Unit 7 Test Review Pt1 - 7.2-.5
Standards
HS-LS1-4: Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
2
Interphase - longest phase of cell cycle
G1 - replicate organelles
S - replicate DNA, chromatids form
G2 - prepares to divide
PMAT - Mitotic Phase/Nuclear Division
Cytokinesis
Cell Cycle - Interphase & Mitosis
3
Interphase - longest phase of cell cycle
G1 - replicate organelles
S - replicate DNA, chromatids form
G2 - prepares to divide
PMAT - Mitotic Phase/Nuclear Division
Cytokinesis
Cell Cycle - Interphase & Mitosis
4
Prophase - spindle forms & attaches to chromosomes
Metaphase - spindle lines up chromosomes in middle
Anaphase - sister chromatids separate as microtubules shorten
Telophase - daughter cells form
Cytokinesis - cytoplasm separates
Mitosis - Nuclear Division
5
Multiple Choice
What is the importance of microtubules in cell division?
They provide a pathway for organelles to move into the newly formed cell.
They organize and pull the chromosomes apart.
They start the process of cytokinesis.
They reform the nucleus in the divided cell.
6
Multiple Choice
What is shown in the figure?
The figure shows stem cell differentiation.
The figure shows the steps involved in DNA replication.
The figure shows structures in a cell.
The figure shows where mitosis occurs in the cell cycle.

Mitosis
Body cells replicate DNA
Parent cell is diploid and has 2 sets of chromosomes
(di = two; ploid = chromosome sets)
Two, diploid, genetically identical daughter cells result
10
Multiple Choice
Use the image to answer the question. Which type of cell is shown in the figure?
triploid cell
diploid cell
haploid cell
polyploid cell
11
Multiple Choice
Define mitosis:
takes one cell and replicates it into two genetically unique cells.
takes one cell and replicates it into two genetically identical cells.
takes one cell and replicates it into four cells, each with half of the original cell's genetic information.
takes two cells, one form each parent, and replicates it into four genetically unique cells.
12
Multiple Choice
During mitosis, what happens to the parent cell?
It produces 3 daughter cells.
It produces 2 daughter cells.
It produces 4 daughter cells.
It produces 1 daughter cell.
13
Totipotent cells: 1st type of stem cells that form in the embryo
Pluripotent cells: 2nd type of stem cell to form in the embryo
Multipotent cells: Adult stem cells that can become many different types of specialized cells within a tissue or organ
What is the difference?
14
Multiple Choice
Immediately after an embryo forms, it begins to replicate new cells. What is the most likely type of cells that form during the first few divisions?
totipotent cells
oligopotent cells
multipotent cells
pluripotent cells
