Question 1

The study of cell structure and function is called ____.
A) physiology
B) cytology
C) biology
D) mitosis

Accepted Answer

The study of cellular structure and function is called cytology.

Question 2

The inside of a cell is made up of two components. What are these two components?
A) the membrane and the cytoplasm
B) the nucleus and the organelles
C) the nucleus and the cytoplasm
D) the nucleus and the mitochondrion

Accepted Answer

The inside of the cell is divided into two compartments: the nucleus and the cytoplasm.

Question 3

What does RBC stand for?
A) ribonucleic celluloid
B) red blood cell
C) ribosome blood clot
D) ribosome blood chromatin

Accepted Answer

A red blood cell (RBC), for example, is tiny, whereas a single nerve cell may measure 4 feet in length.

Question 4

Which of the following is NOT an organelle within they cytoplasm?
A) ribosomes
B) endoplasmic reticulum
C) cytoskeleton
D) cilia

Accepted Answer

The endoplasmic reticulum (ER) is a network of membranes within the cytoplasm; the cytoskeleton helps maintain the shape of the cell and assists the cell in various forms of cellular movement; and ribosomes are cytoplasmic organelles involved with protein synthesis.

Question 5

Which of the following is considered to be a passive transport mechanism?
A) exocytosis
B) endocytosis
C) osmosis
D) equilibrium

Accepted Answer

Osmosis is a special case of diffusion. Osmosis is the diffusion of water through a selectively permeable membrane.

Question 6

Which of the following best describes tonicity?
A) the ability of a solution to affect the volume and pressure inside the cell
B) the pressure outside the cell being affected by other cells within the bloodstream
C) the breakdown of the cellular structure due to enzyme abnormalities
D) the strength of the cell membrane

Accepted Answer

Tonicity is the ability of a solution to affect the volume and pressure within a cell.

Question 7

What is the difference between endocytosis and exocytosis?
A) Endocytosis is the movement of substances out of the cell; exocytosis is the movement of substances into the cell.
B) Endocytosis requires an ATP to transport substances into the cell; exocytosis does not require an ATP.
C) Endocytosis is a transport mechanism that brings substances into the cells; exocytosis moves substances out of the cells.
D) Endocytosis does not require an ATP to transport substances into the cell; exocytosis does require an ATP to move substances out of the cell.

Accepted Answer

Endocytosis is a transport mechanism that involves the intake of food or liquid by the cell membrane. Whereas endocytosis brings substances into the cells, exocytosis moves substances out of the cells

Question 8

What occurs during mitosis?
A) A cell divides in half.
B) A cell splits into one "mother" cell and two identical "daughter" cells.
C) A cell dies.
D) A cell mutates into abnormal cancerous cells.

Accepted Answer

Mitosis, which is involved in bodily growth and repair, is the splitting of one mother cell into two identical "daughter cells."

Question 9

Which of the following best describes the sequence of events in the cell mitotic cycle?
A) prophase, metaphase, anaphase, and telophase
B) prophase, GS1U1B11S1U1B0 phase, anaphase, S phase
C) metaphase, prophase, telophase, and anaphase
D) GS1U1B11S1U1B0 phase, GS1U1B12S1U1B0 phase, S phase, and GS1U1B10S1U1B0 phase

Accepted Answer

Mitosis splits a cell into two genetically identical cells. There are four stages of mitosis: prophase, metaphase, anaphase, and telophase.

Question 10

What is the meaning of apoptosis?
A) regeneration of the cell
B) cell mutation
C) cell suicide
D) cell hibernation

Accepted Answer

There is also a programmed sequence of events that leads to cell death called apoptosis, or cell suicide. Apoptosis helps rid the body of old, unnecessary, and unhealthy cells. Because the body replaces a million cells per second, the elimination of some cells by apoptosis is necessary.
