Which of the following correctly describes the
function of the cell membrane?
regulate what enters and exits the cell
work with other cells to maintain homeostasis
build proteins and lipids for the cell
provide structure and support for the cell
Which of the following correctly describes cell walls?
Most organisms’ cells have cell walls including
plants, fungi and bacteria
Only plant cells have cell walls
Only animal cells lack cell walls
Animal cells and a few protists are the only cells
that have cell walls
If two cells taken from the same multicellular organism have significant structural differences (shape, organelles, etc.). What can you infer about the two cells?
It doesn’t mean anything – all cells work in exactly the same way if they are from the same organism.
The two cells would perform significantly different functions within the organism.
Even though the cells look different, they would perform similar functions.
One cell is clearly an alien invader and must be neutralized before it wipes out all life on Earth.
What the term for the specialized structures found inside cells?
eukaryotic
nuclei
organelles
prokarytotic
Which two structures are responsible for the fact that plant cells are very rigid compared to animal cells?
chloroplasts and vacuoles
a large vacuole and the cell wall
peroxisomes and cytoplasm
mitochondria and cytoskeleton
Which of the following are key differences between prokaryotic and eukaryotic cells? Circle all that apply.
prokaryotic do not contain DNA; eukaryotic do
eukaryotic contain organelles like mitochondria and
Golgi apparatus; prokaryotic do not
eukaryotic contain a nucleus; prokaryotic do not
prokaryotic only have a cell wall as a covering;
eukaryotic have cell membranes
Which of the following correctly describes the structure of the cell membrane?
a blend of carbohydrates and protein filaments
a solid protein wall
two layers of lipids with nucleic acids between the layers
two layers of lipids with proteins inserted through the layers
Which of the following structures would you expect to find more of in a cell that requires a lot of energy?
mitochondira
cytoskeleton
smooth ER
cell membrane
What material are most cell structures made of?
carbohydrates
membrane material
water
cytoplasm
Which type of organism is made of prokaryotic cells?
plants
bacteria
protists
animals
Which of the following correctly states a reason why scientists believe mitochondria and chloroplasts are descended from free-living bacteria?
They generate energy for cells.
They are sometimes found living on their own.
They make proteins for cells.
They have their own DNA that resembles bacterial DNA
