Exam 5: Eukaryotic Cells and Microorganisms

After returning from a trip to Africa,Tom begins to feel very tired and weak.He has severe anemia.A blood smear reveals a protozoan is present in his blood.The health care provider tells Tom he has malaria.Which of the following could be the causative agent of his disease?

The eukaryotic cell organelle that most resembles a bacterial cell is the

You are looking at an organism of some sort under the microscopic lens.It is obviously multicellular,with no cell wall.Your prediction would be that this organism is a:

A/n _____ originates from the Golgi apparatus as one type of vesicle that contains a variety of enzymes for intracellular digestion.

The eukaryotic cell membrane is composed of

Fungi that grow as yeast at one temperature but will grow as mold at another temperature are called

The cell walls of fungi and algae are chemically identical to the prokaryotic cell wall.

An organelle that is a stack of flattened,membranous sacs and functions to receive,modify,and package proteins for cell secretion is the

Plankton are floating communities of helminths.

In the life cycle of the pinworm Enterobius,a common infection in children,the child has the adult worm in the intestine.The adult worm releases eggs,which are then transmitted out of the body via feces.The child will scratch the anal area,picking up the worm eggs and re-inserting them into the mouth.For this helminth life cycle,the human is _____ host.

In humans,helminths generally infect the

When buds remain attached,fungi form a chain of yeast cells called

Fungal asexual spores

Most fungi obtain nutrients from dead plants and animals.These fungi are called

When analyzing a specimen for identification purposes,you detect the presence of large amounts of histone protein.You predict that:

Upon viewing a specimen through microscopic techniques,you realize the cells all contain ribosomes.Based upon this information,you eliminate which of the following from your list of potential microorganisms:

The group of protozoa that are not motile are the

In eukaryotic cells,which of the following contains DNA?

Protists with contractile vacuoles

Larval development of helminths occurs in which host?
