Quiz

Question 1

Mitosis

Answer 1

Division of somatic cells
In eukaryotic organisms

Question 2

Mitosis sub-phases

Answer 2

Prophase
Metaphase
Anaphase
Telophase

Followed by cytokinesis

Question 3

Prophase

Answer 3

Chromosome condense
Spindle fibers form
Chromosome are captured by spindle

Question 4

Metaphase

Answer 4

Chromosomes align along equator of the cell

Question 5

Anaphase

Answer 5

-Sister chromatids seperate
Spindle fibers shorten and pull chromatids towards piles

Question 6

Telophase

Answer 6

Spindle fibers disintegrate
Nuclear envelope forms around both groups of chromosomes
Chromosomes revert to extended state
Cytokinesis occurs( enclosing each daughter nucleus into separate cell)

Question 7

Cytokinesis

Answer 7

Is the process after splitting the nuclear chromosomes
The cytoplasm and cell membrane split resulting in 2 daughter cells

Question 8

Plant cells

Answer 8

Undergo cytokinesis by forming a cell plate between the two daughter nuclei

Question 9

Animal cells

Answer 9

Undergo cytokinesis the light the formation of cleavage furrow. A ring of microtubules contract pinching the cell in half

Question 10

Stage of mitosis

Answer 10

Pulled apart to 2

Question 11

Meiosis

Answer 11

A single cell divides into four unique daughter cells.
-a division of the nucleus that reduces chromosome number by half
-combining the genetic info of 1 parent with the other parents to produce a genetically distinct individual

Question 12

Mitosis and meosis similarities

Answer 12

-Both are forms of nuclear division
-Both involve replication
-Both involve disappearance of the nucleus, nucleolus, and nuclear membrane
-Both involve formation of spindle fibers

Question 13

Differences

Answer 13

Meiosis produced daughter cells that have 1/2 the # of chromosomes as the parent, Go from 2n to 1n
-daughter cells produced by meiosis aren’t genetically identical to one another
-in meiosis cell division takes place twice but replications only occurs once.
