Question 1

Which statement best describes the principle of 'structure and function are complementary' in cell theory?

Accepted Answer

The biochemical functions of cells are dictated by the shape of the cell and specific subcellular structures.

Question 2

According to cell theory, which of the following is NOT true?

Accepted Answer

Cells can arise spontaneously from non-living matter.

Question 3

A nerve cell is specialized for gathering information and controlling body functions. Which structural feature is most likely to support this function?

Accepted Answer

Long, branching extensions to transmit electrical signals.

Question 4

Which of the following best explains why there are over 200 different types of human cells?

Accepted Answer

Each cell type has a unique combination of size, shape, and subcellular components that determine its function.

Question 5

Which of the following is NOT one of the three basic parts of a human cell?

Accepted Answer

Cell wall

Question 6

A patient is given a hypertonic intravenous solution. What is the expected effect on their red blood cells?

Accepted Answer

Cells will shrink as water leaves the cell.

Question 7

Which equation correctly represents the relationship between solute concentration and water concentration in osmosis?

Accepted Answer

$$C_{water} \propto \frac{1}{C_{solute}}$$

Question 8

Which cell type is most likely to have abundant rough endoplasmic reticulum and Golgi apparatus?

Accepted Answer

Epithelial cell that secretes mucus

Question 9

If a cell is placed in a hypotonic solution, what process occurs and what is the result?

Accepted Answer

Osmosis; water enters the cell, causing it to swell and possibly lyse.

Question 10

Which of the following best describes the function of fibroblasts?

Accepted Answer

Cells that connect body parts, form linings, or transport gases.

Question 11

Which of the following is a direct consequence of the cell theory for multicellular organisms?

Accepted Answer

The health of the organism depends on the health and function of its individual cells.

Question 12

Which cell type is specialized for movement of organs and body parts?

Accepted Answer

Skeletal muscle cell

Question 13

Which of the following is a function of the plasma membrane?

Accepted Answer

It is a flexible boundary that controls what enters and leaves the cell.

Question 14

Which of the following best explains why muscle cells differ in structure from nerve cells?

Accepted Answer

Their size, shape, and subcellular components are specialized for their unique functions.

Question 15

Which of the following is a correct statement about the continuity of life?

Accepted Answer

Cells can arise only from other preexisting cells.
