both plant cells and animal cells
Without gap junctions in certain tissues,
cells would not be able to communicate with each other.
The main structural component of a plant cell wall is

Chromosomes are made from
condensed chromatin
plants cells have plasmodesmata that
connect the cytoplasm of one cell with that of another.

cytoplasm, a plasma membrane, and DNA
Which of the following allows eukaryotic cells and their organelles to move?
cytoskeleton
Surface-to-volume ratio is an important characteristic for cell function; some cells increase their ratio by
developing finger-like projections.
a prokaryotic cell
does not have a membrane bound nucleus
The glycoproteins found in the plasma membrane function in what capacity?
establishing the identity of the cell
The stack of thylakoids labeled "A" in this figure is called
granum
What does the folding of the mitochondrial inner membrane, shown here, provide?
greater surface area for ATP production.
Carrie would like to observe the cilia on the surface of a live paramecium—a single-celled organism. The best device to do this would be a(n)
light microscope
Which of the following is involved in the breakdown of damaged organelles?
lysosome
A tadpole that is undergoing metamorphosis into a frog and no longer requires a tail. Which organelle would help assist in the tail loss?
lysosomes
The cell walls of bacterial cells and plant cells function in
maintaining cell shape
A cell that cannot produce enough energy to function properly most likely has a problem with its
mitochondria
Which of the following organelles would be abundant in a sperm cell that is actively swimming towards an egg cell?
mitochondria
Both plants and animals need mitochondria to
produce ATP
What function does the nucleolus have?
synthesizes ribosomal RNA
In which way are vesicles different from vacuoles?
they are smaller
which of the following is a function of glycoproteins?
to permit cells to recognize one another
Which organelle modifies the contents within vesicles and then repackages them for export?
Golgi apparatus
Cell size is limited because ________ is critical to a cell's function.
surface area to volume ratio
Which of the following human cells would contain cilia?
cell from the trachea (windpipe)
Receptor proteins allow a cell to
bind to signal proteins from other parts of the body.
plant cells have walls but do not have plasma membranes. True or False?
False
Below is a diagram of a bacterium. What part of the bacterial cell does Y represent?
nucleoid
Which of the following structures would NOT be found in a prokaryotic cell?
nucleus
The nucleus has a double membrane that encloses the DNA. Inside the nucleus, the DNA acts as the template to produce mRNA and ribosomes. To exit the nucleus, these molecules must
pass through pores that span both membranes.
Since the plasma membrane blocks the passage of all but a few molecules with specific traits, it is necessary for other molecules to
pass through the membrane via proteins.
What must materials pass through to enter or leave a cell?
plasma membrane
Identify the organelle - function pairing that is mismatched.
plasma membrane - outermost barrier of a plant cell
which feature is found in all cells?
plasma membrane composed of phospholipids
Which structures determine the flexibility of the extracellular matrix?
proteins
Which of the following organelles lacks a membrane?
ribosomes
Which of the following is the correct sequence through the endomembrane system for material that is destined to be secreted from the cell?
rough endoplasmic reticulum - Golgi apparatus - plasma membrane
Which of the following is a type of intracellular protein?
All of the above are types of intracellular proteins.
Which of the following organelles would form a membrane-bound package, also known as a vesicle?
Golgi apparatus
Compared with a eukaryotic cell, a prokaryotic cell
lacks organelles beyond ribosomes.
Which of the following is a correct match?
lysosomes - cellular digestion
plant cells are connected to one another by
plasmodesmata
Eukaryotic cells have DNA enclosed in a double membrane called the nucleus. The nucleus functions to
separate the DNA from other activities that occur in the cytoplasm.
Proteins within the extracellular matrix play a role in communicating between the matrix and the cytoskeleton. true or false?
true
Which of the following is a possible function of the extracellular matrix in animal cells?
All of the answers are possible functions of the extracellular matrix.
Both the nuclear membrane and the plasma membrane are composed of phospholipids. True or False?
True
The hydrophilic parts of the plasma membrane are oriented towards both the outside of the cell and the cytoplasm. True or False?
True
A cell being observed under a microscope has a cell wall, plasma membrane, ribosomes, and chromosomal material that is not found in a nucleus. Based on this information, the cell could be a
bacterial cell
receptor proteins
bind to a signal molecule and bring about a cellular response.
Which of the following is a correct match of a molecule and the location where it is principally used?
mRNA - nucleus and cytoplasm
Which of the following is a correct matching of an organelle and its function?
mitochondrion - cellular respiration
There is an antibiotic called streptomycin that inhibits the function of bacterial ribosomes. Consequently, as the bacterial cells die, the person taking the antibiotics gets better. In other words, the antibiotic destroys bacteria by
not allowing them to produce proteins
