Question

for questions 14 - 17 choose \a\ for prokaryotic and \b\ for eukaryotic. bacteria and archaea would be an example of this type of cell. fungi and other complex organisms would have this type of cell. 16. i am a unicellular organism with ribosomes, but no nucleus for my circular chromosome. 17. i am a complex unicellular organism with membrane - bound organelles, like mitochondria. 18. what is the name of the organelle that only animal cells have? a. cell wall b. chloroplasts c. cytoskeleton d. centrosome 19. for question 19 select/bubble all that apply. what organelles are in a plant cell that are not in an animal cell. (1.5pt) a. chloroplasts b. many small vacuoles c. one central vacuole d. cell wall e. centrosome 20. in the picture, which cell belongs to a plant? a. cell 1 b. cell 2 c. both d. neither 21. which organelles are used to help with movement? a. mitochondria, nucleus, and cytoplasm b. ribosome, endoplasmic reticulum and golgi apparatus c. cell membrane, lysosome, and nucleolus d. vesicle, flagella, and cilia 22. what organelle is hard to see because it acts like bones by providing structure for the cell? a. cell wall b. cytoplasm c. cytoskeleton d. cellulose

Explanation:

1. Bacteria and Archaea are prokaryotes, so the answer for the statement about them is A. Prokaryotic cells lack a true nucleus and membrane - bound organelles.
2. Fungi and complex organisms have eukaryotic cells which have a nucleus and membrane - bound organelles, so the answer is B.
3. A unicellular organism with ribosomes but no nucleus for its circular chromosome is a prokaryote, so the answer is A.
4. A complex unicellular organism with membrane - bound organelles like mitochondria is a eukaryote, so the answer is B.
5. Centrosomes are organelles that are only in animal cells. Cell walls are in plant and prokaryotic cells, chloroplasts are in plant cells, and cytoskeletons are in both plant and animal cells. So the answer is d.
6. Chloroplasts, one central vacuole, and cell walls are in plant cells but not in animal cells. Many small vacuoles are more common in animal cells and centrosomes are in animal cells. So the answers are a, c, d.
7. Plant cells have a cell wall and a large central vacuole. Cell 2 appears to have these features, so the answer is b.
8. Vesicles, flagella, and cilia are involved in cell movement. Mitochondria are for energy production, ribosomes for protein synthesis, etc. So the answer is d.
9. The cytoskeleton provides structural support like bones in a cell and can be hard to see. The cell wall is more rigid and obvious in plant cells, cytoplasm is the jelly - like substance, and cellulose is a component of the cell wall. So the answer is c.

Answer:

1. A. Prokaryotic
2. B. Eukaryotic
3. A. Prokaryotic
4. B. Eukaryotic
5. d. Centrosome
6. a. Chloroplasts, c. One central vacuole, d. Cell wall
7. b. Cell 2
8. d. Vesicle, flagella, and cilia
9. c. Cytoskeleton
