Exam 5: Cell Structure

Lysosomes can be called the "garbage disposals" of the cell.

Cytoplasm is another term for cytosol.

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

The cell's internal supporting framework is called the cytoskeleton.

All of the cell extensions-microvilli, cilia, and flagella-have basically the same structure. They only differ in number per cell and length.

Which organelles consist of vesicles that have pinched off from the Golgi apparatus?

The functions of the nucleus are regulated by RNA.

Which of the following is not true about ribosomes?

The largest human cell, measuring about 150 mm, is a:

One function of the microvilli is to increase the surface area of a membrane to provide for more efficient absorption.

Match each cell structure with its corresponding description or function. -One of the largest structures in the cell; contains DNA

An area of cytoplasm that coordinates the building and breaking of microtubules is called:

The main function of the ribosome is to provide energy to the cell.

Each of the following is an example of the plasma membrane function except:

A list of the cell fibers from largest to smallest would read:

Cell connections called desmosomes are like Velcro holding cells together.

The barrier function of the plasma membrane is accomplished by the:

Schleiden and Schwann were the first scientists to see cells.

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

Match each cell structure with its corresponding description or function. -Vesicles that contain catalase that are important in metabolic reactions involving hydrogen peroxide
