Exam 5: Eukaryotic Cell Structure

Which of the following is a function of the mitochondrion?

A (n)__________ is a special type of lysosome used by a cell to selectively digest and recycle cytoplasmic contents,such as mitochondria.

Which of the following organelles is involved in the modification,packaging,and secretion of materials?

Cilia beat with two distinctive phases.With the __________ stroke,they stroke like an oar,thereby propelling the organism through the water.With the __________ stroke,cilia bend along their length while they are pulled forward. ASM

Flimmer filaments

The nucleolar organizer is a part of a specific chromosome that directs the synthesis of

Long filaments containing microtubules and used for cellular locomotion are called __________ whereas short fibers containing microtubules and used for cellular locomotion are called __________.

Membrane delimited intracellular structures that perform specific functions in cells are called

The Golgi apparatus is comprised of flattened,saclike structures called __________,which may be clustered in one region or scattered throughout the cell.

The membrane bound structure that contains the chromosomes of eukaryotes is called the nucleus.

The __________ is a complex structure or set of structures lying beneath the plasma membrane of many protozoa and some algae,which serves as a supportive mechanism for these cells. ASM

Although similar in function,the eukaryotic ribosome is generally smaller and more complex than the prokaryotic ribosome.

The organelle responsible for harvesting light as an energy source for photosynthesis is the

The major site of cell membrane synthesis is the

The formation of carbohydrate (CO₂ fixation)in the dark reaction of photosynthesis,takes place in the

Chloroplasts are the site for both the light and dark reactions of photosynthesis.

The nucleolus is a highly active region of the nucleus that is required for synthesis of ribosomes.

Like prokaryotic cells,most eukaryotic cells have an external cell wall.

The Golgi apparatus is responsible for the

The majority of mitochondrial proteins are manufactured under the direction of the nuclear DNA by cytoplasmic ribosomes.
