Mitosis and Cytokinesis Part 2

Question 0

List all 6 phases of cell life in the order in which they occur:

Answer 0

Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis

Question 1

How do organisms grow and get bigger?

Answer 1

More cells are produced within an organism which causes it to grow larger over time. Also, as more cells are produced, the cells are also able to grow larger over time.

Question 2

What is the term called that means “colored body.”

Answer 2

Chromosomes

Question 3

What material(s) form across the cell which will serve as transportation routes for the moving chromosomes during cell division?

Answer 3

-Spindle fibers

Question 4

What are the the hereditary units called that have the codes to determine your traits or characteristics?

Answer 4

-DNA

Question 5

What structure holds the two sister chromosomes together during the early phases of cell division?

Answer 5

-Centromeres

Question 6

Do all organisms on Earth have the same number of chromosomes? If not, do all organisms within the same species have the same amount of chromosomes?

Answer 6

-Not every organism has the same number of chromosomes. However, every organism with a specific species will have the same amount of chromosomes. (ex. Humans)

Question 7

What are Centrioles?

Answer 7

Structures that develop in animal cells during prophase, which move towards the ends of the cell and act as anchors for the spindle fibers.

Question 8

___________ is when a nuclear membrane forms around the new set of chromosomes at both ends.

Answer 8

Telophase

Question 9

____________ is when the cytoplasm is squeezed down or pinched into two nearly equal parts.

Answer 9

Cytokinesis

Question 10

____________ is when the chromosomes line up in the center of the cell and attach to the splindle.

Answer 10

Metaphase

Question 11

____________ is when the chromosomes and organelles are duplicated or copied.

Answer 11

Anaphase

Question 12

____________ is when the nuclear membrane breaks down and spindles begin to form.

Answer 12

Prophase

Question 13

____________ is when the sister chromosomes separate from each other and move to opposite ends of the cell.

Answer 13

Interphase

Question 14

Define Mitosis:

Answer 14

The duplication of a nucleus into two nuclei with identical DNA/genetic information.

Question 15

What are the differences between cytokinesis in the plant cells versus animal cells?

Answer 15

-The main difference is that in plant cells, a cell plate forms during cytokinesis whereas in animal cells there is just a furrow (cleavage) that pinches the cell in half. -Instead of a cell plate, animal cells develop a contractile ring. -In animal cells, the spindle degenerates. -In plant cells, the vesicles form a cell plate by fusing together. -Animal cells develop a mid-body.
