Question

4. Complete the following table. Mitosis Meiosis MitosisMeiosis Synapsis (Yes or no Crossing over (When) Anaphase I results When do centromeres divide No. of divisions No. of cells resulting Anaphase II results No. of chromosomes in daughter cells Assume cell divisions are occurring on the arrows in this gen- eralized plant life cycle. Show where mitosis and meiosis occur. 5. Multicellular diploid plant Spore Multicellular haploid plant Starting with a diploid cell (A) that has 2 homologous chromo- somes (2N-2), which diagram below shows how the chromo- somes would be arranged at each of the following times: During metaphase of mitosis? During metaphase I of meiosis? During metaphase II of meiosis? 6. Zygote Sta

Answer 1

4. Complete the following table

Answer:

STAGES	MITOSIS	MEIOSIS
Synapsis	No	Yes
Crossing over (when)	No	Synapsis
Anaphase I results	sister chromatids breaks and move towards oppsite poles	sister chromatids remain attached at their centromeres and move together toward the poles
When do centromeres divide	Anaphase	Anaphase II
No. of divisions	1	2
No. of cells resulting	Two diploid cells	Four haploid cells
Anaphase II results	Single phase only resulting in separate sister chromatids, move towards poles	Two separate chromatids are formed
No. of chromosomes in daughter cells	remains the same as of parent	Reduced to half the number
