Mitochondria are found in

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

cellulose

Chromosomes are made from

condensed chromatin

plants cells have plasmodesmata that

connect the cytoplasm of one cell with that of another.

Chloroplasts and mitochondria are similar in that they both

contain DNA

All cells have some characteristics in common; both prokaryotic and eukaryotic cells have

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.
