Question

1. match the following organelles to their function or structure. note: each organelle is only used once. (4 pts) 1. controls the passage of materials into and out of a cell. 2. protects dna. 3. makes proteins. 4. modifies and packages proteins 5. produce energy in the form of atp. 6. digest foreign substances and worn - out cell parts. 7. structures shaped like small oars that beat in unison to move the cell or the liquid around it. 8. acts as a whipping propeller, moving a cell through its environment. a. cell membrane b. flagella c. lysosomes d. mitochondria e. ribosomes f. cilia g. nucleus h. golgi apparatus concept 2 multiple choice (2 pts each) 12. what type of cellular transport requires a cell to use energy? a. facilitated diffusion b. active transport c. diffusion d. osmosis 13. this process occurs when the cell uses energy to bring something in from outside the cell. a. endocytosis b. exocytosis c. osmosis d. diffusion 14. in a hypotonic solution, water will move __ the cell, causing the cell to __. a. into; shrivel b. out of; lyse/swell c. out of; shrivel d. into; lyse/swell 15. if an animal cell were placed in a solution of salt water taken from the ocean, what would happen to the cell? a. the cell would swell because the water solution is hypertonic. b. the cell would swell because the water solution is hypotonic. c. the cell would shrivel because the water solution is hypotonic. d. the cell would shrivel because the water solution is hypertonic. 16. which of the following best describes an isotonic solution? a. there is more solute outside the cell than inside the cell. b. there is less solute outside the cell than inside the cell. c. the concentration is equal on both sides of the membrane. d. none of the above. concept 2 open response for the following situations, name which specific type of transport would be used. we discussed 6 specific types of cell transport. do not just write active or passive. (4 pts) a.) transporting o2 and co2. b.) transporting glucose. c.) when a white blood cell captures bacteria. d.) transporting water 18. next to each statement below, write “a” if it refers to active transport or “p” if it refers to passive transport. (4 pts) a.) requires energy b.) moves particles from an area of higher concentration to an area of lower concentration c.) used to transport water d.) moves particles against the concentration gradient from areas of lower concentration to higher concentration.

Explanation:

11.

1. A. Cell membrane controls material passage.
2. G. Nucleus protects DNA.
3. E. Ribosomes make proteins.
4. H. Golgi apparatus modifies and packages proteins.
5. D. Mitochondria produce ATP energy.
6. C. Lysosomes digest foreign substances and worn - out cell parts.
7. F. Cilia are like small oars for movement.
8. B. Flagella act as whipping propellers.
9. B. Active transport requires energy.
10. A. Endocytosis brings something in from outside the cell.
11. D. In a hypotonic solution, water moves into the cell, causing it to lyse/swell.
12. B. The cell would shrivel because ocean salt water is hypertonic.
13. C. In an isotonic solution, solute concentration is equal on both sides of the membrane.

17.
a. Diffusion for transporting O₂ and CO₂.
b. Active transport for transporting glucose.
c. Phagocytosis (a type of endocytosis) when a white blood cell captures bacteria.
d. Osmosis for transporting water.
18.
a. A (Active transport requires energy).
b. P (Diffusion moves particles from high to low concentration).
