO2 + H2O + ATP |
