Questions: Cell Division Figures
Directions: Obtain a copy of the diagrams of mitosis and meiosis. Then answer the following questions.
Mitosis Figures: Obtain a copy of the diagrams of mitosis and then answer the following questions:
|Stage||Name of Stage||Describe briefly what is occurring during this stage|
- metaphase plate
- cleavage furrow
Meiosis Figures: Obtain a copy of the diagrams of meiosis. Then answer the following questions.
1. Assume that diagram "A" represents a sex cell in interphase before meiosis. Further assume that the diploid number of this cell is 8 (2n = 8). For each figure, indicate whether it is: (a) is haploid (n) or diploid (2n); (b) the number of chromosomes in the cell; (c) the name of the stage; (d) whether the diagram depicts meiosis I or II; and (e) a brief description of what is occuring.
|Stage||Ploidy (2n or n?)||Chromosome #||Name of Stage||Meiosis I or II?||Describe briefly what is occurring during this stage|
2. Define or describe the following terms/concepts:
Is this a plant or animal cell? Explain.
List the stages in order. The first one is done
How can you tell which chromosomes come from which parent?
