Mitosis Unit Test 2021
Q1: Based on your observations, how many cells are in anaphase?
19
Q2: Place the phases of a stem cell into the correct order.
mitosis, gene expression, differentiation
Q3; What general type of cell do fibroblasts make?
tissue
Q4; During mitosis, what happens to the parent cell?
It produces 2 daughter cells
Q5; In which phase of mitosis do the chromosomes line up along the center of the cell?
metaphase
Q6; 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
Q7; Why is mitosis a longer and more complicated process of cell division than binary fission?
Mitosis has check points that must be met to continue the cycle
Q8; Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
skin cells
Q9; When scientists and doctors are looking to heal wounds and cure diseases, stem cells are a great option because they can repair damage and grow new specialized cells. From the list, which type of stem cell would be the best option for healing the widest variety of diseases?
embryonic stem cells
Q10; What is the importance of microtubules in cell division?
They organize and pull the chromosomes apart.
Q11; How is cell differentiation different than mitosis?
Cell differentiation produces cells with different gene expressions.
Q12; "Use the image to answer the question." Which type of cell is shown in the figure?
diploid cell
Q13; "Use the image to answer the question." What is a strength in the figure?
The figure shows where mitosis occurs in the cell cycle.
Q14-17 are your own paragraphs :)
A. Mitosis, Gene expression, differentiation
bingus is 100% right
Mitosis: (1 point)
takes one cell and replicates it into two
genetically identical cells.
takes one cell and replicates it into two
genetically unique cells.
takes two cells, one from each parent, and
replicates it into four genetically unique
cells.
takes one cell and replicates it into four
cells, each with half of the original cell's
genetic information.
thx! but I had some extra questions lol.
extra question on the test-
What is a strength in the figure?
Answer: The figure shows mitosis occurs in the cell cycle
