Which structure is part of the cell’s skeleton?
a)
Golgi apparatus
b)
microfilaments
c)
plasma membrane
d)
mitochondria
2.
Homeostasis is the process of maintaining a cell’s environment. This includes the regulation of sodium ion (Na+) concentration within the cytoplasm. If too much Na+ is inside a cell, how can the concentration be changed?
a)
More Na+ ions will enter the cell through the plasma membrane.
b)
Excess Na+ ions will leave the cell via osmosis.
c)
Excess Na+ ions will be transported out through membrane protein channels.
d)
More Na+ ions will be transported in through membrane protein channels.
3.
While viewing a slide of rapidly moving sperm cells, a student concludes that these cells require a large amount of energy to maintain their activity. What organelles provide this needed energy?
a)
vacuoles
b)
ribosomes
c)
chloroplasts
d)
mitochondria
4.
On a laboratory exam, a student is asked to determine if the cells under a microscope are plant cells or animal cells. What might the student look for?
a)
chloroplasts and a cell wall
b)
ribosomes and vacuoles
c)
a nucleus and ribosomes
d)
a cell membrane and mitochondria
5.
Which of the following enclose their DNA in a nucleus?
a)
prokaryotes
b)
bacteria
c)
eukaryotes
d)
viruses
6.
Which of the following is a function of the nucleus?

stores DNA

7.
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
a)
water to move into the cell.
b)
water to move out of the cell.
c)
solutes to move into the cell.
d)
solutes to move out of the cell.
8.
A scientist at the polar ice cap was studying an ice sample from hundred of meters below the surface. While examining the ice, the scientist found some cells from many years ago. Using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. What kind of organism did the scientist find?
a)
animal
b)
bacteria
c)
plant
d)
He did not have enough information.
9.
Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes and event that results from mitosis but NOT meiosis?
a)
two stages of cell division
b)
replication of cellular genetic material
c)
daughter cells that are identical to the parent cell
d)
four daughter cells that are produced from each parent cell
10.
How are sexual reproduction and asexual reproduction different from each other?
a)
sexual reproduction requires two parents and asexual reproduction requires only one parent
b)
asexual reproduction requires two parents and sexual reproduction requires only one parent
c)
mutation rates are lower in sexual reproduction than in asexual reproduction
d)
asexual reproduction occurs only in multicellular organisms
11.
Which type of reproduction leads to increased genetic variation on a population?
a)
Parthenogenesis
b)
asexual reproduction
c)
Sexual reproduction
d)
Vegetative reproduction
12.
Which of the following phrases best describes cancer?
a)
absence of cyclins in the DNA
b)
miltiple gene mutations on a chromosome of DNA
c)
uncontrolled cell growth caused by mutations in genes that control the cell cycle
d)
presence of genetic defects caused by hereditary disorders
13.
A scientist wants to change the DNA of a sexually reproducing organism and have the new DNA present in every cell of the organism. In order to do this after fertilization, she would change the DNA in which of the following?
a)
zygote
b)
placenta
c)
testes of the father
d)
ovaries of the mother
14.
Which of the following best describes meiosis?
a)
It is carried out in all tissues that require cell replacement.
b)
It occurs only in cells in the reproductive structures of organisms.
c)
It happens in all tissues except the brain and spinal cord.
d)
It is the first stage of mitosis.
