Are the cells depicted plant or animal cells? animal a. Explain your answer. Cells are round, no cell plate, pinching b. If it were the other type of cell what would be different in the diagrams? Square, cell plate ____________________14. 13. What is the longest phase of the cell cycle? interphase Why is mitosis important? Duplicate nuclear material for 2 daughter cells 14. Predict what would happen if an individual had faulty spindle fibers. Daughter cells would end up with the wrong number of chromosomes 15. Predict what would happen if cytokinesis was skipped. Cells would have too many chromosomes; cells wouldn’t function properly because they would be too big. 16. What is the difference between cell plate and cleavage furrow? below 17.
