Exam 5: Cell Structure

Smooth endoplasmic reticulum is the organelle that supplies membrane material for use throughout the cell.

Lysosomes are vesicles that have been pinched off from the smooth endoplasmic reticulum.

Match each term to the phrase that describes it best. -Tiny cylinders that can be found near the boundaries of the centrosomes

The watery fluid in the cell is called cytosol.

Which of the following organelles is considered a nonmembranous organelle?

The protein-processing units of the Golgi apparatus are called cisterna.

Explain the process by which a protein is processed in preparation for being released by the cell, starting at the ribosome and ending at the cell membrane.

How do vesicles move from place to place in an organized way within the cell?

Joanne, a 75-year-old patient, has an active peptic ulcer. Describe the cellular organelles involved in synthesizing digestive enzymes for the stomach.

In the cell membrane, the hydrophilic part of the phospholipid molecule:

Granules or threads within the nucleus are called:

The plasma membrane can be described as a double layer of phospholipid molecules.

The nucleus is the only structure in the cell that contains DNA.

The membranous structure containing substances that protect the cell from harm are:

Match each cell structure with its corresponding description or function. -Tubular network in the cell with no ribosomes that synthesize lipids and carbohydrates

DNA is a major constituent of which cell organelle?

The structure in cells that is associated with the enzymatic breakdown (digestion) of foreign material is the:

The name nucleus comes from the Greek word for color.

The identification function of the cell membrane is carried out by the:

The enzyme catalase is an important chemical in the functioning of the:
