let's imagine a diploid plant cell.

a) draw the five stages of mitosis and meiosis assuming N=3

b) briefly explain each step of mitosis and meiosis.

Expert Solution

Mitosis is 4 substages; prophase, metaphase, anaphase, and telophase

In prophase, chromatin network coil and seen as distinct long thread like structures and nuclear membrane gradually disappears.

In Metaphase, chromosomes align at metaphase plate facing opposite poles. Spindle fibres from opposite poles attach to centromeres. In late metaphase, centromere divides and stat separating.

Anaphase is marked by separation of chromosomes to the opposite poles.

In telophase, they uncoil and elongate to form thin chromosomes.

1- Write a comparison of the stages of meiosis to the stages of mitosis. Which stages are unique to meiosis and which stages have the same events in both meiosis and mitosis? 2-On a piece of paper construct a Venn diagram to describe the similarities and differences between the cytokinesis mechanisms found in animal cells versus those in plant cells. 3- Nondisjunction is when chromosomes fail to separate properly during meiosis. Describe what would happen to the gamete chromosome number...

A. Starting with a diploid cell that has 8 chromosomes, draw out/compare and contrast mitosis with meiosis. Label and describe what happens during each stage as well as the maternal and paternal chromosomes. Also label the reductional and equational division for both processes when appropriate. B. Using 2 of the chromosomes you created above (one maternal one paternal), discuss how sexual reproduction creates genetic variation for evolution act upon during meiosis. How does this compare to asexual reproduction for eukaryotes...

What is the chromosome number of a cell (diploid or haploid) at the beginning of Mitosis? Are the chromosomes duplicated or unduplicated at the beginning of Mitosis? What is the chromosome number of a cell at the end of Mitosis? Are duplicated chromosomes present at the end of Mitosis or unduplicated chromosomes?
