Question 1

The study of cell structure and function is called ____.&#10;A) physiology&#10;B) cytology&#10;C) biology&#10;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?&#10;A) the membrane and the cytoplasm&#10;B) the nucleus and the organelles&#10;C) the nucleus and the cytoplasm&#10;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?&#10;A) ribonucleic celluloid&#10;B) red blood cell&#10;C) ribosome blood clot&#10;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?&#10;A) ribosomes&#10;B) endoplasmic reticulum&#10;C) cytoskeleton&#10;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?&#10;A) exocytosis&#10;B) endocytosis&#10;C) osmosis&#10;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?&#10;A) the ability of a solution to affect the volume and pressure inside the cell&#10;B) the pressure outside the cell being affected by other cells within the bloodstream&#10;C) the breakdown of the cellular structure due to enzyme abnormalities&#10;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?&#10;A) Endocytosis is the movement of substances out of the cell; exocytosis is the movement of substances into the cell.&#10;B) Endocytosis requires an ATP to transport substances into the cell; exocytosis does not require an ATP.&#10;C) Endocytosis is a transport mechanism that brings substances into the cells; exocytosis moves substances out of the cells.&#10;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?&#10;A) A cell divides in half.&#10;B) A cell splits into one &#34;mother&#34; cell and two identical &#34;daughter&#34; cells.&#10;C) A cell dies.&#10;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?&#10;A) prophase, metaphase, anaphase, and telophase&#10;B) prophase, G 1 phase, anaphase, S phase&#10;C) metaphase, prophase, telophase, and anaphase&#10;D) G 1 phase, G 2 phase, S phase, and G 0 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?&#10;A) regeneration of the cell&#10;B) cell mutation&#10;C) cell suicide&#10;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.
