Steps of Mitosis
Steps of Meiosis
Mystery Round
100
A pair of chromosomes that contain the same genes in the same loci.
What are homologous chromosomes?
100
REVERSE: What is the difference between mitosis and meiosis?
Mitosis creates two daughter cells - both of which are identical to the parent. Meiosis results in four cells - each containing half the number of chromosomes that the parent cell had. A useful video resource: http://highered.mheducation.com/olcweb/cgi/pluginpop.cgi?it=swf::535::535::/sites/dl/free/0072437316/120074/bio17.swf::Comparison+of+Meiosis+and+Mitosis
100
Step during which each chromosome's sister chromatids move to opposite poles of the cell.
What is Anaphase?
100
This image depicts the number, form, and size of chromosomes found in an organism's cell nuclei.
What is a karyotype.
200
Located near the nucleus, this organelle replicates and then is responsible for developing spindle fibers.
What are centrosomes?
200
Reverse: Does crossing over occur in mitosis? meiosis? both?
Crossing over only occurs in meiosis. Another useful comparison resource: http://www.diffen.com/difference/Meiosis_vs_Mitosis
200
REVERSE: What happens during Metaphase?
Spindle fibers attach at centromeres, chromatids arrange at equator. Flashcards useful link: https://www.studyblue.com/notes/note/n/cell-division-mitosis/deck/1689016

300
Originated during the s-phase of the cell cycle, these consist of two identical halves of a replicated chromosome connected by a centromere. BONUS POINTS: 50pts if you can draw an example on the board.
What are sister chromatids? Link to image answer: http://education-portal.com/academy/lesson/sister-chromatids-definition-lesson-quiz.html#lesson
300
REVERSE: How many steps are in mitosis? meiosis? Bonus: + 5 points for every step you can name
Mitosis = 5 morphologically different phases Meiosis = 8 different phases Note: the number of these phases can change depend on where you make the "cut-off" - some people consider smaller occurences as more steps - however, the phases listed here are the major ones, and the events that occur remain the same.
400
Creates four haploid daughter cells. Bonus: + 25pts if you define haploid and diploid
What is Meiosis?

Challenge: create a chart listing 7 major categories for comparison surrounding mitosis and meiosis, and provide the differences. Bonus: + 50 points for each additional category you can create
Example answer could include categories such as: steps, what organisms it occurs in, products, definition, number of divisions, chromosome numbers, etc. Open to Officiator's judgement
