a. the larger the concentration gradient, the faster the rate of diffusion b. the rate depends on the size of the molecule c. the smaller the concentration gradient, the faster the rate of diffusion d. simple diffusion occurs at a faster rate than facilitated diffusion Short Answer 1. (a) Label the organelles shown in the diagram. (b) Is the cell a plant cell or an animal cell? How do you know? (2 marks) 2. Explain the theory of endosymbiosis. Do you think this theory is plausible? Why? (2 marks) 3. Compare the structure and function of a mitochondrion and a chloroplast. (2 marks) 4. What is the fluid mosaic model? Do you think that this name is accurate? (2 marks) 5. What is membrane asymmetry and why is it an important characteristic of membranes? (2 marks) 6. How do the positions of the membrane proteins relate to their functions? (2 marks)

This causes water to move into the cell through osmosis, leading to the cell swelling and potentially bursting. Show more…

1. Define hypertonic, isotonic, and hypotonic solutions. Compare and contrast what would happen to an animal cell and a plant cell if submerged in each of the three solutions. 2. Using your own words, define diffusion, osmosis, and concentration gradient. Please be as detailed as possible.

Please view the above videos and answer the following questions. This is an exercise in the movement of substances across a selectively permeable membrane, to illustrate how the cell membrane operates within the cells of our bodies. If the integrity of the cell membrane is destroyed, the cell will perish. 1. Describe in your own words the concepts of diffusion and osmosis. 2. Hemolysis and Crenation. Describe in your own words what happens to a red blood cell when placed in a hypertonic solution, an isotonic solution and a hypotonic solution. How does this relate to dehydration? 3. Define the following organelles, name their primary function: a. Nucleus b. Mitochondria c. Golgi Complex d. Lysosome e. Cilia and flagella f. Ribosomes g. Plasma/Cell Membrane 4. Be able to label all the parts of a cell on a diagram. Study the diagram from the Lab or Lecture book.
1. Define osmosis. 2. Characterize isotonic, hypertonic, and hypotonic solutions and explain what happens to cells osmotically in each of these environments. 3. State which tonicity is optimal for animal cells and explain why. 4. State which organs maintain optimal extracellular fluid tonicity.
