- 1what are cellsthe smallest structural and functional unit of an organism
- 2name two types of cellsprokaryotic and eukaryotic
- 3name the differences and the similarities of prokaryotic and eukaryotic cells
- 4label this cell
- 5what is the function the nucleusprotects DNA controls cell
- 6what is the function of ribosomesbuilds proteins
- 7what is the function of the Golgi apparatusfinishes, packages and ships proteins
- 8what is the function of the endoplasmic reticulum (ER)helps finish proteins
makes membrane - 9what is the function of the cell membranecell boundaries
controles movement in and out of the cell - 10what is the function of mitochondriamakes ATP energy from sugars and oxygen (O2)
- 11what is the function of the centriolescell devision
- 12what is the function of vacuoles and vesiclestransport inside the cell
strorage - 13what is the function of cytoplasmjelly-like material holding the organelles in place
- 14what is the function of lysosomefood digestion
- 15label this diagram
- 16name the differences and similarities between plant cells and animals cells
- 17what is the function of chloroplastmakes ATP and sugars in photosynthesis
- 18what is the function of the cell wallsupport
- 19what is the function of the central vacuolestorage: food, waste or water

- 21name 4 types of microscopes- compound
- simple
- stereoscopic
- electron - 22how do you calculate the power of the objectivesmultiply the power of the ocular lens by the power of the objective
- 23how do you put a specimen on a microscope name the steps in order1. 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 - 24what do cells inputenergy and matter
- 25what do cells outputgasses, simple nutrients, iron, water
- 26name two types of transportsactive and passive transport
- 27what is active transportcell 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 - 28what is passive transportcell does not use energy
molecules move randomly
molecules move from an area of high concentration to low concentration - 29name three types of passive transportdiffusion
facilitated diffusion
osmosis - 30what is diffusionrandom movements of parties from an area with a high concentration to an area with a low concentration
- 31what does equilibrium meandiffusion continues until the particles are evenly spread out tisanes called the equilibrium (the particles do not stop moving they are just spread out)
- 32what is facilitated diffusiondiffusion of specific particles through transport proteins found in the membrane
- 33what is osmosisdiffusion of water though a selectively permeable membrane
- 34what is a hypotonic solutionthe solution has a lower concentration of solutes and a higher concentration of water
- 35what is a hypersonic solutionthis solution has a lower concentration of solutes and a lower concentration of water
- 36what is a isotonic solutionthe concentration of the solutes in the solution is equal to the concentration inside the cell
- 37label this diagram
- 38what is cellular reparationthe process of using glucose to make energy
autotrophes and heterotrophs - 39what is photosynthesislight energy converted to chemical energy of organic compounds
autotrophs only - 40why do cells need glucose and oxygenoxygen and glucose react together in cells and create carbon dioxide and water
- 41where does cellular respiration occurin the cytoplasm then the mitochondria
- 42what is the word formula for cellular respirationglucose + oxygen = carbon dioxyde + water + ATP
- 43what is the chemical formula for cellular respirationC6H1206 + O2 = CO2 + H2O + ATP
