Total questions: 15
Worksheet time: 10mins
Why are buffers important?
They help to build proteins.
They are required for cell division.
They are necessary for cellular growth.
They help to maintain a cell’s homeostasis.
Which would most likely happen if a cell undergoes mitosis, but not cytokinesis?
The cell would have two nuclei.
The cell would not have a nucleus.
The cell would have a small nucleus.
The cell would have one large nucleus.
Which is less likely to be a function of mitosis?
organism growth
body tissue repair
gamete development
asexual reproduction
At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides?
The number of organelles doubles.
Chromosomes must be copied.
Four nuclei must be formed.
The membrane thickens.
Which process produces two somatic cells?
mitosis
meiosis
spermatogenesis
sexual reproduction
When is the distribution of cytoplasm accomplished during mitosis?
anaphase
interphase
cytokinesis
metaphase
Which explains why the nuclear membrane breaks down during mitosis?
So the cytoplasm can be divided.
So the chromosomes can be replicated.
So it makes it easier for the DNA to be mutated.
So the duplicated chromosomes can be separated into new cells.
Which factor BEST explains how many diseases, such as cancer, are formed within the body?
A traumatic injury to the body has occurred.
A disruption in the cell cycle has taken place.
A response by the immune system was triggered by an allergic reaction.
A mutation occurred during the process of crossing over.
During the cell cycle, which process occurs after interphase?
separation of chromosomes into two daughter cells
growth of cell and storage of food and nutrients
synthesis of proteins necessary for cell division
replication and transcription of DNA in the cell
Which describes genetic information prior to the beginning of mitosis?
centrioles
chromatin
centromere
chromosomes
What role does the centromere play in cellular reproduction?
It is the area where microtubules are formed.
It is the area where the nucleus is during cell division.
It is the area of alignment for the chromosomes.
It is the area of attachment for chromatids.
If a daughter cell has 50 chromosomes after mitosis, how many chromosomes were in the parent cell?
25
50
100
150
Which organelle is used to capture and engulf the food into the unicellular organism?
cilium
flagellum
pseudopod
contractile vacuole
If a unicellular organism needs to remove excess water, which structure will most likely carry out this function?
cilia
nucleus
pseudopods
contractile vacuoles
Which example represents chemotaxis?
An amoeba engulfs a food particle.
A paramecium removes excess water.
A paramecium removes excess water.
A bacterium swims towards higher concentrations of glucose.
