Virchow is credited with several key discoveries. Which of the following discoveries was related to cell theory?

The definition of the cell as the basic unit of a plant’s structure

All living cells can only arise by cell division from pre-existing cells

All diseases involving changes in normal cells

None of the answers is correct.

Which of the following conditions is most likely to damage a cell membrane and increase its permeability?

Low temperatures (4– 1 0 ∘ C )

Organic solvents

Hypertonic solutions

Polar solvents

How do ions and relatively large polar molecules pass through cell membranes?

They pass through the hydrophobic tails found in the cell membranes.

They pass through the fatty acids found in the cell membranes.

They pass through proteins found in the cell membranes.

They pass through the hydrophilic heads found in the cell membranes.

The inner membrane of a mitochondrion is highly folded, as shown in the figure. How does this feature help the mitochondrion perform its function?

It decreases the permeability of the membrane so the reactants of respiration stay inside.

It reduces the size of the organelle so it fits in the cytoplasm.

It increases the surface area for the reactions of photosynthesis.

It increases the surface area for the reactions of respiration.
