Small agar cubes (agar is a seaweed-based, jello-like substance) and a colorimetric readout do you think that in this portion of the lab, you will be given a block of agar that you will cut into 3 sizes we will use these 3. For the initial lab, i make the agar in rectangular trays, like a wide silverware tray or a square pyrex dish make enough for 1-2 ice cubes per student or student group let agar harden at room temperature or in refrigerator. Research question: how does the size of the cell affect its efficiency in exchanging substances through several ways, like diffusion aim: to plan and carry out an investigation to show the relationship between volume/cm3, surface area, and diffusion using agar cubes measured in time/s and to demonstrate, using diffusion, why the size of cells.
Agar cube lab report
Agar cube lab report research question: how does the size of the cell affect its efficiency in exchanging substances through several ways, like diffusion aim: to plan and carry out an investigation to show the relationship between volume/cm3, surface area, and diffusion using agar bacteriology. Ap biology diffusion and osmosis lab report lily gao block 2 diffusion and osmosis lab report lily gao i introduction ii dry celery stick (not soaked in anything) lab 1b: 3 phenolphthalein agar cubes: 3x3x3 cm, 2x2x2 cm, and 1x1x1 cm, 1 plastic cup, ruler (6 metric system.
The naoh will continue to diffuse through the cube and gradually turn the inside of the cube pink the guiding question for this lab is thus: what determines the efficiency of diffusion throughout the model cells diffusion in agar cubes. Lab 4: diffusion and osmosis agar + potato = learning lab overview •we are doing two of them -procedure 1 and procedure 3 -procedure 1 is an investigation of diffusion through a cube of agar [s talk about the lab report. Biology: agar cube experiment evan kline loading want to watch this again later sign in to add this video to a playlist sign in share more report need to report the video sign in to report inappropriate cell size lab: cutting agar blocks - duration: 3:08 michelle. Agar cube measurements before diffusion: large: 3cm cubed the medium and large agar cubes remain pink towards the center because diffusion couldn't occur throughout the cube in the we are very confident with our results in this lab because all three cubes were soaked for the exact same. Please do not write on the lab handout cell size and diffusion lab your lab report needs to include: title, hypothesis, data table 1, cube drawings list the agar cubes in order of the ratios of surface area to volume from the largest ratio to the smallest ratio.
Diffusion lab overview the phenolphthalein in the agar cubes reacts with the naoh, changing the color of the cube to pink after the cubes are exposed to naoh. So in my biology 1 class, we did a lab called why are cells so small it had to do with surface area:volume ratio i've looked at other answers on ya, and they all had to do with this ratio what does it mean do cells want to be large do they want a large surface area. All biological cells require the transport of materials across the plasma membrane into and out of the cell by infusing cubes of agar with a ph indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells then, by observing cubes of different sizes, you can discover why larger cells might need extra. Growing bacteria in petri dishes take samples around you and see what bacteria will grow in an agar-filled petri dish this activity will prove that mom was right time for them to grow, too you need millions of them in one place just to see them at all they're really tiny in a lab. Surface area/volume lab compiled notes from pre-lab discussions/general feedback on written lab reports what pattern do we see when we look at absorption of a naoh solution into a model cell system made from agar cubes and a ph indicator independent variable: size of the cube.
