Cell Division The fraction of cells in a population that are undergoing mitosis (the mitotic index) is a convenient way to estimate the length of the cell cycle. You have decided to measure the cell cycle in the kidney of the adult badger by measuring mitotic index. Accordingly, you have prepared kidney sections obtained from unfortunately road-killed badgers collected from Wisconsin. You stained the cells in the sections to make cells in mitosis easy to see. After 3 days of...
In your readings, you learned about cellular division in both plant and animal cells. While they are similar in many ways, some key differences occur late in the mitotic division. Describe the similarities and differences between the cytokinesis mechanisms found in animal cells versus those in plant cells.
Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...
The Cell 69 Experiment 2: Investigating Animal Cells In this exercise, you will visualize human cheek cells from images at www.thebiologyprimer.com/cell. 13. Sketch a single cheek cell. Label the nucleus, nucleolus, cytoplasm, and cell membrane. Were you able to identify any other organelles? If so, what organelles do you think you saw? 14. How is the shape of the cheek cells different from onion cells? Why is the shape of cheek cells different from onion cells? 15. Do you see...
4. (15) You designed a polymer based hydrogel scaffold which can direct neural stem cells (NSCs) to differentiate into neurons in a linear grid. To check whether the cells differentiated, you used immunofluorescence to stain the cells for neural markers MAP-2 and DCX and NSC marker Sox2. a) What data do you expect to see from your immunofluorescence experiment if the NSCs had differentiated? b) Is this experiment sufficient? What other experiments should we do to confirm? (No need to...
11. Eukaryotic cells are most likely to have originated when a. climate changes disturbed natural processes b. a supernatural force intervened c. a comet seeded the earth with the new cells d. one (or more) prokaryotic cell(s) took up residence in another 12. Evidence in support of the endosymbiont hypothesis is a. the remarkable similarity between some organelles and modern prokaryotic cells (size, shape, behavior, reproduction, ribosomes, DNA) b. we see this happening occasionally today c. prokaryotic cells were first...
Do you think that fungal cells have turgor pressure? Design an experiment to test your hypothesis.
72. Looking into your microscope, vou spot an unusual coll Instead of the typical rounded cell shape, the cen dcell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number or to this cell is two buiging ends. It sort of looks like the number 81 You realize that A) undergoing cytokinesis. C) in the G1 phase of interphase. B) in the S phase of interphase. D) about to undergo mitosis....
1. Choose all of the organelles below that you would find in a plant cell, but not in an animal cell. Group of answer choices cytoplasm centrioles large central vacuole choloroplasts cell wall ribosomes 2. Prokaryotic cells: Group of answer choices have membrane bound organelles have a nucleus are much larger than eukaryotic cells can make single-celled or multicellular organisms can only make single-celled organisms 3. Eukaryotic cells: (Choose all that apply) Group of answer choices have a nucleus are...
1. You need to design a drug that kills bacteria without harming human cells. Name 2 cell structures (Cell composition/ parts) that you would consider a potential "targets" for your drug. Briefly explain why you chose each structure. 2. based on your knowledge of certain type(s) organic molecules, why do you think cells have to be maintained at a constant temperature and pH. 3. Give two different examples of using cell wall structure to tell different organism apart.
