1. Where did the term \u00c3\u00a2\u00e2\u201a\u00ac\u00c5\u201ccells\u00c3\u00a2\u00e2\u201a\u00ac\u00c2\u009d come from? Who coined the term for the use it has in science today?<\/span><\/td>\nRobert Hooke thought that they (cells) looked like monastery rooms. \u00c3\u201a\u00c2\u00a0They were called cells.<\/span><\/td>\n<\/tr>\n
2. What is the cell theory?<\/span><\/td>\nAll plants and animals are made up of cells, and new cells can only be made up of old cells. <\/span><\/td>\n<\/tr>\n
3. What are the strengths and weaknesses of compound light microscopes? What can and can\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t they be used for?<\/span><\/td>\nA strength is that it is very clear up to 1000 times the size of an original, and that they are more portable than other kinds. \u00c3\u201a\u00c2\u00a0A weakness is that to usually have to dye an organism to view it. \u00c3\u201a\u00c2\u00a0It can be used for thin things, but not thicker things.<\/span><\/td>\n<\/tr>\n
4. What are the strengths and weaknesses of electron microscopes? What can and can\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t they be used for?<\/span><\/td>\nA strength of an electron microscope is that it has a much stronger magnification, it can be used to see DNA and viruses. \u00c3\u201a\u00c2\u00a0A weakness is that everything must be in a vacuum, so organisms can\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t be live. <\/span><\/td>\n<\/tr>\n
Compare AND contrast<\/b> prokaryotes and eukaryotes. Name at least two similarities and three differences.<\/span><\/td>\nSIMILARITIES<\/span><\/p>\n

Both are cells<\/span><\/p>\n

Both have DNA<\/span><\/p>\n

DIFFERENCES<\/span><\/p>\n

Prokaryotes are usually much smaller<\/span><\/p>\n

Prokaryotes do not separate the genetic material with a membrane (no specific nucleus)<\/span><\/p>\n

Eukaryotes are usually more complex<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

1. What is an organelle? Why don\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t you think cytoplasm is considered an organelle?<\/span><\/td>\nOrganelles are organ like features inside a Cell. \u00c3\u201a\u00c2\u00a0Cytoplasm is just water so it does not do anything to benefit the cell.<\/span><\/td>\n<\/tr>\n

    7.3 Cell Transport<\/b><\/p>\n

    Questions<\/b> Answers<\/b><\/p>\n\n\n\n\n\n\n\n\n\n\n
    1. What is diffusion? Give an example of diffusion that you might see in your everyday life.<\/span><\/td>\nDiffusion if when molecule go down a concentration gradient and evenly spread molecules. \u00c3\u201a\u00c2\u00a0An example would be dye filling \u00c3\u201a\u00c2\u00a0a jar of water.<\/span><\/td>\n<\/tr>\n
    2. If there is a higher concentration of molecules on the outside of the cell than on the inside, will diffusion cause those molecules to travel into or out of the cell (see figure 7-15)<\/span><\/td>\nThe particles will enter the cell.<\/span><\/td>\n<\/tr>\n
    3. Compare and contrast diffusion and facilitated diffusion<\/span><\/td>\nBoth don\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t take any energy to complete. \u00c3\u201a\u00c2\u00a0Both bring molecules through a membrane. \u00c3\u201a\u00c2\u00a0Facilitated diffusion has a protein bring a polar molecule through since it can\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t go through the membrane.<\/span><\/td>\n<\/tr>\n
    4a. Why are aquaporins necessary?<\/span><\/p>\n

    4b. What is osmosis? <\/span><\/td>\n

    		\n
      \n
    1. Aquaporins are necessary because they allow water to flow in freely.<\/span><\/li>\n
    2. Osmosis is diffusion but with water. \u00c3\u201a\u00c2\u00a0Its water making a concentration equal by passing through a membrane.<\/span><\/li>\n<\/ol>\n<\/td>\n<\/tr>\n
    The terms \u00c3\u00a2\u00e2\u201a\u00ac\u00c5\u201chypotonic\u00c3\u00a2\u00e2\u201a\u00ac\u00c2\u009d and \u00c3\u00a2\u00e2\u201a\u00ac\u00c5\u201chypertonic\u00c3\u00a2\u00e2\u201a\u00ac\u00c2\u009d are simply adjectives that describe how concentrated an environment in solution is. <\/span><\/p>\n

    5a. If the inside of a cell is hypertonic compared to the outside of the cell, and the solute cannot pass through the membrane, which direction will water go? Into or out of the cell?<\/span><\/p>\n

    5b. What is meant by isotonic? <\/span><\/p>\n

    5c. Explain the importance of osmotic pressure in plants.<\/span><\/td>\n

    		\n
      \n
    1. The water will enter the cell, as in go inside of it.<\/span><\/li>\n
    2. Isotonic means that there is an equal amount of water on both sides of the membrane.<\/span><\/li>\n
    3. If there is too much osmotic pressure in a plant cell, the vacuole will grow and push organelles out of the cells.<\/span><\/li>\n<\/ol>\n<\/td>\n<\/tr>\n
    6. What is active transport? What molecule do you think powers this type of transport?<\/span><\/td>\nActive transport is when protein pumps bring molecules through the membrane against the gradient flow. ATP powers this transport.<\/span><\/td>\n<\/tr>\n
    7. Under what conditions might active molecular transport occur? Why won\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t regular diffusion or active diffusion work?<\/span><\/td>\nThe cell might need lots of a certain thing. \u00c3\u201a\u00c2\u00a0Regular things won\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t work because it goes against the concentration gradient.<\/span><\/td>\n<\/tr>\n
    8. Compare and contrast endocytosis and exocytosis. Try to think of a trick to remember the difference between these terms!<\/span><\/td>\nEndocytosis is like the cell is eating it wraps the membrane around a large molecule and bring in into the cell. \u00c3\u201a\u00c2\u00a0Exocytosis is when a vesicle fuses with the membrane and explels something.<\/span><\/p>\n

    1. How do unicellular organisms maintain homeostasis?<\/span><\/td>\nThey grow and respond to the environment, they reproduce via mitosis, and they transform energy.<\/span><\/td>\n<\/tr>\n
    2a. How are individual cells within a multicellular organism different from single-celled organisms?<\/span><\/p>\n

    2b. Describe, in your own words, examples of specialized cells in animal and plants<\/span><\/td>\n

    		\n
      \n
    1. In multicellular organisms, cells are specialized to do a certain job. \u00c3\u201a\u00c2\u00a0In single celled, they respond to the environment directly. \u00c3\u201a\u00c2\u00a0<\/span><\/li>\n
    2. In an animal, hemoglobin is an example of \u00c3\u201a\u00c2\u00a0a specialized cell. \u00c3\u201a\u00c2\u00a0In plants, pollen is an example, it has \u00c3\u00a2\u00e2\u201a\u00ac\u00cb\u0153wings\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2 so it can fly to the ground.<\/span><\/li>\n<\/ol>\n<\/td>\n<\/tr>\n
    3. Explain the relationship between cells, tissue, organs and organ systems. Use any multicellular organism as an example in your explanation. <\/span><\/td>\nblood cells are in veins and arteries, those are part of the heart, which is part of the circulatory system.<\/span><\/td>\n<\/tr>\n
    4. What is a receptor? Why are receptors so important?<\/span><\/td>\nSomething to which a signaling molecule can bind to. \u00c3\u201a\u00c2\u00a0It allows certain molecules go to places that they are needed the most by letting them only in those places.<\/span><\/td>\n<\/tr>\n
