The photo of the Proteus cell is probably a swarmer cell. How would you know?

How is the cell cycle controlled? Why is it important to regulate progression through the cell cycle?

An electrochemical cell that produces a current from an oxidation-reduction reaction is often called a(n)___ cell.

A solution surrounding a cell is hypertonic if:
a. it contains fewer nonpenetrating solute particles than the interior of the cell
b. it contains more nonpenetrating solute particles than the interior of the cell
c. it contains the same amount of nonpenetrating solute particles as the interior of the cell

Choose the word or phrase that best answers the question. Which can be observed only in a plant cell? A. cell membrane, B. cell wall, C. nucleus, D. ribosome.

Discuss the consequences of too little cell division and too much cell division.

Endosymbiosis involves one cell invading and living inside another cell. (T/F)

What evolutionary advantages does a eukaryotic cell have compared with a prokaryotic cell?

In what way does a B cell that encounters an antigen function as an antigen-presenting cell?

Cell walls. Although these quantities vary from one type of Blo cell to another, a cell can be $2.0 \mu \mathrm{m}$ in diameter with a cell wall $50.0 \mathrm{~nm}$ thick. If the density (mass divided by volume) of the wall material is the same as that of pure water, what is the mass (in $\mathrm{mg}$ ) of the cell wall, assuming the cell to be spherical and the wall to be a very thin spherical shell?

Could a bacterial cell dispense with a cell wall if it had a capsule? Why or why not?

Identify contributions to the cell potential when a current is being drawn from the cell.

A voltaic cell in which the electrolyte is a paste is called a $\underline{\text{wet cell}}$

There is a built-in function function called cellfun that evaluates a function for every element of a cell array. Create a cell array, then call the cellfun function, passing the handle of the length function and the cell array to determine the length of every element in the cell array.
