Osmosis & Diffusion Review Sheet Name: Fill in the Blank away low high hypertonic hypotonic diffusion molecules osmosis vacuole water solute permeable towards semi-permeable concentration gradient 1. The cell membrane regulates and controls what kind of molecules ______ move in & out of the cell. 2. When molecules spread from an area of high to low concentration‚ it is called _Diffusion_____. 3. As molecules diffuse‚ they create a _concentration gradient_____

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Review Sheet Exercise I: Survey of Higher Microorganisms: Protozoa‚ Fungi‚ and Helminths Protozoa (group of Kingdom Protista) 1. Amoeba a. nucleus- dark center of the cell b. food vacuole- They feed by taking nutrients into the cell by diffusion and packaging it into (clear circles spread throughout the cell) c. pseudopod- “false foot”; the motility results from the streaming of the protoplasm that forms the process 2. Entamoeba causes amoebiasis or amoebic dysentery‚

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not be

REVIEW SHEET EXERCISE 12 Serological Testing NAME: LAB TIME/DATE: Positive and Negative Controls 1. Why are there a number of washing steps in serological tests? They are needed in order to remove any non specific binding that may happen. 2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of your results? If it has a negative control then it’s a false positive so the results are invalidated. 3. Describe how you would

three main parts of a cell. plasma membrane-forms a cell’s flexible outer surface‚ separating the cell’s internal environment (inside the cell) from its external environment (outside the cell) cytoplasm- consists of all the cellular contents between the plasma membrane and the nucleus. nucleus- is the largest organelle of a cell. The nucleus acts as the control center for a cell because it contains the genes‚ which control cellular structure and most cellular activities The cell is the basic‚ living

ACTIVITY 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. __The size and the concentration. ___ 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your
